Atlas is a special humanoid robot by Boston Dynamics. We have covered it a bunch of times here in the past. These robots are going to get even smarter in the future. This video shows the robot walking over cinder blocks. It can detect partial footholds and adjust to each autonomously.
The robot uses its upper body momentum to keeps its balance. It lunges to prevent falling. The above video shows how this robot can walk over uneven terrains and maintain its balance.
