Today was … productive.IMG_1815

Since we got our strategy and design ratified by the team, we did some work on our chassis.IMG_1817

As you can see, our chassis is pretty small.  Final size is 24″W, 22″L, and in the range of 12″H (we still have a bit more CAD to do).  Here’s what we’ve completed so far:batman

And in real life:IMG_1819

Yup.  We’re doing 2WD.  Since our robot figures to be pretty light (<70 lbs) and our strategy doesn’t involve very much driving around, we decided to save weight and space and direct-drive some CIMple boxes.

We’re going to do a two-tiered electronics panel, with the battery and pneumatic tanks on the lower level; cRIO, PDB, router, jaguars, and victors on top.  We haven’t used pneumatics since 2010, so we’ve got a lot to (re)learn.

Maybe tomorrow and/or Saturday we’ll get more CAD done.  We still need to figure out the geometry of the arms and how exactly they’ll interface with the chassis.

  1. Just a quick comment about direct-driving CIMple box, you may find it’s geared way too high (there’s only a one-stage reduction). You may find the robot performs better with a chain reduction on the output, or use a two-stage reduction gearbox like the Toughbox Nano. Certainly using a sprocket in the design lets you change it afterwards if needed.
    Good luck with the climbing, and the new rule change…
