My good friend Henrik gave me a great idea, build a LEGO Skateboard / Hoverboard that uses Rotacaster Omni Directional wheels as its the year of Back to the Future. Here is a quick rough prototype of it. It is supporting my weight at 85KG. It uses 8 NXT's, 16 NXT motors and 8 Rotacaster wheels http://www.rotacaste...tic-wheels.html Next version to be stronger, and look cooler! I had another go after the filming had stopped and was great fun, until I fell off lol
