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.
By optimizing the resonant frequencies of the system, the robot achieves speeds of up to 38.7 body lengths per second forward and 44 body lengths per second reverse , demonstrating superior performance to most current robots.

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.
