Had the last CCA Lego Robotics class last night. It went pretty well, we had one team that navigated a maze using just the optical sensor on the prebuilt robot, and the other team got pretty close. I've had a lot of fun with the class and I think the kids have too, and I think they've learned a lot.
The other thing I got to see last night was Brandon Heller's four legged walking robot Q actually walking. I used to bug him about how much time it was taking him to make it, but it's working now and it looks nice. He's planning to enter it in the CJRC this fall.
