Dual-Arm In-Hand Manipulation Using Visual Feedback

摘要

In this work, we address the problem of executing in-hand manipulation based on visual input. Given an initial grasp, the robot has to change its grasp configuration without releasing the object. We propose a method for in-hand manipulation planning and execution based on information on the object's shape using a dual-arm robot. From the available information on the object, which can be a complete point cloud but also partial data, our method plans a sequence of rotations and translations to reconfigure the object's pose. This sequence is executed using non-prehensile pushes defined as relative motions between the two robot arms.
