The Wide-mouthed Frog is a rubber powered pantograph mechanism entered in the 2001 Technogames 'high jump' contest.
He was built by Adrian Marshall and his family for BBC2's Technogames, an 'Olympics for robots' competition broadcast in March 2001
.
The Wide-mouthed frog was designed to be as simple as possible but to achieve maximum performance by use of appropriate materials and attention to detail.
