a short amount of time, the system can choose between sounding an alarm, firing rubber bullets or engaging the target with other weapons. The system can also be overridden by an operator, who can also communicate via built-in microphone and audio system. Components and armaments Laser rangefinder: A type of rangefinder which calculates distance by measuring the time it takes for a laser pulse to reach a target and return the signal to its sender. Uncooled infrared thermographic camera: Detectors made of temperature-dependent pyroelectric and ferroelectric materials which form pixels that are read electronically thus forming images. Capable of seeing illumination down to 0.0008 lux (lumens per square meter). Infrared (IR) illuminator: A type of active night vision device (NVD) that allows images to be produced in light levels that near complete darkness. Mounted weapons (stock) Daewoo Precision Industries K3: 5.56 x 45-mm automatic light machine-gun with up to 1000 rounds/min rate of fire. Milkor MGL: A lightweight 40-mm multiple-grenade launcher. Controversy around the Samsung SGR-A1 The development of the Samsung SGR-A1 (and LAWS in general) has sparked considerable controversy regarding their effect on aggression between states, the issue on ethics of autonomous killing, and innocent killings through collateral damage. "Human in/over the loop" controversy A human-in-the-loop (HITL) system, if applied to the Samsung SGR-A1, would mean the weapon must wait for commands from a human operator before acting upon its targets. This contrasts with a human over the loop (HOTL) system, which would allow the Samsung SGR-A1 to autonomously engage targets while allowing for human intervention to stop it. Opposition groups against the use of the Samsung SGR-A1 and laws including the Committee on International Security and Arms Control and Human Rights Watch believe the Samsung SGR-A1 has HOTL capabilities, and would ultimately increase civilian casualties and lower the threshold for going to war. Primary arguments by anti-LAWS groups LAWS are unethical because humans are no longer involved in the act of killing, which absents morality from warfare by ultimately pitting a machine against a human. LAWS increase the risk of conflict and war by shifting risks from the nation's soldiers to machines, which distances civilians from war and thus changes how the military and government think about going to war. LAWS introduce a difficulty of assigning responsibility and accountability if scenarios including civilian casualties and violation of international law arise. Many of these opposing arguments, however, are based
