Re: Show off your machining!

We never did any official impact testing with it or stress analysis on the CAD file but i can say it's strong enough to withstand being sandwiched between two bots (that was our unofficial test, for fun ) without bending at all. Weight is the biggest advantage to using a uni-body chassis though, as pictured it weighed 7lbs compared to our 2013 robot's frame at 20lbs, which was made from C-channel and extruded aluminum. We've since ditched the uni-body chassis concept as we found it to limiting, but it's still a pretty piece to display.

Here it is compared to our 2013 chassis:
