# Rope climbing robot

Hey guys I have a freaking project that requires me to build a rope climbing robot that cannot be powered by chemical based. Basically no batteries as such are required.

Some background info about the scale and expected complexity of the project will be good to have. Right now I have no clue if you mean just a spring-loaded toy that'll pull on 10 cm of sewing thread, or something like the space elevator climber challenge.

Simplest thing that comes to mind: Two connected rollers with rubber bands inside, which you wind up.
