Marvin I

Spring 2008

Mountaineer Area RoboticS (MARS) - FRC 2614

As a member of MARS I had the opportunity to work on Marvin I which was designed to compete in the 2008 FIRST Robotics Competition (FRC) game: Overdrive. I worked primarily on the arm design, safety shielding, software, and as Marvin's co-pilot.

Game Description

Breakaway is played with two alliances of three teams each competing on a 27' x 54' field spanned in the center by a high "overpass." Four large "trackballs" start the match on top of the overpass. After capturing the trackballs the alliances score points by moving the trackballs in a counterclockwise direction around the field and throwing them over the top of the overpass. Bonus points are awarded if the trackballs are placed back on top of the overpass at the end of the game.

Technical Details

Two powered traction wheels in the front of the robot with two omni wheels in the rear (skid-steer configuration).
A robust extendable tower allows Marvin to consistently knock balls down off of the overpass.
Two single Degree of Freedom (DoF) arms are used to grip the trackball as it is moved around the field.
The arms can be controlled using pre-programmed set-points or miniature waldo arms on the control board.
Multiple autonomous modes are available.
