IR transmitter for NXT

[Laui]

Hi there,

i already had a look around but didn't really find what i was looking for but maybe someone can help me out.

I would like to have a "car" fitted with PF IR reciever and pf motor to be remotely controlled with a nxt module.

The idea is to move this car on a fixed track depending to some conditions around, registrated by the nxt sensors. If i would use the nxt Brick to put it directly into the car, it would be to big.

So is there something like a IR transmitter for the NXT?

Thanks!

Hi,

This is probably the thing you need!

Control LEGO R/C trains and other motorized LEGO sets with the HiTechnic IRLink Sensor for the Mindstorms NXT. The IRLink uses Infrared signals to communicate with trains, Power Functions Motor controller and the Mindstorms RCX . Control the speed and direction of up to three LEGO R/C trains (7897 and 7898) and other sets including the new Technic Motorized Bulldozer (8275) and the Monster Dino (4958). The IRLink enables NXT programs to read values from RCX sensors and control motors connected to the RCX.

I have used Hitechnic sensors before and they are really good!

I think you are asking if there is a way to have the NXT in your hand and the car with its motors and sensors connect to the NXT via RF? is so there is no way to do this

Thanks for the replies.

Jim was already right, i'm just waiting for it to be shipped.

As soon as this project get's some shape i'll let you know.

Let us know the results!

That sensor (actuator) is high on my wish list. It's seems to provide an easy way to control (extra) motors.

I've been doing something similar with the IR Link for a couple of years - controlling a PF train or several on a linear track. The real problem is that its range is even less than the PF controller so a friend built me an IR repeater system to make it useable in display halls. Here's the Flickr video of my first attempts from two years ago.

Since my normal job took more time than i thought, the project didn't go much further yet...

The biggest point i'm struggeling about at the moment, is to put up a programm that does, what i want it to do ;)

Maybe it's me, but though i'm able to understand complex farm machinery and write cnc programms i'm not able understanding the mindstorm software. Or maybe i'm trying to put too much logic in it?

Anyone knows a good tutorial? Out of those that come with the programm, that tells what to do but not why?

Or many any advices for an different software to use, but still able to work with the IR Sensor?

I'll appreciate any help! ;)
