Abstract
If an external force is applied to any one of the legs of a walking robot, or if the output-end gear provided in the leg stops rotating, the motor and gears for driving the leg are prevented from breaking. More specifically, the thigh section of the leg comprises a slip gear arranged in a column of gears. The slip gear slips in the direction opposite to the direction the slip gear is rotated with a force transmitted between an electric motor , i.e., drive means, and the thigh section , when this force becomes equal to or greater than a predetermined value.
