Chapter 40 — Mobility and Manipulation

A compliant underactuated hand for robust manipulation

This video introduces the iRobot-Harvard-Yale (iHY) Hand, an underactuated hand driven by five actuators which is capable of performing a wide range of grasping and in-hand repositioning tasks. This hand was designed to address the need for a durable, inexpensive, moderately dexterous hand suitable for use on mobile robots. Particular emphasis is placed on the development of underactuated fingers that are capable of both firm power grasps and low-stiffness fingertip grasps, using only the compliant mechanics of the fingers.
