Yeah i wanted to build a pusher but with the skirts to ride along the ground and a big fan to pull it into the floor. Thank you for the drawing it's very much appreciated, I realise i need to up my game with robot building as people watch my thread and if we're trying to draw people in we need to set the example as the ones who have been competing for a while. I want to move up to featherweight and have a 4x4 drive train picked out that I don't think any one has used yet, but feel that sometimes making a robot invert able limits you to the usual brick designs.

i wanted to build something interesting so was thinking well how do you fight wedges without being invertable.
