Abstract
A robotic manipulator wrist has one part 10 rotatable relative to the other part 12 of the wrist, and gear trains 16, 18, 20, operates to rotate the end effector shaft 14 when a brake 36 is applied to prevent relative movement between the two parts 10 and 12, and to rotate one part 10 relative to the other part 12 when a second brake 38 is applied to prevent relative movement between the end effector gear 18 and the intermediate gear 16.
