While safety should be considered in all aspects of robotic system design and operation, there are some additional provisions that need to be incorporated. Safety systems protect those operating near the vehicle as well as the vehicle itself. All robotic systems should incorporate an emergency stop system. This should be tied to the lowest level of vehicle control, making use of hardware only solutions whenever possible. The emergency stop should be controlled by on-vehicle stop buttons as well as an independent, wireless emergency stop system. Robotic systems should also have an emergency manual override system in place when a manned safety driver is present.
