Abstract

Repetitive contact imaging uses a flexible whisker attached to a two axis robot to measure the shape of contacted objects. Assuming small deformations and rotations, the pitch axis decouples from yaw. The yaw axis, under PD control, sweeps periodically back and forth across the object while the pitch axis, under repetitive learning (RL) control, maintains a uniform contact force using load cell and encoder feedback. Once the RL controller converges, the 3D contact points can be determined using an elastica algorithm. The RL controller is proven stable based on a distributed parameter beam model and experimentally shown to provide stable performance with improved moment regulation when compared to PD control.
