Robotics Monday: NXT Holonomic Drive

Name of Model: NXT HolonĂ³mico

Details: Not too long ago, the Spanish-language LEGO Mindstorms NXT blog electricBricks wrote about holonomic robots. Holonomic driving systems are systems in which a vehicle has no turning radius - it can travel in direction without needing to have a "front" that is specifically powered. In the post I'm featuring today (as well as the video above), you can see a fully-functional, stable, and practical design for one made out of LEGO. While a three-wheeled version (as suggested in the earlier post) seems like a better idea at first glance, the difficulty of getting multi-directional wheels to work (and LEGO to fit into triangular shapes) makes it surprisingly complicated and often unsturdy. This one is fairly easy to build, with only turntables as a hard-to-find part you don't have enough of in the standard NXT kit.
