Robots in food systems: a review and assessment of potential uses.

Management personnel in foodservice, food processing, and robot industries were surveyed to evaluate potential job functions for robots in the food industry. The survey instrument listed 64 different food-related job functions that participants were asked to assess as appropriate or not appropriate for robotic implementation. Demographic data were collected from each participant to determine any positive or negative influence on job function responses. The survey responses were statistically evaluated using frequencies and the chi-square test of significance. Sixteen of the 64 job functions were identified as appropriate for robot implementation in food industries by both robot manufacturing and food managers. The study indicated, first, that food managers lack knowledge about robots and robot manufacturing managers lack knowledge about food industries. Second, robots are not currently being used to any extent in the food industry. Third, analysis of the demographic data in relation to the 16 identified job functions showed no significant differences in responses.

Robotic surgery for gastric gastrointestinal stromal tumors: a systematic review.

Robotic surgery is used for selected gastric gastrointestinal stromal tumours (GISTs), particularly when location makes conventional wedge resection difficult. We synthesised technical, perioperative, pathological, functional and oncological outcomes. PubMed/MEDLINE, Scopus and the Cochrane Library were searched from inception to 14 August 2026. Primary reports with at least three eligible robotic gastric-GIST patients were included. Two reviewers independently selected studies, extracted data and completed design-specific JBI appraisal. Because outcome definitions, denominators and reporting were heterogeneous, findings were synthesised narratively in accordance with SWiM guidance rather than pooled. Twenty-three studies, including six comparative cohorts, were included. Institutional robotic cohorts contained 3-45 eligible patients; one national registry included 1,567 robotic cases. Tumour size ranged from 2.68 ± 1.55 to 7.9 ± 1.8 cm among studies reporting means. Most institutional reports described R0 resection in all eligible patients; exceptions were 23/24 and 24/25, while the registry reported 1,425/1,567 R0 resections. Grade III morbidity occurred in 2/25 patients in one function-preserving series. Registry 30- and 90-day mortality after robotic resection were 0.5% and 0.8%, respectively. Comparative studies did not demonstrate superior postoperative or oncological outcomes with robotic surgery. Robotic gastric-GIST resection appears feasible in selected patients and may facilitate organ-preserving surgery at anatomically challenging sites. Current observational evidence does not establish comparative functional, oncological or economic superiority.

Artificial intelligence enabled social robotic interventions (PARO) in Australian dementia care: A systematic review and meta-analysis.

BACKGROUND: Although there is a growing body of research indicating that Personal Robot/Social Robot could be used in various aspects of care for individuals with dementia, little is known about how well these types of interventions work in an actual hospital setting in Australia. AIMS & OBJECTIVES: The objective of the present systematic review and meta-analysis is to assess the effectiveness of PARO-based socially assistive robotic intervention in terms of its effectiveness outcomes towards the reduction of dementia-related behavioural and psychological symptoms in Australian based healthcare settings. METHODS: A systematic search was conducted across five electronic databases, including MEDLINE (PubMed), EMBASE, CINAHL, PsycINFO, and the Cochrane Library, to identify randomised controlled trials (RCTs) investigating PARO-based socially assistive robotic interventions for dementia in Australian healthcare settings. This review was registered with PROSPERO (CRD420251251916) and followed the PRISMA 2020 guidelines. In addition, the Cochrane Risk of Bias tool (RoB 2) was used to evaluate the risk of bias across all studies. Pooled standardised mean differences (SMD) with 95 % confidence intervals (CI) were calculated for agitation, anxiety, and depression. Heterogeneity across studies was evaluated using the I2 statistic. RESULTS: Six RCTs involving 1444 participants were identified for inclusion in this review. AI-enabled socially assistive robotic interventions, specifically the PARO therapeutic robot, significantly reduced agitation and anxiety when compared to standard treatment or control conditions. The pooled analysis showed that agitation [SMD = -0.44 (95 % CI: -0.70, -0.18) p = 0.0008] and anxiety [SMD = -0.59 (95 % CI: -0.91, -0.27) p = 0.0003] were reduced significantly, while the decrease in depression [SMD = -0.44 (95 % CI: -0.95, -0.07) p = 0.09] scores was non-significant among dementia patients receiving PARO-based socially assistive robotic interventions as compared to the control. The overall risk of bias across all six studies was considered low to moderate. CONCLUSION: PARO-based socially assistive robotic interventions may provide preliminary evidence of effectiveness in reducing agitation and anxiety in individuals with dementia in Australian healthcare, but the evidence regarding the reduction of depression remains unclear. Therefore, additional high-quality trials with consistent methodology and extended follow-up will be necessary to determine both the short-term and long-term clinical efficacy and practicality of implementing these interventions into practice.

