Canburglar Mechanisms

[JesseK]

We designed a can grabber last night in under 3.5 lbs. With a high flow valve, it could be under half a second to grab. With CAD, it's fairly easy to get right. I'll release the design once we fabricate it and know it works as-intended.

1.) 2D sketch the landfill & step, including totes/RB's
2.) Position robot in notional grabbing position in that sketch.
3.) Figure out where on your robot a can grabber would mount, then measure from that point to the center hole of the RC can
4.) Subtract that distance from 78" and that's the maximum height the pivot point can be at for the grabber.
5.) Add Pneumagics. Since the total rotation is ~90 degrees, the math for a bell crank is extremely simple.
6.) CAD mounts, fabricate them (CNC or any other plate-milling/cutting machine really helps, but isn't 100% necessary)
7.) Plan to get calibrations of angle on Thursday at the event
