HiTechnic的NXT IR RC Car
HiTechnic的IR Receiver預定11/12會到貨。
HiTechnic公司也發表一台IR遙控車。
目前只有youtube的影片及敘述，控制程式及建構圖示應該會提供下載。
先轉貼敘述如下：
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.
這台車子可以使用樂高PF遙控器遙控。
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.
這台車子是使用NXT 1.0版本零件建構，需要LEGO的差速器(零件編號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控制前輪轉向，有NXT-G和NXC示範程式。
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，轉彎時，外側輪與內側輪偏轉角度不同，使車輛轉彎更順利。
（好像都是應用在賽車上，還請專家指教！
）
Geared up to differential - Geared up 3:5. The drive motor has a 40 tooth gear driving the 24 tooth side of the differential.
將40齒齒輪裝在馬達上，驅動24齒齒輪，有加速效果。