Major digestive surgery using a remote-controlled robot: the next revolution.

HYPOTHESIS: A remote-controlled robot can be used to perform computer-enhanced major digestive laparoscopic surgery. DESIGN: Cases series for assessment of the feasibility and safety of this technology in major digestive surgery. SETTING: Tertiary care referral center. PATIENTS: Between September 5, 2001, and December 20, 2001, 5 patients (4 men and 1 woman; mean +/- SD age, 66 +/- 5 years) underwent laparoscopic sigmoidectomy, proctectomy, restoration of continuity after Hartmann operation, Whipple procedure, and right liver lobectomy. In each of the procedures, a remote-controlled robot was used to perform some stages of the surgery. During these stages, the surgeon was seated at a distance from the operating table and performed the surgery using the robot, which offers enhanced intracorporeal tool manipulation and spatial vision. RESULTS: Sigmoidectomy was the only procedure that was completely performed with the robot. For the other procedures, the mean +/- SD duration of robot use was 25% +/- 10% of the operative time. Stages of colorectal surgery, retroportal dissection, 2 anastomoses during a Whipple procedure, hepatic pedicle dissection, and initial hepatotomy were performed using the robot. This technology facilitates laparoscopic anastomoses. The principal drawbacks were the time required for robot mobilization, absence of grip strength feedback, limited availability of adapted surgical tools, and the cost of the system. There was no mortality. Two of the 5 patients experienced complications, a postoperative ileus and unexplained sepsis after the Whipple procedure, both of which were treated medically. CONCLUSIONS: For these procedures, laparoscopic computer-enhanced surgery seems safe and feasible. This introduction of computing to major digestive surgery opens the door to enhanced-reality surgery and new types of surgical education.

Feasibility of robotic laparoscopic surgery: 146 cases.

Theoretically, in laparoscopic surgery, a computer interface in command of a mechanical system (robot) allows the surgeon: (1) to recover a number a number of lost degrees of freedom, thanks to intraabdominal articulations; (2) to obtain better visual control of instrument manipulation, thanks to three-dimensional vision; (3) to modulate the amplitude of surgical motions by downscaling and stabilization; (4) to work at a distance from the patient. These advances improve the quality of surgical tasks in a perfect ergonomic position. The purpose of this paper is to evaluate the feasibility of utilizing a robot in laparoscopic surgery. The first robot-assisted procedure in humans was performed in March 1997 by our team. One hundred forty-six patients underwent robot-assisted laparoscopic surgery. Between March 1997 and February 2001 a nonconsecutive series was performed of 39 antireflux procedures, 48 cholecystectomies, 28 tubal reanastomoses, 10 gastroplasties for obesity, 3 inguinal hernias, 3 intrarectal procedures, 2 hysterectomies, 2 cardiac procedures, 2 prostactectomies, 2 arteriovenous fistulas, 1 lumbar sympathectomy, 1 appendectomy, 1 laryngeal exploration, 1 varicocele ligation, 1 endometriosis cure, 1 neosalpingostomy, 1 deferent canal. The robot (Da Vinci system, Intuitive Surgical, Mountain View, CA), consists of a console and a cart with three articulated robot arms. The surgeon sits in front of the console, manipulating joysticklike handles while observing the operative field through binoculars that provide a three-dimensional picture. This computer is capable of modulating these data by eliminating physiologic tremor and by downscaling the amplitude of motions by a factor 5 or 3 to one. This study has demonstrated the feasibility of several laparoscopic robotic procedures. There is no morbidity related to the system. Operating time and the hospital stay were within acceptable limits. The system seems most beneficial in intra-abdominal microsurgery or for manipulations in a very small space. Optimized ergonomics and increased mobility of the instrument tips are beneficial in many steps of abdominal surgical procedures.

