This part has me a bit. Irritated I guess is the word. The metal looked like it was 1/16 inch thick. (same as any Tetrix material) However It appeared that it was bent on a CNC break. Meaning its probably some grade of 5052 AL. I use 5052 AL on all my FRC robot designs as most parts need to be bent into shape. 1/16 inch AL with bends is plenty strong as long as you make the flanges long enough. Team 67 in FRC mind you does all 1/16 inch sheet metal on their drive train, and it holds up FINE. To say that the first time you get rammed your robot will fall apart is a bad conclusion/review, as if this does happen. Its not from the strength of the metal, its from the lack of engineering.

The metal looked like 1/32 inch to me (note it is held together with plastic pegs like lego), but its almost identical to VEX, I've used VEX and it does not preform well when there is contact involved, my team and I made that VEX bot as robust as we could and it took a great deal more work to get it competition ready, mostly because the kit it self is so flimsy. Say you take a VEX bot to the FTC world competition and it get rammed into a wall by a 52 lb robot (like ours this year), don't you think something would break? All I'm saying is the new matrix kit is less robust then Tetrix but has some cool pieces that could be useful on a FTC bot, although I wouldn't use it to build a FTC robot. As for your FRC robot, you wouldn't use 1/16 inch for the base of your robot, it would be used to more less to plate the robot.
