## 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.

 PhysOrg.com engineering news on PhysOrg.com >> Researchers use light projector and single-pixel detectors to create 3-D images>> GPS solution provides 3-minute tsunami alerts>> Single-pixel power: Scientists make 3-D images without a camera
 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. http://www.spaceward.org/elevator2010-pb
 We're basically required to build a robot that is non-chemically powered to climb a rope of 8mm thick to a height of approximately 1.5m

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

 hmm what if i use a pullback or wind-up motor... u think can climb better?

If you have one, you can try. But keep in mind that the weight counts. Rubber bands are light.
