Once we qualified for worlds via a Queen City Regional victory our team has been working hard to add a scaling mechanism. Three days in this is what we have. (Side note: we only have 5 lbs to work with.)

The video is from yesterday and today we added the motor and winch, pneumatic release, and hook. The climber actuates by two constant force coil springs and a regular spring.
See you in Saint Louis!
