Harvard U’s Microbot

Recently, Harvard University developed a tiny, high-speed, precision robot - called the milliDelta. This robot, which about the size of a penny, can have an extensive impact in several industries.

The milliDelta was created by using laser-micromachining - and it is a robot like no other. Reaching a velocity of 0.45m/s with an acceleration of 215 m/s2, the Delta robot is a high-speed robot. An origami-inspired product, it is starting to be applied in industrial factories and hospitals for intricate operations.

The milliDelta is a part of a chain of Delta robots, which roboticists progressively made smaller - finally reaching to the millimeter. These miniature speedsters, slightly bigger than a penny, are no larger than 15mm x 15 mm x 20 mm, and weigh around 400 mg, are becoming increasingly popular. In factories, these bots are able to complete the same time-consuming jobs (done by humans) within seconds. This previously chocolate packaging wonder has now started utilizing its quality of agility and productivity to help in factories, and even microsurgeries. Doctors have started utilizing this precision robot for surgeries - mainly eye surgery. Eye operations require extreme precision and care. When used, this microbot can substitute for a surgeon’s hands. Thus eliminating the slightest tremor of a surgeon's hand and lowering the possibility of an error during a surgical procedure.

The Delta’s agility comes from its creatively constructed shape - three legs in the shape of a triangle with a base connecting the legs. This robot’s light-weight structure, made from carbon fiber and kapton film, allows for it to run at high speeds. This robot gains its speed from piezoelectric actuators, which bend when there is voltage applied to them. Being able move at 75 hertz, this robot appears only as a blur on a camera. With its newly gained speed and with the precision of 5 micrometers, the milliDelta can do a lot for mankind, from working in manufacturers, to saving lives. Not only can this technology help industrial efficiency, but can also help in hospitals by helping perform microsurgeries.
