@Barin You can probably get decent use out of the stuff for hobbyist projects. You might be able to make a motor/sensor testing rig with it. You can give it to people when they're bored to build mini-robots with.
Use your imagination.
If you want to sell the stuff, your best bet would probably be to say the buyer must pick it up at Worlds (I might be willing to buy some if that is the case).
Unfortunately we did not qualify for worlds. Also we tried to use them for a classroom robotics project, however we could not get RobotC to work with them. We normally use PROS, but since PROS wasn't even around when PIC's were used in competition, we assumed it wouldn't work. I think the problem is that our RobotC version is too new. Do you know if PROS will work for this, or if there is a way to "un-update" RobotC if that's the problem?
