Researchers from the University of Illinois recently announced they have developed a micro robot driven by skeletal muscle cells. This robot is composed of biological and mechanical parts, controlled by electric current and driven to walk by muscle extension & contraction.
In 2012, researchers developed a similar bio-robot with mouse’s cardiac cells but the cells contracted so frequently that the robot were not be well controlled. They used active skeletal muscle cells from human body in the new robot, bringing good controllability to the robot.
The researchers said they would continue the experiments of bio-robot, for example, testing the development of robot with other cells and researching how to control the movement direction of robot through different optical signals or chemical gradients.
Theoretically, this technology is very suitable for biochemical machines and the researchers are studying on how to use this technology to develop equipment for medical and environmental protection.
