To provide a robot capable of acting while receiving an external force by contacting with an obstacle or other object in the outside, and relaxing a shock caused by the contact with the object in the outside world.

Contact pressure measurable sensors are dispersedly arranged in each part in a whole-body of the leg type moving robot for judging contact state to the outside world. Furthermore, modules by using an impact absorbing member are arranged in each part of the whole-body of the robot. Each of the modules covers over each part of the robot and has a function as an exterior component for protecting it from the shock. The module is formed detachably from the robot body and may include a battery for supplying electricity to a terminal member such as a sensor.
