Yeah they made it pretty nice this year, especially giving us those awesome photosensors.

My kids got a state machine together to run through the sequence of aligning the arm and driving up to the goal, and it was working but hard to keep perfectly aligned with the goal. Then we remembered the photosensors on the front and of the robot and were able to write a line tracking algorithm that just braked the wheel corresponding to the sensor that was tripped and we were in business. Compared to some of the autonomous challenges we've gotten before, this wasn't too bad.

Not to say it was easy, but it's certainly doable at an event.

I'm a FIRST relic of sorts, I remember when we used PBASIC and we got CH Flightsticks in the KoP. In my day we didn't have motorized carts, we pushed our robots uphill, both ways! (Houston 2003!)
