The main downside with this approach is that you can't turn on axis (so your
vehicle will no longer have a turning radius of 0).
When I first got the mindstorms I thought that it would be interesting to
have a vehicle which put down a foot, lifted itself up, turned, and put
itself back down. It would be possible to do this with two motors (either
using one for both lifting and driving or lifting and turning), but it
seemed like making the lifting foot work properly would be difficult
(although it might not be too bad if you used pnuematics).
