Power Functions Motors

Post  OABB 4-H Lego Robots on Fri Aug 13, 2010 3:50 pm

It looks like you can plug a power functions motor into the NXT, but you need to use the NXT to RCX adapter cable and a Power Functions Extension cable, then plug the PF motor on to the extension cable. I think you give up any fine control of the PF motor(s) when you do this however.

Can someone that has tried this confirm/elaborate?

Power Functions Remote Control Sensor

Post  Team Shadowed Craters on Fri Aug 13, 2010 3:35 am

Ah, I did see that webpage http://www.nxtprograms.com/extra/PF_remote/index.html however it looks like those two examples are actually ways for the NXT to sense what the Power Functions IR Remote is doing. In the second example, the Power Functions Remote, not the NXT, is controlling the Power Functions motors. The NXT is using the old RCX rotation sensors to figure out which direction the Power Functions motors are turning and then displaying that info on the NXT screen. (The first example is a way to read the Power Functions IR Receiver via the NXT sensor ports.) Many people are looking for a way to control the NXT remotely so this provides such a method.

Is this interpretation correct, or am I misunderstanding the explanation?

Motors

There are cables available from LEGO that allow you to connect the old 9V RCX motors to the NXT. It looks like the #
LEGO® Power Functions Extension Wire Item #: 8886, will plug onto the old RCX motor connectors. I don't happen to have any of the extension wires to verify this.

http://www.nxtprograms.com/extra/PF_remote/index.html shows this in action.

Our robot just uses anti-gravity emitters to hover around the table.

We're only planning on using the regular 3 NXT motors in our robot, but we've seen images from some teams that suggest they're using NXT motors with Power Functions motors.

Not having any experience with Power Functions motors (not allowed in FLL I think), I'm not even sure how people are connecting them to be controlled by the NXT unit, and I thought it would be interesting to poll the teams.
