Walkerbots (also known as Walkers or Walking Robots) are robots which use legs and/or feet as locomotion instead of traditional wheels or tracks. They first appeared in Robot Wars: The Second Wars, with Jim Struts competing in - and winning - the Reserve Rumble shown at the end of that series. The most successful walkerbot to date is Anarchy, which reached the Heat Final and won the 'Best Engineered' award in Series 6.
