When the crab stick was deflected, only the Y axis was used, and it acted as the throttle. When the crab stick was not deflected, the right stick acted as a single stick tank drive. There were also a few gimmicks that we used such as having a button to angle the crab slightly (helped with picking up against the wall) and some special logic to tank turn while the crab wheels were not centered (standard tank turn logic doesn't hold true when the wheels are turned because the robot will try to pull itself apart  ) |
Sorry about that. One of our mentors spoke with someone on your team about your crab drive, to get information about building our crab drive. Have you guys ever used, or tested out a 3 axis joystick for your crab drive? He was pretty convinced that a 3 axis joystick was the way to go after talking to you guys. The way he told us, the twist did the function that your left stick on the game pad did. Either he talked to the wrong person, or he confused himself.
