How Did The Robot Buggies Come To Be:We were approached by the BBC to come up with some buggy designs inspired by Robot Wars. The buggies, unlike their larger Robot Wars counterparts, were to compete in non lethal competitions, such as football and capture the flag, which we did with Sir Killalot watching over proceedings. The buggies would need to be modified so that they were fit for playing the games, were aesthetically pleasing and be able to be controlled remotely. To be honest, they had us at Robot Wars. Challenge accepted! The time scales were very tight but luckily we have a skilled product designer on hand and direct access to Martin Woolley’s Bluetooth expertise, so between us we’d got one dreamt up, designed, built and tested (played with) within a few days.
What Were The Robot Buggy Design Challenges:
- Everything had to fit directly to our line following buggy.
- The finished buggies needed to have a Robot Wars theme.
- We needed to design two teams of buggies.
- When assembled the buggies needed to be robust enough to withstand regular impacts.
- The designs needed to be easy to produce and simple to assemble.
- We wanted it to be modular, ie made of parts fitted together so that design changes and/or personalising them was as easy as possible.
- We needed to make the buggies capable of herding a football.
- We needed to design a self righting flag and come up with a way for the buggies to grab it.
- We wanted to be able to control the buggies via Bluetooth and a hand held *Android device.
- We had a very tight timescale.
