- sandworm101 2y agoOr you could use wheels to transfer the load directly to the ground, bypassing the need for lifting motors.
- __MatrixMan__ 2y agoToo soon. Wheels aren't retro just yet.
- TeMPOraL 2y agoYes, but wheels don't work for arbitrary terrain, including long enough stretches going vertical or backwards[0], or liquid or gaseous terrain like rivers and large holes in the ground. -- [0] - think terrain looking like this: /----------- \--- \ ---------\
- sandworm101 2y ago> wheels don't work for arbitrary terrain You just need a bigger wheel.
- TeMPOraL 2y agoThat's why I said "arbitrary" - to mean "bigger than the wheel you have".
- sandworm101 2y agoThis is a cart being pushed by a person. So we can assume no terrain beyond what a person could reasonably step over.
- TeMPOraL 2y agoThis is a cart that can climb on its own - which means the person pushing it can climb independently. There's a class of conditions where this combo can work, and wheeled cart won't. Whether this class of conditions is something you'd encounter in practice (as opposed to adapting things to make an existing alternative usable) is another thing; I outlined some potential niche use-cases here[0]. -- [0] - https://news.ycombinator.com/item?id=41627135 https://news.ycombinator.com/item?id=41627135
- hn_throwaway_99 2y agoTerrain-following aerial drone tech already exists and has for a long time.
- TeMPOraL 2y agoSure, and this is terrain-following aerial drone tech that also keeps a cargo platform balanced, so why not use it to fly up/over the terrain rather than follow easy path?
- TeMPOraL 2y agoThat's the problem, though. Some Zefram Cochrane figures out how to work subspace, but all the profit from antigrav sleds will go to whoever won the patents for a pallet mounted on a quadcopter 40 years earlier. (Star Trek avoided this fate by having World War 3 happening in between today and warp drive.)
