'MilliDelta' Robot for Microsurgery, Microassembly and Micromanipulation

Because of their high precision and speed, Delta robots are used in many industrial processes like pick-and-place assemblies, machining, and food packaging. Delta robots use three individually controlled and lightweight arms that guide a platform to move fast and accurately in three directions. Now, Harvard researchers introduce a millimeter-scale delta robot, the 'milliDelta'. By integrating a microfabrication technique with high-performance composite materials that can incorporate flexural joints and bending actuators, the milliDelta can operate with high speed, force, and micrometer precision, which make it compatible with a range of micromanipulation tasks in manufacturing and medicine.
