What's the best way to build a tray for your robot

I used four L brackets and lexan in between to make my tray and I was wondering if theirs other ways to build a tray that is more efficient and easy to make extendable?

Do you have a picture?

I used c channel with lexan in between. It’s kinda heavy though, I might rebuild it later. Or just make the 3rd stage out of metal only,

I use aluminum 2x2 L channels. I have a 3 or 5 by c channel on the ends of the 1st and 4th stage to have perfect straightness.

No but essentially it’s the same as having c channels in between just with lexan

I’ve seen methods that use angles or c channels. the advantages of angles are that they angles can actually help support the bottom of the cubes, while c channels require some sort of backing. but really both work, and its up to builder preference.

the real question is what is the best way to make the joints between stages?

I’d say Angels are better. One of the teams I know used all steel angles, and their tray is at least half as light as mine, and I made mine out of aluminum c channels

how is this possible? angles weigh about the same as c channels

I dont know. But when I lifted the two, theirs was definitely 100% lighter.
Unless of course, I was tripping. I guess I was tripping :confused:
