In situations of bomb disposal, possible toxic hazards or other times that you would legitimately want to lessen the possibility of danger to an officer then robotics is a wonderful and much needed technology.
However, robotic technologies meets Taser™ and now we have a whole new set of parameters.
On 28 June, Taser International of Arizona announced plans to equip robots with stun guns. The US military already uses PackBot, made by iRobot of Massachusetts, to carry lethal weapons, but the new stun-capable robots could be used against civilians.
“The victim would have to receive shocks for longer, or repeatedly, to give police time to reach the scene and restrain them, which carries greater risk to their health,” warns non-lethal weapons researcher Neil Davison, of the University of Bradford, UK.
