Once we had been put in to groups we pooled our resources and discussed ideas. With 8 people in the group it gave us a lot more scope to work on an idea discussing why somethings things would work better than others and if they were possible to build in the time scale allotted. The particular problem we had to over come was how to propel the machine forward, with the tree ideas consisting of fans, balloons and remote control. We all came to the conclusion balloons would be best as there cheap, easier to get hold of and light.

We all agreed the machine should have wheels and be made from a light material, we then went down to the skips to try and find resources, we ended up with plywood and polystyrene packaging. The idea then evolved into a square structure using the polystyrene and connecting wheels to it, with balloons attached to the back to push the machine forward.

From these ideas we then made a small model demonstrating how the machine would work with accompanying images as a visual aid to show how various parts would work.
