Our mentors said it's impossible and we're gonna break our wings on our first try.
what do you think?
Nothing is impossible given enough time, weight, and money.

You'll have 150 lbs of robot 2+ feet out from your torsional point. So your ramps will need to support 300+ lb-feet of torsion. Not impossible, but not something to be undertaken lightly.

We were looking at holding to the vertical bar and flipping our robot upside down. At a lever arm of around 4 feet when the bot was horizontal, and considering the grab points on the bar would have been around 6 inches apart, you're lookin at over 1/2 ton of torsion / shear on the tower (and your gripper). Not something we felt comfortable engineering to.
