Mini-robots Modeled on Insects May be Smallest, Lightest, Fastest Ever Developed
January 18, 2024

Introduction:

(Eurekalert) PULLMAN, Wash. — Two insect-like robots, a mini-bug and a water strider, developed at Washington State University, are the smallest, lightest and fastest fully functional micro-robots ever known to be created.

Such miniature robots could someday be used for work in areas such as artificial pollination, search and rescue, environmental monitoring, micro-fabrication or robotic-assisted surgery. Reporting on their work in the proceedings of the IEEE Robotics and Automation Society’s International Conference on Intelligent Robots and Systems, the mini-bug weighs in at eight milligrams while the water strider weighs 55 milligrams. Both can move at about six millimeters a second.

“That is fast compared to other micro-robots at this scale although it still lags behind their biological relatives,” said Conor Trygstad, a PhD student in the School of Mechanical and Materials Engineering and lead author on the work. An ant typically weighs up to five milligrams and can move at almost a meter per second.

The key to the tiny robots is their tiny actuators that make the robots move. Trygstad used a new fabrication technique to miniaturize the actuator down to less than a milligram, the smallest ever known to have been made.

“The actuators are the smallest and fastest ever developed for micro-robotics,” said Néstor O. Pérez-Arancibia, Flaherty Associate Professor in Engineering at WSU’s School of Mechanical and Materials Engineering who led the project.

A soft swimming robot without wires or batteries that can test for contaminants

A team of biomedical engineers and roboticists affiliated with multiple institutions across China has developed a type of small, soft robot that can swim through water and test for contaminants. In their paper published in the journal Science Advances, the team notes that the robot can be powered and controlled using radio waves.

Sending a robot into water-carrying pipes to test for pollutants could be helpful for city managers. Unfortunately, such robots are not available, leaving gaps in testing—though one team came close back in 2022 with the development of a twisted soft robot that could navigate mazes without human or computer guidance.

In this new study, the team in China developed a soft robot that can be placed into a water source and propelled and steered using the energy in radio waves. For now, they are calling it a miniaturized soft electromagnetic swimmer (SES).
