I'm a newbie so be kind to me. Do I have this right? You build an NXT robot w/ PF motors. The motors are hooked to their power supply as well as to the receiver via a cable. The IRLink is hooked to the NXT brick via cable. The NXT sends instructions to the IRLink, for ex: motors forward 50% power, the IRLink *beams* the instruction to the receiver, which then activates the motors.
Very close. The IRLink duplicates the function of the PF remote under control of the NXT. If I want the PF motor to go forward, I repeatedly have the IRLink send a "forward motor A" (or similar) command. One issue is that the IRLink doesn't continuously send the IR commands, and if the PF receiver doesn't get a signal, it stops the motors. So to run the motors, you must have a Loop in NXT-G that repeatedly sends a "motor forward" command from the IRLink.-- Brian Davis
So you could control the PF bulldozer or Dino with the NXT as well. So if you have to send a continuous signal from the NXT, would the PF motor work better for appendages rather than locomotion on the robot? Also, I was just reading the blog's Idea book about parallel sequences. Would that significantly slow down the processor?
Check out this blog entry back on 25 Sep 2007:http://thenxtstep.blogspot.com/2007/09/hitechnic-ir-link-sensor-for-mindstorms.htmlIt works pretty well - the signal doesn't have to be completely continuous. Also check out Philo's webpage on the PF system as well (also referenced in his blog).-- Brian Davis
