Today we inventoried the 80-20 parts we already have and made progress on blueprints. In the process of doing so, we decided on the following dimensions:
27"x 37" with the top at a height of 12.5" (so this includes wheel radius)
(for the prototype, we'll still use the slightly large welded frame we have and mount an 80-20 frame of the right dimensions on top)
rotating arm "tower of power"--
44" from the top of the chassis to the height at which the sprocket is mounted (near the top of the arm-frame tower). We estimated a sprocket of max diameter 5", so presumably as much as 2.5" will extend beyond this height). This gives us an estimated robot height of 59" (12.5"+44"+2.5").
Don't forget to draw a blueprint (with dimensions and the 3 perspectives we talked about) of one of the grippers we want to prototype (or a variation on a design we've discussed that you think might work well)!
