Robo Doc was Team 101's original machine, which was entered in Series 2 of Robot Wars. It was sponsored by R Griggs and Co (manufacturer of Dr Martens boots) and cost £1000 to build. It reached the Arena Semi-Final stage in its heat, before being defeated by King Buxton, triggering the famous rivalry between King Buxton and Team 101's machines. Following Robo Doc's loss, Mike Franklin could not secure sponsorship for Series 3, and replaced RoboDoc with the famously inexpensive 101.
