We’re just a week away from ICRA 2022! Our laboratory will present four papers at this year’s ICRA conference in Philadelphia. Two papers discuss our recent work on a distance-geometric formulation of inverse kinematics – by unifying the problem domain and co-domain, we avoid dealing with joint angle variables and are able to leverage key results from low-rank matrix completion theory and Riemannian optimization:

Our third paper investigates ways to efficiently recover the inertial parameters of manipulated objects, ensuring physically-plausible and accurate results even when operating in the typical cobot motion regime (i.e., slowly and safely):

Our fourth paper explores the use of low cost, slim, and lightweight barometric tactile sensors for slip detection. We take a data-driven, learning-based approach by training a TCN to reliably detect slip events from the raw barometer data stream. Cheap and useful for a wide range of applications:
