Robot Arm Tastes With Engineered Bacteria (IMAGE) University of California - Davis Caption This robotic gripping arm uses engineered bacteria in wells in its fingers to 'taste' for a specific chemical before deciding whether to pick up the ball and put it in the bath. The system was developed by engineers at UC Davis and Carnegie Mellon University.
