GIRC (Graphical Interface for Robotic Control) is a ‘sketch’ written in Processing that enables user to draw a path file, save and reload, and transfer control codes to an Arduino-brained robot. The magnitudes of the turns and distances haven’t been calibrated yet, which is why the robot is still on blocks.

(. . . I have the uncomfortable feeling that the turns are in the wrong directions. Don’t comment me on that, I’ll figure it out! And BTW, sorry for the camera work, which cuts off on the right.)

Floor trials are starting soon, but maybe I first need to replace that furniture-wheel castor with the robot-ball castor that I bought.
