Scientists at Harvard University have created robots that use sensors, a few set of rules and environmental signals to build pyramids and other structures. The team was inspired by termites and their ability to work self-sufficiently without communication or a leader.
The robots are programmed to build 3D structures and then translated into a set of specific “traffic rules”. They move along a grid, climb a step and lift and put down bricks. Using sensors to detect obstacles, the robots react and know when the next brick needs to be laid or to climb one step higher.
