Robots are already being used for bomb disposal and in situations dangerous to humans. The ANDROS Mark V-A1 is a robot that has already been used to kill a gunman in Dallas. The robot comes with a surveillance, stationary arm, and color camera. It also has multiple sensor and tool mounts to adapt to various missions. Its manipulator arm has 7 degrees of freedom. A 27-inch camera extender is also available.
As Bloomberg news explains, these robots are capable of inspecting suspicious packages and diffusing bombs. Their track allows for negotiating rough terrain.
