indepentantly control multiple PF motors remotley

[SNIPE]

Hi,

If I had a model with an on-board battery & some motors with wheels attached, can I remotely and independently power some but not power others (turn some off and some on)?

I know there is a switch on the IR receiver for 4 input/output channels but this is impractical when just trying to drive remotely.

This can be wired or wireless but wireless would be better, can the Lego remotes tell the IR receiver to change channels which bypasses the switch on the receiver?

Or how about the NXT IR sensor connected to PF

You could power SOME of the Lego Power Functions motors if you had multiple PF Receivers and PF Remotes (clipped together, side-by-side). Each set of Receivers+Remotes would be set on a given PF Channel. There is no automatic way to get a PF Receiver to change channels. If you only had one PF Remote, you could select a different channel to get the other motors to run.

Read this NXTPrograms.com article on the "Power Functions Remote Control Sensor" for "...two ways to make a Power Functions IR Receiver act as a sensor for an NXT, so that you can build projects that combine the NXT with Power Functions parts and control both the Power Functions and NXT parts with the Power Functions IR Remote Control."

I think your topics might get replied to if you spell your titles correctly and Capitalize.

Anyway I think the only way that's going to happen is if you modify the circuitry or something.

Edit: Sorry, I didn't think about NXT.

I like to have 4 motors on but turn two off (one of the front and one of the rear motors)

when applied this makes the car turn.

For that you need two receivers and two remotes.

In case of M motors, you can attach two of them to each output of a receiver. In that case, you will need only one receiver, and steering will be similar to the steering of a bulldozer or a tank.

Like this you mean? http://www.eurobricks.com/forum/index.php?showtopic=82087

Only requires one v2 receiver (with L-motors) or one older receiver if you're using M-motors.

Ok cool, what about remotes?

I'll need two remotes for 4 PF M motors and 1 receiver.

I'd like to use the NXT receiver as its easier to mount and smaller is this possible , using the NXT to PF converter cable, it will be plugged into the PF 9V battery box., The NXT one could be plugged in first and the motors wiil be plugged in ontop of this.

yes, but this is my take on it, it will be lighter and simpler and of course have this steering thing, and can flip upside down while still driving.

I'm making a larger version with 4 RC buggy motors hopefully soon, this will have more features like a 'hatch' type roof where you go to enter the cabin, maybe mechanical steering (with a steering rack etc as well as this motor steering) and complex bodywork.
