Design of a soft catheter for low-force and constrained surgery

IROS 2017poster

Surgeries involving interaction with soft tissue like the brain need to minimize shear and normal forces that can cause tissue damage or hemorrhage. Other surgeries require the ability to follow a complex, curved path, such as through an intestine or to a kidney stone. This paper presents a soft cat…

Linear actuator robots: Differential kinematics, controllability, and algorithms for locomotion and shape morphing

IROS 2017poster

We consider a class of robotic systems composed of high elongation linear actuators connected at universal joints. We derive the differential kinematics of such robots, and formalize concepts of controllability based on graph rigidity. Control methods are then developed for two separate applications…
