Suzanne Gill reports on an interesting design development to the traditional Delta robot. Also known as parallel-link robots, Delta robots have, for many years, provided a solution for high-speed, high-acceleration robotic applications. The traditional Delta design consists of three jointed arms connected to motors on a central hub base unit. Coordinated movement of the arms up and down from the base unit pushes the joints inward or outward, which moves the plate in the X, Y and Z axes, giving the robot a cylindrical work envelope.
