This tiny super-precise robot can move 75 times per second

posted by Jason Kottke   Jan 22, 2018

Researchers at Harvard have developed a milliDelta robot that is very precise and moves very quickly. The video shows the robot moving so quickly (making circles up to 75 times per second) that the motion blurs, like Neo at the end of the first Matrix movie. From the description of a second video showing the milliDelta bot:

Our design is powered by three independently controlled piezoelectric bending actuators. At 15mm x 15mm x 20mm, it has a payload capacity of ~3x its mass. It can operate with precision down to ~5um, at frequencies up to 75Hz, and experience accelerations of ~22g.

This robot would kill at Track & Field on the NES.
