Parallel manipulators and robots constitute an advanced class of robotic systems where the end-effector is supported by several simultaneous kinematic chains. This architecture affords notable ...

image: Researchers have designed a low-cost, energy-efficient robotic hand that can grasp a range of objects – and not drop them – using just the movement of its wrist and the feeling in its ‘skin’.

A major challenge of robotic arms is the weight of the actuators, especially closer to the end of the arm. The long lever arm means more torque is required from the other actuators, and everything ...
