Support for towers?

I need some help working on my robot. Our robot has a few issues but the main issue I am worried about is our towers. When they are down low, like this:


they are fairly stable, though they still wobble back and forth slightly. When they are up high however, like this:


they are so incredibly unstable, and they sway back and forth. What I need help with is finding a way to support these towers so they don’t sway, so our programmer can have a consistent autonomous.

Any help?

P.S. Sorry about the sideways pictures. I’m in a rush and don’t have time to fix them.

Well, you could put some side beams EX. /I\ on each side give it support you could also use 1x20 bars and wrap around the bot to odd places that could help. Let me know if you need something more. PM me if you have to.
