Force 10

Force 10 was a robot designed by the Oakbank Robot Group. It had a front-mounted bulldozer blade and weighed 92 kilos, which meant it was over the weight limit. It is unknown whether this weight was reduced, and whether the robot was completed. It is also unclear which series the robot was aimed to enter in, but it is most likely Series 3 or Series 4 due to the weight limit. According to the team's website, the robot was "accepted", which could lead to the assumption that it was Series 3. Regardless, it never appeared on the show.
