A moving robot includes a first arm portion is coupled to a first joint on a side portion of a main robot body. The first arm portion has concave portion with an opening. A folding mechanism is accommodated in the concave portion. In the folding mechanism, a second arm portion is connected to the first arm via a second joint portion. A third arm portion is also connected to the second arm portion via a third joint portion. The first arm portion is rotated around the first joint to orient the opening in an upper direction. The second joint portion can be slid along the concave portion to take out the folding mechanism through the opening. The third arm portion can be rotated around the third joint portion to extend the third arm portion.
