Chapter 74 — Learning from Humans

Learning compliant motion from human demonstration II

This video shows how the right amount of stiffness at joint level can be taught by human demonstration to allow the robot to strike a match. The robot starts with high stiffness. This leads the robot to break the match. By tapping gently on the joint that requires a decrease in stiffness, the teacher can convey the need for stiffness to decrease. The tapping is recorded using the force sensors available in each joint of the KUKA Light Weight Robot 4++ used for this purpose. Reference: K. Kronander,A.
