"New IR RC Kart Sample Model"

"The HiTechnic IR RC Kart features the HiTechnic IR Receiver sensor. This sensor allows you to create NXT models that are controlled with a LEGO Power Functions Remote.

"This model is buildable with either a LEGO Mindstorms 1.0 or 2.0 set. The building instructions show 2.0 part colors and wheels but otherwise uses only parts available in both sets.

"This model also features the new HiTechnic Motor PID Block. The block makes it easy to have an NXT motor drive to a specific angle position. In this model the HT Motor PID block is used to control the steering motor. The block is used twice in the program, first it is used to initialize the steering motor by having it drive to both the left and right mechanical limits and then setting the zero position is the point in between these limits. Then inside the loop the desired steering angle is determined by the IR Receiver and then value is passed to the Set Point of the Motor PID Block.

"Building Instructions and Programs can be downloaded from http://www.hitechnic.com/models . The IRReceiver and the Motor PID blocks can be downloaded from http://www.hitechnic.com/downloads ."

Very nice cart! I love the wheel lift mechanism. I could hope to make this.
