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

After just finishing several more renders, it appears I forgot to set some of the components in PhotoWorks, like the front chassis rail and the timing belt sprockets. Anyway, a different angle of the front of the robot.




P.S. Does anyone know a really good way to run real roller chain in SolidWorks (especially with different size sprockets)? I know you can do linear and circular patterns, but it's just so much easier to make a belt-like loop and override the mass properties to the correct weight (#25 pitch chain is .090 lbs/ft). I'll switch to real chain if an easy way exists.

We did a weigh-in of the practice robot (which is a lot more complete than our competition robot, as we send the practice robot to the Suffield Scrimmage) with most of the control system mounted (including CRIO, PD Board, Side Car, 2 Jags and 4 Victors) and the pneumatics compressor and two accumulators. We also put an entire 4'x8' sheet of polycarbonate to simulate the panels we have yet to cut out. We were missing some parts from the robot, but no more than about 10 pounds worth.

When we weighed in, we were at 99.5 pounds. Adding the other ten pounds of parts still to be installed, and we're still ten under. And the mounting for everything weighs almost nothing, as we're using 1/16" polycarbonate with 3/4" x 3/4" x 0.050"-wall aluminum angle with lots of rivets for making everything. Incredibly lightweight and strong.
