We built a cart that was supposed to be under 5 lbs and be able to carry a 10 lbs weight. It had to move a specified distance and return half way, under stored human energy. We chose to use the 10lbs weight as our potential energy storage. We had a height limit of 4 ft and used the full extent of that height as our storage method.
The three runs were:
- 50 ft forward -> 25 ft back - Perfect!
- 40 ft forward -> 20 ft back - We didn't quick make it, but were only off by a bit
- 30 ft forward -> 15 ft back - Perfect!
Once I can get it set up, I'll be posting my previous projects, as well as current project as additions to the blog, or my website: nick.lessley.googlepages.com
