Back-Up Wheel Ideas

The main requirement needed of the third wheel is the need for it to move in multiple directions when the buggy turns (Ref Meeting 4). It needs to move easily with minimum drag on the motors moving the buggy. The biggest problem involved with this situation is the small size with which the wheel will be placed. Me, Mark and Anand got together and came up with three ideas.
We decided to go ahead with the idea involving a castor wheel that pivots 360 degrees and can be bolted to the buggy frame. Whilst conducting a search for a suitable wheel we found there to be a very restricted market for small castor wheels. To counter this problem we kept the 2 other original ideas as back-up, they are shown on the below sketch.
