Week 1 of the 2012 FRC Build Season is in the books, and we saw almost all the field elements finished, and an overhaul of our design at the end of the week.
As it looks now, our robot will be 35×27, long-and-narrow orientation. Four wheel drive, 8″ AndyMark wheels direct-driven off four CIMple boxes, mounted at the bottom of the chasiss.
As shown, the chassis is upside down; front side is to the right. The wheels will be mounted directly to the output shafts of the CIMple boxes. This arrangement allows a ball to pass through the front without contacting the CIMs. The wheels will not be collinear; we’re anxious to see how it will affect handling (if at all).
Above that will be an arm that swings out in front of the robot (as you look at the robot from the side, the arm’s path will form a circle) and scoops balls in to the frame. Inside the robot, there will be a vertical conveyor belt that leads up to a rotating pitching machine-style shooter. We’ll have a camera mounted on the turret, so we will be able to aim. We plan to make the conveyor long enough to hold 3 balls.
The arm will also allow us to tip the bridge to capture balls at the beginning of the match, or to climb on the bridge at the end of the match. The chassis will be high enough to be able to cross the beam without much difficulty.
We start again Tuesday, with a clear picture of our goal, and a lot of prototyping and design work ahead of us. Our goal is to have it functional by the end of Week 4. With the mentors we’ve been having and motivation of the students, we may reach that goal (weather allowing).