Robotic surgery, telerobotic surgery, telepresence, and telementoring. Review of early clinical results.

Although laparoscopic cholecystectomy rapidly became the standard of care for the surgical treatment of cholelithiasis, very few other abdominal or cardiac operations are currently performed using minimally invasive surgical techniques. The inherent limitations of traditional laparoscopic surgery make it difficult to perform these operations. We, and others, have attempted to use robotic technology to (a) provide a stable camera platform, (b) replace two-dimensional with three-dimensional (3-D) imaging, (c) simulate the fluid motions of a surgeon's wrist to overcome the motion limitations of straight laparoscopic instruments, and (d) offer the surgeon a comfortable, ergonomically optimal operating position. In this article, we review the early published clinical experience with surgical robotic and telerobotic systems and assess their current limitations. The voice-controlled AESOP robot replaces the cameraperson and facilitates the performance of solo-surgeon laparoscopic operations. AESOP provides a stable camera platform and avoids motion sickness in the operative team. The telerobotic Zeus and da Vinci surgical systems permit solo surgery by a surgeon from a remote sight. These telerobots hold the camera, replace the surgeon's two hands with robotic instruments, and serve in a master-slave relationship for the surgeon. Their robotic instruments simulate the motions of the surgeon's wrist, facilitating dissection. Both telerobots use 3-D imaging to immerse the surgeon in a three-dimensional video operating field. These robots also provide operating positions for the surgeon console that are ergonomically superior to those required by traditional laparoscopy. The technological advances of these telerobots now permit telepresence surgery from remote locations, even locations thousands of miles away. In addition, telepresence permits the telementoring of novice surgeons who are performing new procedures by expert surgeons in remote locations. The studies reviewed here indicate that robotics and telerobotics offer potential solutions to the inherent problems of traditional laparoscopic surgery, as well as new possibilities for telesurgery and telementoring. Nonetheless, these technologies are still in an early stage of development, and each device entails its own set of challenges and limitations for actual use in clinical settings.

Efficiency of manual versus robotical (Zeus) assisted laparoscopic surgery in the performance of standardized tasks.

BACKGROUND: The objective of this study was to compare the efficiency of manual and robotically assisted laparoscopic surgery. METHODS: To evaluate the surgical efficiency in a set of basic endoscopic movements, 20 medical students without any surgical experience were selected to perform at random a set of laparoscopic tasks either manually or robotic assisted (Zeus). This task consisted of dropping beads into receptacles, running a 25-cm rope, capping a hypodermic needle, suturing, and performing a laparoscopic cholecystectomy on a cadaver liver of a pig. A quantitative time-action analysis was performed to evaluate the efficacy and skill performance in terms of time and the number of actions. RESULTS: The dropping beads exercise and the laparoscopic cholecystectomy required more time when performed with robotic assistance, as compared with manual performance (respectively, median, 78.5 s; range, 63 - 122 s vs median, 144.5 s; range, 100 - 169 s; p <0.01 and median, 34.0 min; range 11-44 min vs median, 46.5 s; range, 21 - 79 min; p = 0.05). A tendency toward fewer total actions in all the robotically assisted exercises was observed. However, significance was shown only in the rope-passing task (median, 71; range, 59 - 87 vs median, 62; range, 57-80; p = 0.05). Grasping the beads, the rope, and either the needle or the cap were tasks that required fewer actions to complete when performed with robotically assistance (respectively, median, 11; range, 10 - 14 vs median, 12.5; range, 11 - 15; p <0.01; median, 56; range, 55 - 60 vs median, 60.5 min; range, 55 - 65; p = 0.03, and median, 6; range, 4 - 21 vs median, 10.5; range, 6 - 38; p = 0.02). As compared with the robotically assisted rope-passing exercise, more failures were made in the manually performed procedure (p = 0.03), mainly caused by unintentional dropping of the rope (p = 0.02). CONCLUSIONS: Robotically assisted laparoscopic surgery by participants without any surgical experience might require more time, but actions can be performed equally or more precisely as compared with manual laparoscopic surgery.

