A bang-bang robot is a robot in which the motion of its parts is stopped by driving the moveable and extendible parts on each axis, or degree of freedom, against a stopping device.{{cite book|last=Hunt|first=V.

Similar types of robot are also called fixed-stop robots.{{cite book|title=Industrial Robotics Handbook|author=Hunt, V.D.|date=1983|publisher=Industrial Press|isbn=9780831111489|url=https://archive.org/details/industrialroboti0000hunt|url-access=registration|page=[https://archive.org/details/industrialroboti0000hunt/page/392 392]|accessdate=13 April 2015}}
