Abstract
A robot includes a robot body, a pair of lift arms mounted pivotally on the robot body, a pair of leg support arms mounted pivotally on the lift arms, and a pair of wheeled leg assemblies mounted pivotally on each of the leg support arms. Each of the leg support arms is rotatable to turn one of the wheeled leg assemblies, which rests on the ground at the back of the other one of the wheeled leg assemblies, to a position in front of the other one of the wheeled leg assemblies, thereby moving forward the robot body. The lift arms are turnable upward or downward relative to the leg support arms to lift or lower the robot body.
