A mobile robot is an automatic machine that is capable of movement in a given environment.

A spying robot is an example of a mobile robot capable of movement in a given environment. Mobile robots have the capability to move around in their environment and are not fixed to one physical location. In contrast, industrial robots usually consist of a jointed arm (multi-linked manipulator) and gripper assembly (or end effector) that is attached to a fixed surface.

Mobile robots are a major focus of current research and almost every major university has one or more labs that focus on mobile robot research. Mobile robots are also found in industry, military and security environments. Domestic robots are consumer products, including entertainment robots and those that perform certain household tasks such as vacuuming or gardening.
