Fully Omnidirectional Compliance in Mobile Robots

In order to make unintentional physical interaction with robots safer for humans, we develop compliant control of an omnidirectional wheeled base using Drive-Torque sensor feedback. The movie below shows a fully holonomic mobile robot system which achieves compliant motion via sensor-based force control, improving over previous pseudo-omnidirectional mobile systems by being fully omnidirectional. It shows compliance and safe interaction in both the mobile system alone and as the base of a wheeled mobile manipulator style system.
