Nonlethal Weaponry
Robot security guards must be equipped to deal with people in possibly dangerous circumstances. Many security robots have been fitted with nonlethal weapons such as smoke or steam emitters and paintball guns. Robots currently cannot grapple physically with troublemakers or intruders, but the robots can alert human guards and deploy limited weaponry. Although, theoretically, robots can be fitted with guns and guns that fire electrified darts to stun or immobilize a person, this has given rise to ethical dilemmas.
