1501, that bot was amazing. I couldn't help but stand and stare at it in your pit on Saturday. Any idea how much it can lift? Also, I'm curious as to how exactly you built it- even after power was cut off, it was still going up. How'd y'all do it?

Hi Jeremiah.

The mechcanial team says it can lift around 500 lbs. 480 lbs to be exact. It uses two air cylinders, and two gas springs with a 100 lbs rating. We use compressed air to compress the gas shocks down, and hold them down.

The lifting after power is cut is EASY....we use a double soleniod valve. The SMC one comes in the KOP. When the spool shifts in a double soleniod valve, the air changes state and keeps on lifting even after the electrical is cut from the soleniod on a double valve.

We used chrome moly tubing that was welded by a student and a mentor. It's the same tubing they build landing gears for airplanes and race care chassis. It's very strong. The whole frame only weighs I think around 34 lbs if I remember right. Each wing is moncoque and weighs about 11 lbs or so I think. I can't quite remember what the mechcanial team said so don't quote me on it.
