Miniature “Bio-Bots” Powered by Cardiac Cells

University of Illinois researchers have developed miniature “bio-bots” that walk without assistance.  These robots are made using only hydrogel, heart cells and a 3D printer. The idea behind the bio-bot is to replicate the elegant ways problems are solved in nature. The bot consists of a thin leg, which is covered with rat cardiac cells and rests on a sturdier supporting leg. The leg of the robot pulses when the cardiac cells are beating and causes the bio-bot to move forward. Researchers hope the new technology will be further developed in the future to improve drug screenings or chemical analysis.
