This is a list of all non-heavyweight robots from the UK series of Robot Wars that competed in competitions for specific weight classes. Robots are categorised by the weight category in which they were entered, and their teams are listed in cases where a team has multiple separate entries. The list does not include appearances by non-heavyweight robots in the main competition from Series 1, which featured robots from various weight classes. However, the list does include heavyweight robots that were entered in the super heavyweight category, usually because the robot wasn't able to compete in the main heavyweight championship.
