Task Dynamics of Prior Training Influence Visual Force Estimation Ability During Teleoperation [PDF]
arXiv, 2020 The lack of haptic feedback in Robot-assisted Minimally Invasive Surgery (RMIS) is a potential barrier to safe tissue handling during surgery. Bayesian modeling theory suggests that surgeons with experience in open or laparoscopic surgery can develop priors of tissue stiffness that translate to better force estimation abilities during RMIS compared to ...

Elasticity Measurements of Expanded Foams using a Collaborative Robotic Arm [PDF]
arXiv, 2023 Medical applications of robots are increasingly popular to objectivise and speed up the execution of several types of diagnostic and therapeutic interventions. Particularly important is a class of diagnostic activities that require physical contact between the robotic tool and the human body, such as palpation examinations and ultrasound scans.

Proximally placed signal acquisition sensoric for robotic tissue tool interactions
Current Directions in Biomedical Engineering, 2018 Robotic surgeries are still limited with respect to the surgeon’s natural senses. The tactile sense is exceptional important in conventional clinical procedures. To identify critical structures inside the tissue, palpation is a commonly used technique in

Possible risk factors for keel bone damage in organic laying hens
Animal, 2019 Keel bone damage (KBD) in laying hens is an important welfare problem in both conventional and organic egg production systems. We aimed to identify possible risk factors for KBD in organic hens by analysing cross-sectional data of 107 flocks assessed in ...

Trajectory-Optimized Sensing for Active Search of Tissue Abnormalities in Robotic Surgery [PDF]
arXiv, 2017 In this work, we develop an approach for guiding robots to automatically localize and find the shapes of tumors and other stiff inclusions present in the anatomy. Our approach uses Gaussian processes to model the stiffness distribution and active learning to direct the palpation path of the robot.
