We finished the Climber CAD and added it to the assembly of the robot.

Started cargo CAD: We played with the dimensions of the arm and found that an angle of 110 degrees got the arm as close as possible to the 48-inch line without crossing it. However, there was only 0.4 inches of clearance, and since the extrusion is one inch thick, we changed the angle to 108 degrees. This resulted in a clearance of more than 1 inch between the arm and the climber, as well as the arm and the 48-inch limit.
Then, we started putting all the extrusion together into a CAD model. Right now, the parts are mated, but there are no gussets yet. We also made a simple 20*10 backplate for the feeder mechanism. We will eventually add slots for the lexan guides and CAD weight holes, after the entire assembly gets pieced together.

Started hatch CAD: We started on the cart which will move the hatch mechanism from side to side.

We needed some help from mechanical subteam captains because we initially had trouble making sense of their drawings, especially that of the hatch. In making the Cargo arm, we also needed help mating extrusion at an angle of 108 degrees.

Continue on hatch and cargo CAD.
