I've been clicking on the hitechnic irlink download page daily in anticipation :) I got one of those sensors cheap, really want to build a robot with 12 motors..

Amazing! I'm guessing your track system has more friction than the new coastedynamix one, causing the cart to go a bit slower (which seems more realistic to me).

It's the most efficient solution; sacrificing 1 sensor port to control 8 or more pf motors plus the 4 EV3 motor ports still available. Should make a nice robot :)

This IR transmitter allows NXT units to control PF IR receivers, I got one cheap and am waiting for hitechnic to make it EV3 compatible, which they said they are working on, but apparently it's a little more complex than the other sensors they make. http://www.hitechnic...ion&key=NIL1046

For cats, I assume

Ok so now it's easy for the next guy that runs into the same issue: "Let me tell you a little story about a guy who knew a guy at work..."

Make sure you either buy a new one from Mindsensors with EV3 firmware or have a NXT brick around to flash an older one to EV3... I bought one that had no EV3 fw, but I have no NXT brick to flash it...

Heh you beat me to it, I was planning the same thing. But yours is remote controlled, I want to build one that picks up trash from the floor autonomously :) The runfirst program is an interesting approach, I hadn't discovered that option yet to "remember" motor positions.
