Created dimensions for the cargo. Dimensioned drawing on drive. 

Some notes:

• the first and kind of craziest part of this design is the "weak points" in the mechanism. Since the arm will be extended entirely past the bumpers, we need to prepare to be hit. Mike and I estimated around 1 solid hit per competition. Knowing this, we needed to figure out a way to make our mechanism both hard to break and shock absorbent. We went through a pretty long process of what ifs, and settled on the idea of designing in a "weak point" along the arm that swings the mechanism on the robot. This weak point, a joint between one stretch of arm and the intake/outtake would break before anything else on the robot if the intake/outtake is hit by a robot, absorbing the shock of the impact. So that the entire mechanism doesn't just fall off the robot, the extrusion would have some sort of cord running through it, holding the mechanism together in case of a break. 
• Hits:
  • worst case scenario: we are hit directly on the side of our intake. solution: design a breaking point
  • medium scenario: our roller shaft is hit. solution: replace shaft and wheels. it's stock, so it should not be difficult or expensive.
  • best case scenario: bumpers crash into our bumpers or side lexan
• Speaking of lexan, it may not be clear from the sketch, but there are two components made of lexan: the bottom of the intake/outtake is a sheet of lexan flush with the ground. In addition, on each edge of the 20" opening, there are strips of lexan to guide the ball towards the center of the mechanism
• The large rectangle in the center is a plate that connects to a limit switch, which senses when the ball is fully taken in, and stops the motor
• most of the structure is made of 1x1 square channel

figuring out how to make the structure impact resistant

Test drive atlaz and see how accuratley sam+marlow can intake cargo using our power cube intake
