Robot combat is a hobby in which two or more custom-built machines use varied methods of destroying or disabling the other. As of today, in most cases these machines are remote-controlled vehicles rather than autonomous robots, although there are exceptions, particularly in the field of robot-sumo.
Robot combat enjoyed a period of mainstream exposure in the late 1990s and early 2000s when several television shows broadcast the robot fights. Either the public or the TV network administrators lost interest, and the shows dropped from the airwaves. The most well-known of these shows were Battlebots, Robot Wars, and Robotica. Although the mainstream was lost after the cancellation of those shows, robot combat has a large dedicated cult following and there are still dozens of smaller competitions around the UK, USA and in other countries every year. Combat robots have received mention in the press and entertainment shows from time to time as well. In the summer of 2015, the American television network ABC aired a brief sixth season of Battlebots.
