E-hm let me correct myself else it sounds like 16 drivers which is pricy :)

1 driver per motor. Power (or motor) driver is the thing that allows a controller board to adjust power output on a motor and consequently the speed of rotation.

Do you need it for a footbal game ?

A fun demo might be to set it down in the school's gymnasium and set up a number of waypoints it should hit autonomously. So nothing extraordinarily complex, but cool to do yourself. (My motivation here is mostly just cuz I think it would be cool, but the local school is considering doing some kind of programming robotics thing too and I know a guy with influence on that so I might pitch an idea to them as a student competition too)

I've been trying to turn my cat into a robot, but so far success eludes me.

Sonic and Tails keep destroying your lab?

I think the problem is I downloaded Cat 1.1 into its brain. I would try the latest Dog 2.6, but there isn't enough memory for it.

I accidentally turned my kitten into a fat cat. It was easy, I just kept the food bowl full for a year.

Perhaps the same strategy will work to transform your cat into a robot. Leave a bunch of transistors out each day and let nature take its course.
