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)!
