Detecting blindspots in colonoscopy by modelling curvature

ICRA 2021poster

Optical colonoscopy is the gold standard for colorectal cancer screening, however even under optimal conditions only 81% of the internal tissue is inspected, in part causing up to 22% of early adenomas to be missed. Blindspots commonly occur at acute bends where the camera’s view is blocked. 3D reco…

A Vision-Based Soft Somatosensory System for Distributed Pressure and Temperature Sensing

RA-L 2020

Emulating a human-like somatosensory system in instruments such as robotic hands and surgical grippers has the potential to revolutionize these domains. Using a combination of different sensing modalities is problematic due to the limited space and incompatibility of these sensing principles. Theref

Endoscope Force Generation and Intrinsic Sensing with Environmental Scaffolding

ICRA 2019poster

Endoscopic surgery is an increasingly popular alternative to laparoscopic techniques for many conditions, as the operation site can be reached without skin wounds. In many tasks, sufficient force generation is desired. As endoscopes must be highly flexible and slim, however, the force generation and…
