Grid & Coordinate Robot: the 1st robot is a Grid & Coordinate Robot. It moves mainly on an X-Y axis and has efficient servomechanisms that result in clean stops.
Faulty Toy Robot: The 2nd robot is a Toy Robot. Movements on its hinges are jerky. A glitch in its system causes the robot to power down at which point it must be rebooted into the upright position.
