Provide an effective structure for the robot to have moderate warmth.The robot 100 comprises a frame 500, a skin 502 covering the frame 500, a heat source for heating the fluid, and a pressurizing portion for pressurizing the space 504 surrounded by the frame 500. When the space 504 is pressurized, the heated fluid flows out of the space 504. Fluid flowing from the space 504 forms a fluid layer 506 inside the skin 502 covering the frame 500.
