ATP: Handing Over

With Scratch support completed, I’ve reached the end of what I wanted to achieve with the All-Terrain Pi. It’s been about 20 hours’ work overall — quicker than I expected, particularly getting the webcam streaming and creating the Scratch interface, which I thought would be a lot more painful than they were.

Just like the tank before it, it’s time to hand this toy over to a seven-year-old. We took it to the Constructorium hackerspace meeting at the library last Saturday and put it through its paces, first with the phone controls and then by programming it.

By the end of the afternoon the All-Terrain Pi was not only driving around (and bashing into things repeatedly), but the adults got a lesson in how to use Scratch as well!

Here’s the program we created to drive the robot around using keyboard input from Scratch:

As I said, that’s about it for what I originally set out to do. Some ideas we have come up with for activities with the robot, which we may or may not get around to, include:

Look forward to more robot-building soon!
