Rotraktor was a competitor robot that attempted to enter Series 4 of Robot Wars. It failed to qualify after losing its qualifier and being deemed 'boring' by one of the producers, compelling the team to build more 'visually interesting' robots for future series. They subsequently built and entered Barber-Ous for Series 5-7, as well as Office Party, which failed to qualify for Series 5. Both Barber-Ous and Office Party were built using parts from Rotraktor.