Comparison of laparoscopic skills performance between standard instruments and two surgical robotic systems.

BACKGROUND: Our objective was to compare the performance of laparoscopic tasks by surgeons using standard laparoscopic instruments and two surgical robotic systems. METHODS: Eighteen surgeons performed tasks in a training box using three different instrument systems: standard laparoscopic instruments, the Zeus Robotic Surgical System, and the da Vinci Surgical System. Basic tasks included running a 100-cm rope, placing beads onto pins, and dropping cotton peanuts into cylinders; fine tasks included intracorporeal knot tying and running stitches with 4-0, 6-0, and 7-0 sutures. Time (in seconds) required and precision (number of errors) in performing each task were recorded. Analysis of variance with pair-wise comparisons using the Bonferroni method and Friedman's nonparametric test were used for statistical analysis. RESULTS: Standard instruments performed significantly faster than either robotic system on the rope and bead tasks (p <0.05), whereas da Vinci performed significantly faster than Zeus in all three basic tasks (p <0.05). No significant difference in precision was found between standard instruments and the robotic systems on any of the basic tasks. Knot-tying and running-suture time were similar between standard instruments and da Vinci, which were significantly faster than Zeus (p <0.05) for all suture sizes. The robotic systems were similar in precision for fine suturing tasks and were significantly more precise in knot tying (Zeus and da Vinci) and running sutures (da Vinci) than standard instruments (p <0.05). CONCLUSIONS: Basic laparoscopic task performance is generally faster and as precise using standard instruments compared to either robotic system. In performing fine tasks, neither robotic system is faster than standard instruments, although they may offer some advantage in precision.

Robotic surgery: identifying the learning curve through objective measurement of skill.

BACKGROUND: The incorporation of new devices into surgical practice often requires that surgeons acquire and master new skills. We studied the learning curve for intracorporeal knot tying in robotic surgery. METHODS: We developed an objective scoring system to evaluate knot tying and tested eight attending surgeons during 3 weeks of training on a surgical robot. Each performed intracorporeal knot tying tasks both before and after robotic skills training. These performances were compared to their laparoscopic knots and analyzed to determine and define skill improvement. RESULTS: Baseline laparoscopic knot completion took 140 sec (range, 47-432), with a mean composite score of 77 (100 possible), whereas robotic knot tying took 390 sec, with a mean composite score of 40. After initial robotic training, times decreased by 65% to 139 sec and scores increased to 71. With more training, completion times and composite scores were improved and errors were reduced. CONCLUSION: Like any new technology, surgical robotics requires dedicated training to achieve mastery. Initially, even experienced laparoscopists may register an inferior performance. However, after adequate training, surgeons can exceed their laparoscopic performance, completing intracorporeal knots better and faster using robotics.

Fruit harvesting robots in Japan.

We have developed harvesting robots for tomato, petty-tomato, cucumber and grape in Japan. These robots mainly consist of manipulators, end-effectors, visual sensors and traveling devices. These mechanisms of the robot components were developed based on the physical properties of the work objects. The robots must work automatically by themselves in greenhouses or fields, since we are considering for one operator to tend several robots in the production system. The system is modeled after Japanese agriculture which is commonly seen to produce many kinds of crops in greenhouses and in many small fields intensively. Bioproduction in space is somewhat similar to the agricultural system in Japan, because few operators have to work in a small space. Employing robots for bioproduction in space is considered desirable in near future. The following is a description of the harvesting robots.

Robotic-assisted laparoscopic adrenalectomy.

