Thanks! We're using Inventor 2016.

Doing something like turning your battery 90 degrees and moving it up against one side (taking the place of two of your motor controllers) will offset your CG a bit but it should not affect the performance of your robot to a significant degree. You could also mount pairs of the motor controllers on (new) vertical panels roughly above the motors and move the battery "forward", out from under the motor for the omni-wheel bar.
We will definitely fix this soon.

Don't insist on the layout of the components being symmetrical. The electrons won't care in this type of application.

Best of luck in Lubbock. Hope you make it to Lone Star some time.
The PDP, VRM, and 4 more Jaguars are located on a second panel underneath this one. They are all visible through the top panel for diagnostic purposes. We will try to rearrange to better fit the battery.

Also, remember there may be significant vertical forces as well as horizontal forces acting on the battery.
The battery was going to be secured by wrapping two industrial strength velcro straps around it in a cross formation and through slots in the plywood panel at the bottom.

Thank you all for the feedback! We greatly appreciate it!
