Recently, a team of Chinese researchers unveiled a 15-millimeter microrobot that has broken speed records , surpassing cockroaches in agility and speed. This tiny robot , dubbed BHMbot-B , has been designed to move extremely efficiently, both forward and backward, by taking advantage of a vibration mode transition control system.
How does the BHMbot-B microrobot work?
The BHMbot-B microrobot employs an innovative system that allows it to quickly alternate between forward and backward movements, thanks to the precise synchronization of its electromagnetic actuators . These magnetic devices control the vibratory motion of the robot’s structure, giving it surprising maneuverability.

What makes the BHMbot-B unique is its ability to move in extremely tight spaces , which is essential for applications in medicine, rescue and exploration. Its compact size and high travel speed allow it to perform precise maneuvers in complex environments , where other larger robots would struggle. What’s more, this microrobot is not only fast, but also energy-efficient, thanks to its built-in battery and wireless control circuit.
The success of this microrobot opens new doors for the development of ultra-small robots in various technological areas. With its ability to perform fast and precise movements, the BHMbot-B could revolutionize robotics in sectors such as medicine, engineering and the exploration of inaccessible environments.
