Re: pic: GUS Team 228's 2009 Robot Render

Another interesting bit of information about our 2009 robot: we only have six 1/4-20 screws on the entire robot*. Four are on the two pneumatic cylinders (because the rear pivot and clevis both use Ø.25 clearance hole), and two are on the trailer hitch. We used to almost exclusively use 1/4-20 due to it's availability at Home Depot, however a #10/32 screw is about 58.3% of the weight of a 1/4-20 screw. (That adds up fast when using steel fasteners).

There's a lot more interesting details, some visible in the render, some purposely suppressed, that will be released in due time. If you stop by our pit (at CTR or Championships), we'll have a lot more information about the interesting features of the robot, although most likely I won't be in the pits much due to event volunteering. Eventually I'll also have the students post the CAD models and drawings on the team website.


* Everything else is #10/32 socket cap head (most common) or button head, or #8/32 button head.

If you look at the full resolution (2560x1920) version of the render, you'll see two 3/4" bore x 4.00" stroke cylinders.

As for their function, that's up to you to figure out.
