Plenty of researchers are working to perfect robots that can collaborate with others to get tasks done. This video from zarrouk lab shows a BIG STAR robot collaborating with a child robot (RSTAR). These robots can reach locations that neither can reach on their own. The parent robot can recharge the battery of the smaller robot.
These robots are fitted with sensors and have automatic functions. They are designed at the Bio-inspired and Medical Robotics Lab at the Ben Gurion University of the Negev.
