Ok, I'll give you a few tips. Depending on the game and your robot design, they may or may not apply though.

1> The KoP frame is very strong in the x and y directions but is flexible in the z (specifically twisting in pitch and roll). This could allow the frame to permanently deform with the 'vigorous interaction' with other robots (or this year ... falling). We usually box our frame. That strengthens it (and makes it heavier) and gives us a second deck to attach devices.

2> If you don't have to cantilever your drive system, don't. If you do, then calculate the twisting forces (especially side loads) and make sure your gearbox mounts can handle that.

3> If you use the c-channel, wherever you attach something put a wood block (or other support) into the c-channel. I've seen too many crushed and twisted c-channel frames in my day

The last one is just a guideline: When building something to survive impacts it must either be strong enough to withstand it or flexible enough to not care.
