Heres a few images of the robot design we've created. The "jaws" are pneumatically operated and grab the ball loading it to the arm. When the arm is raised the ball is parallel with the over pass and the upper jaw launches it over. We originally were going to use 2 tread wheels and 2 mechanums but then opted for all mechanum. Questions comments or suggestion are appreciated.
