Dara O'Briain and Angela Scanlon present the fourth heat of the robot fighting series. Competing in Group Battle 1 are Apollo, Kan-Opener, PP3D and Sweeney Todd, while Eruption, Sabretooth, Storm 2 and Terror Turtle clash in Group Battle 2. Another off-beat selection of 'bots include Apollo which is a powerful 'launcher' robot designed and built by a team of former holiday camp staff. Kan-Opener is a robot equipped with large piercing claws built by a father and son team. In another first for the show PP3D has been built using a lot of parts created using a 3D printer. A team of engineering students have designed an unusual 'future-tech' robot called Sweeney Todd which makes use of mecanum motion to move around the arena in any direction.
