| Research Abstract |
Objective of this research is to develop a precise and fine sensing ability of manipulation task state by a multi-fingered robotic hand. Followings are the results of the research.
A method has been developed for active tactile sensing of shape of unknown surfaces using a miniature force/torque sensor mounted on by sliding motion of the fingertip based on position/force hybrid control. A method of surface reconstruction has been developed for an object with unknown curved surface using 3-D data of points on the surface and the surface normal information obtained by active tactile sensing.
A new method has been developed for detection and measurement of fingertip slip on a surface of a manipulated object in a multi-fingered precision manipulation with rolling contact. The method is based on the multi-sensor fusion of vision, joint-encoders of the fingers, and fingertip force/torque sensors. Tangential slip displacement of the fingertip contact is separated from the displacement by rolling motion of the fingertip.
Several planning methods of grasp for multi-fingered manipulation have been developed. Quality measures are introduced to select better grasp among possible candidates. The planner succeeded to generate a grasp which enables maximizing the range of motion of the grasped object.
Task model for the Peg-in-Hole task has been developed. The model is composed of a sequence of task state transition, motion primitives, and procedures for determining task state.
