3-Motor Chassis
Building: Advanced


This robot base (chassis) uses two-motor drive and a pivoting castor wheel to allow it to turn easily on either carpet or hard floors, and it has the 3rd motor mounted low in the center, where it can used to drive something else that you attach to it.  This chassis is sturdy and level and can be used as a base for other projects.  No sample program is provided for the base alone, but you can try some simple movements using the "NXT Program" feature on the NXT brick or write your own programs.
