Vertical climbing tank/rover
Just so I understand the concept...
The little tank is going to 'walk' up the tree past a certain level, then walk past the next sizable branch and then back down. Effectivley allowing you to hoist your climbing rope over the same branch and then asscend to that level... does that sound about right? Actually as soon as the little tank is above the said branch the engine could be shut down and it could be lowered back to the ground by its tether. right?
You might think about a slightly larger CL engine... just let it go full throttle the whole way... lighter/simpler carb
I think this would be doable... given a light enough 'tank' ... I would think that four driven wheels made from 4.5" circular saw blades would walk relatively well up the bark and be big enough to navigate the rough bark...
How long a climbing durration are we talking about? (will affect batter pack size, fuel tank size, etc.
Ok... juices are flowing now...
