The description reads as follows;
The HiTechnic IR RC Car features the new HiTechnic Infrared Receiver. This sensor makes it easy for you to control your creations using a LEGO Power Functions Remote.
This model is based on the LEGO Mindstorms 1.0 set. It also requires a LEGO differential and that is not part of the Mindstorms set. If you do not have a LEGO differential, you can go to bricklink.com and search for "Gear Differential", the part number is 6573.
Features:
Remote control - Using the HiTechnic Infrared Receiver and LEGO Power Functions Remote
Steering uses a PID controller Both NXT-G and NXC sample programs implement a PID controller to steer to a specified target position.
Ackerman steering - Which means that it has a steering geometry so that in a turn the inside front wheel turns sharper than the outside wheel.
Geared up to differential - Geared up 3:5. The drive motor has a 40 tooth gear driving the 24 tooth side of the differential.
Building instructions and sample programs can be downloaded from www.hitechnic.com

nice,
Especially the use of the channel to select the power level
I did show the Hi-Technic shooter at LEGOWORLD 2009 in zwolle, and kids loved it.

I like the channel use too. I think the PID controller went way over my head... All the data wires confused me. :D
wow this makes me want to build robots even more. (i have been having a hard time building a robot recently becasue of moving and stuff). This sensor is actually what i was looking for for a long time :) Also good instructions :)
