Abstract
A running and working robot for performing a prescribed work while it runs includes a body with a running unit, and a working unit for working, and the body is coupled to the working unit by means of a coupling member with a buffer member. As a result, even when an excessive force or shock is given to the coupling portion between the working unit and the body, damage to the coupling portion can be prevented.
