HiTechnic的IR Receiver定11/12到。

HiTechnic公司也表一台IR控。

目前只有youtube的影片及述，控制程式及建示提供下。

先述如下：

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.

台子可以使用高PF控器控。

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.

台子是使用NXT 1.0版本零件建，需要LEGO的差速器(零件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.

使用PID控制前向，有NXT-G和NXC示程式。

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.

使用Ackerman steering，，外偏角度不同，使更利。

（好像都是用在上，家指教！）

Geared up to differential - Geared up 3:5. The drive motor has a 40 tooth gear driving the 24 tooth side of the differential.

40在上，24，有加速效果。
