Simple… Post which type of lift design you think is best, it can be your teams or another’s. Feel free to post the same idea as someone else; I just want to see what other people are thinking! Keep this thread clean of bashing on other teams design please!

My choice...

I personally like my teams lift design the best (biased I know) We did a forklift style lift powered by two r550 bane bots motors through a cim-u-lator and a 12:1 reduction. Our lift is made of three layers of two 80/20 bars spaced an inch apart. The first and second stage go to the top of max starting spec (5ft), and the third stage simply is used to attach out grabber and slides freely on the second stage. Our lift is mounted in the dead center of our robot and our arm pivots 90 degrees and can pick tubes up off the ground. We can reach the top row +. We milled Delrin sliders to fit in the groves of our 80/20 and when all of the stages are engaged it only takes 15lbs of force to raise our lift. We used our lathe to turn our own pulleys and created a system to catch the rope incase it jumps a pulley keeping our friction low. We not only have a power up, but also a power down and a super simple tightening system. This allows our lift to be raised and lowered in well under 2 seconds without jumping pulleys. Being a student built and designed team, we are so proud of what we learned this year. Our mentor’s definitely guided us along the way, but us students are so proud of not only designing a solid robot, but also taking advantage of the new machines (mill and lathe) which our school got this year. We have made one of our best robot’s to date!
