Team 2502 uses mostly 80-20 to construct our robot, while the sentiment that T-slot is heavy is correct that doesn't make it a bad building material necessarily. Our robot this year ended up at about 110 pounds with an 8 foot lift
Also included on the robot were a pair of RS775's and about 15 feet of chain. Tslot can be doable at light weights, you just have to keep in mind it is very strong. I (150 lbs) have stood on a 4 or 5" piece of cantilevered tslot bolted in the end by an end fastener and 1/4-20 screw without causing any damage. I am not familiar with square tubing but I would expect it to have different results.
I would have no qualms with supporting my weight on any of the bars on that frame.
This isn't an engineering fair and demonstration, it's FRC. Defense is part of the game. You can't expect a good FRC team to just sit there and get clobbered by a full-court shooter; they're going to engineer a solution to the problem. - Kevin Sevcik [more]
