Biological robots are made of human tissue, which can be used to implant

Robots do not have to be extremely large. Scientists at the University of Illinois, Berkeley, have created a robot that is just over 1cm in size, built on the backbone hydrogel printed from a 3D printer.

It is powered by a strand of skeletal muscle cells activated by an electric current. Previously, scientists created a biological robot with a heart tissue but could not control it. Biomarkers created from muscle cells can be activated with electrical impulses and scientists can manipulate it to "walk" at different speeds by varying the frequency.

The scientists said that these biological robots could be used in medicine such as creating anatomical robots, or making detectors in a mobile environment, and even "programmable tissue engineering." " These robots can be implanted on the human body to neutralize toxins or to improve biological control systems.

"Our goal is to create autonomous sensors from these devices. For example, we want it to feel a specific chemical (toxins) and move toward it, then release substances to neutralize toxins " . Said lead researcher Rashid Bashir.
