Re: Programmers on the Drive Team

Our driver last year (still TBD this year) is the captain of programming this year. We have a very simple robot (4 actuators: H drive plus lift). He didn't feel that we needed to do very much with the slew driving; we have an arcade drive on our tank wheels and another joystick for strafing.

However, with no active intake and less than 1/4" tolerance to grab the side of the totes, pickup of game pieces takes a long time if being controlled from a distance away behind the polycarbonate. In addition to a camera which will both provide a driver feed and do some automated tote-finding, we have installed five sensors on the lift (four limit switches and an encoder), two rangefinders (distance to game piece or wall left and right), and four touch sensors (two curb feelers to find the scoring platform, and two on the lift face so we know wen we've touched a tote at both left and right ends). The practice 'bot is alternating between drive sessions and programming sessions to semi-automate pickup, stacking, and scoring motions.
