The present invention provides a robot capable of alleviating an impact when it comes into contact with a contact object and suppressing an increase in the internal temperature of the robot. A robot includes a movable part having a first internal space, a shock-absorbing section disposed outside the movable part, and having a second internal space, and a state switching section capable of switching between a first state of supplying a fluid from a fluid supply source to the first internal space and a second state of supplying the fluid from the fluid supply source to the second internal space.Further, the state switching section includes a first flow channel adapted to supply the fluid from the fluid supply source to the first internal space, a second flow channel adapted to supply the fluid from the fluid supply source to the second internal space, and a valve capable of adjusting opening/closing degrees of each of the first flow channel and the second flow channel.
