Don't let that put you off, CAD is not essential in the design of a robot. It can be useful to play around with shapes and ideas before cutting any material, but it's just as easy to get some basic parts (motors, wheels, batteries) and lay them out in various combinations until you get to something that you feel happy with. The alternate CAD (cardboard-aided design) comes in extremely handing for making mock-ups of parts or body shapes.

The Sabretooth build diary has some good examples of cardboard and MDF prototypes to establish the body shape: http://www.fightingrobots.co.uk/thre...n-as-a-feather