INTRODUCTION: Remote robotic telemanipulators have been recently used in performing laparoscopic urologic procedures, both in the laboratory and in clinical practice. We present, to our knowledge, the initial 2 cases of robotic-assisted laparoscopic adrenalectomy in humans. TECHNICAL CONSIDERATIONS: Robotic-assisted laparoscopic adrenalectomy (one right, one left) was performed in 2 patients with an adrenal tumor (one nonfunctional, one pheochromocytoma). Patient age was 81 and 47 years, and tumor size was 4.5 and 3 cm, respectively. Both cases were performed transperitoneally using the da Vinci Robotic Surgical System. Robotic-assisted laparoscopic adrenalectomy was successful in both cases without conversion to conventional laparoscopy or open surgery. The operative time was 110 and 165 minutes, the blood loss was 50 and 100 mL, and the hospital stay was 2 and 3 days. No intraoperative or postoperative complications occurred. CONCLUSIONS: Robotic-assisted laparoscopic adrenalectomy is technically feasible. With increasing experience and refinement in the technology, the role of robotics in urologic laparoscopy is likely to expand.

Early experience with robotic technology for thoracoscopic surgery.

OBJECTIVE: Recently, robots have been introduced into surgical procedures in an attempt to facilitate surgical performance. The purpose of this study was to develop a technique to perform thoracoscopic lung resection using a telemanipulation system. METHODS: We have used a robotic system to perform thoracoscopic surgery in 12 cases: five lobectomies, three tumor enucleations, three excisions and one bulla stitching completed with fibrin glue for spontaneous pneumothorax. The operations were performed using the Intuitive Microsurgical system (Da Vinci System) through three ports and, a fourth space 'service entrance' incision, in the major lung resection. RESULTS: Three procedures begun with the robotic technique were completed by a minimal thoracotomy. No technical operative mishaps were associated with the manoeuvres of robotic arms. In all manoeuvres (up, down, insertion, extraction, etc.), the robotic arms moved appropriately in the favorable operative fields. All patients tolerated the procedure well and the post-operative course was satisfactory, requiring few analgesics. CONCLUSIONS: Although further studies on robotically assisted procedures are needed to clarify the clinical feasibility of this procedure, the results in our cases are encouraging. We believe that thoracoscopic procedures using a robotic manipulation system may be technically feasible in selected cases and in the hands of experienced thoracic surgeons.

Advanced thoracoscopic procedures are facilitated by computer-aided robotic technology.

OBJECTIVE: Computer (robotic) enhancement has been used to facilitate simple thoracoscopic procedures such as internal mammary artery (IMA) mobilization. This report describes the use of robotic technology in advanced thoracoscopic procedures. METHODS: Ten patients underwent advanced thoracoscopic procedures utilizing the Da Vinci robotic surgical system (Intuitive Surgical, Mountain View, CA) at our institution. RESULTS: Patients 1-6 underwent endoscopic phrenic nerve mobilization with insertion of phrenic nerve pacemakers. The indications were quadriplegia (n=2), central hypoventilation syndrome (n=2), and intractable hiccups (n=2). Three 1-cm incisions were made to access each hemithorax. Patients 7 and 8 underwent robotically assisted resection of posterior mediastinal masses. Patient 9 underwent robotically assisted thoracoscopic left lower lobectomy for a lung mass. Patient 10 underwent robotically assisted left ventricular lead placement for biventricular pacing for heart failure. CONCLUSIONS: Robotic technology can be used to perform advanced intrathoracic maneuvers thoracoscopically. The increased visualization and instrument dexterity afforded by this technology may facilitate the development of minimally invasive thoracic approaches that were previously not feasible.

Robotic-assisted esophagoesophagostomy.

BACKGROUND/PURPOSE: Minimally invasive repair of esophageal atresia has been described but remains technically challenging. Robotic surgical systems address many of these technical challenges. The purpose of this study was to develop the procedure for and evaluate the technical feasibility of performing a robotic-assisted esophagoesophagostomy using the Zeus Robotic Surgical System. METHODS: Esophagoesophagostomy was performed in 10 piglets using thoracoscopic (control, n = 5) and robotic-assisted (Zeus, experimental, n = 5) approaches. An interrupted esophageal anastomosis using intracorporeal knot tying techniques was performed and evaluated for leak, narrowing, caliber, and mucosal approximation. Anesthesia, operative, anastomotic, and robotic set-up times were recorded as was the number of stitches used. RESULTS: All 10 anastomoses were patent with no narrowing and with excellent mucosal approximation. One anastomosis in the control group had a small leak. There was no statistically significant difference between the groups for the parameters measured. Weight (kg): control (C), 6.4 +/- 0.8; experimental (E), 6.3 +/- 1.0, P =.08. Times (min): anesthesia, C-124 +/- 25, E-151 +/- 20, P =.09; operative, C-97 +/- 21, E-131 +/- 27, P =.06; anastomotic, C-89 +/- 20, E-125 +/- 34, P =.08; robotic set-up, C-6.4 +/- 9.3, E-15.6 +/- 20, P = 0.13. Stitches (No.): C-11.8 +/- 0.8, E-12.0 +/- 1.2, P =.7. Caliber (French):C-18F-5; E-18F-4, 14F-1. CONCLUSION: Robotic-assisted esophagoesophagostomy is technically feasible and offers an alternative approach to thoracoscopic repair of esophageal atresia.

