PROBLEM TO BE SOLVED: To provide a walking robot capable of easily getting up by itself even if it is fallen down while turning on the back by providing a means for changing posture of a barrel part from the turn-on-the-back condition to the turn-on-the-side condition at the time of fall-down in a walking robot provided with at least a head part, a barrel part and a leg part. SOLUTION: A robot 1 is formed into the two-leg walking type structure, and provided with a posture changing means 21 for changing posture of a barrel part 3 from the turn-on-the-back condition to the turn-on-the-side condition. Namely, roundness 22 such as a primary curved surface and polygonal surface is formed over from a back part 3a of the barrel part 3 to a right and a left side parts 3b. When the robot 1 is fallen down and the back part 3a of the barrel part 3 is grounded on a floor surface, the barrel part 3 is naturally turned in any one direction a1 of right and left or in the opposite direction by the roundness 22 and the polygonal surface so that the barrel part 3 is automatically changed from the turn-on-the-back posture to the turn-on-the-side posture. Thereafter, each two leg 4 and each arm 5 is operated so as to get up by itself in the fore and aft direction (c).
