Based on its micromechatronics technology, Epson has developed the uFR, Micro Flying Robot, claimed to be the world’s smallest flying prototype microbot. 

The uFR causes levitation by use of contra-rotating propellers powered by an ultra-thin, ultrasonic motor with a high power-weight ratio. It can be balanced in mid-air by means with a stabilising mechanism using a linear actuator. Furthermore, the essence of micromechatronics has been brought together in high-density mounting technology to minimise the size and weight of the circuitry’s control unit.

By developing the uFR, Epson has demonstrated the possibility of expanding the activity range of microrobots from two-dimensional space (the ground) to three-dimensional space (the air). The company now plans to test any problems related to the functional use of space by microrobots, and further concentrate its efforts on advancing its original micromechatronics technology and cultivating applications to meet future needs.