Application of robotics in congenital cardiac surgery.

Over the past 5 years, robotic systems that combine advanced endoscopic imaging with computer-enhanced instrument control have been used for both coronary revascularization and intracardiac procedures in adults. In addition, endoscope positioning systems and articulated instruments with a robotic wrist mechanism have further expanded the potential applications for robotics in cardiac surgery. In pediatric cardiac surgery, potential applications can be divided into simple scope manipulation versus the use of 3-dimensional imaging and a robotic wrist for dissection and reconstruction. A voice-controlled robotic arm for scope manipulation can facilitate current pediatric thoracoscopic procedures such as ligation of patent ductus arteriosus and division of vascular rings. By using an advanced imaging system along with a robotic wrist, more complex extracardiac and even intracardiac procedures can be performed in children. Examples include coarctation repair, septal defect repair, and mitral or tricuspid valvuloplasty. Furthermore, with adequate intracardiac imaging, a robot-assisted off-pump approach to intracardiac pathology is conceivable. New real-time 3-dimensional echocardiography now offers sufficient resolution to enable such procedures, while the addition of instrument tracking, haptic feedback, and novel tissue fixation devices can facilitate safe and reliable intracardiac repair without extracorporeal circulation.

[Mobile autonomous robots-Possibilities and limits].

Besides industrial robots, which today are firmly established in production processes, service robots are becoming more and more important. They shall provide services for humans in different areas of their professional and everyday environment including medicine. Most of these service robots are mobile which requires an intelligent autonomous behaviour. After characterising the different kinds of robots the relevant paradigms of intelligent autonomous behaviour for mobile robots are critically discussed in this paper and illustrated by three concrete examples of robots realized in Lübeck. In addition a short survey of actual kinds of surgical robots as well as an outlook to future developments is given.

From wired to wireless: a miniature robot for intestinal inspection.

Increasingly more robots are used for various medical purposes, one of which is for intestinal inspection. A prototype robotic endoscope is presented along with a locomotion mechanism and relative experiment. Image, pH, pressure and temperature, etc. can be measured by the robot, which is very helpful in diagnoses. A wired robot will be replaced by a wireless robot because it is not comfortable for subjects and the wired robot cannot advance further into the small intestine because of too many folds and projections in the intestine. Key obstacles of the future wireless robot for intestinal inspection are discussed in detail and a reversed tracking method is provided.

Conformal intensity-modulated radiotherapy (IMRT) delivered by robotic linac--testing IMRT to the limit?

In this paper it is proposed that intensity-modulated radiotherapy (IMRT) could be delivered optimally by a short-length linac mounted on a robotic arm. The robot would allow the linac to 'plant' narrow pencils of photon radiation with any orientation (excluding zones within which the linac and couch might collide) relative to the planning target volume (PTV). The treatment is specified by the trajectory of the robot and by the number of monitor units (MUs) delivered at each robotic orientation. An inverse-planning method to determine the optimum robotic trajectory is presented. It is shown that for complex PTVs, specifically those with concavities in their outline, the conformality of the treatment is improved by the use of a complex trajectory in comparison with a less complex constrained trajectory and this improvement is quantified. It is concluded that robotic linac delivery would lead to a great flexibility in those IMRT treatments requiring very complicated dose distributions with complex 3D shapes. However, even using very fast computers, the goal of determining whether robotic linac delivery is the ultimate IMRT cannot be conclusively reached at present.
