Little Neko finally got some paint tonight: Terra Verte. He's just doing a random walk, using the ultrasonic sensor to keep the brush at the canvas, and the accelerometer to stay upright. I'm hoping eventually that using a random walk and a canvas, Neko could learn how to address the canvas as an X-Y plane. Writing something like that isn't easy, but it's less tedious than hard coding all the different angles. I'm hoping I can get away without putting potentiometers at each joint.
