- keanzu 7y agoThe videos are great, consumes a lot less water than I imagined. Seems like most of the water is lost during the de-suction process, if they can scavenge that it could really cut the water consumption down nearly to zero.
- samstave 7y agoIf they have an additional ring around the outside of each cup, could they not suction the water back into the system? Also, wouldnt this be easily defeatable with small dowel protruding "thorns" - or dimples, as on a golf ball - maybe alternating convex/concave dimple patterns? or other ridges?
- pretty_bubbles 7y agoI don't think anyone is building suction robot proof buildings yet. It can barely climb the buildings we have now.
- pushpop 7y agoI don’t think it’s possible to build a suction cup (or in fact any climbing tool) which will work 100% of the time against any countermeasure. However this design does seem a significant step forward from existing suction cups.
- Tepix 7y agoSpeed is also an issue, the video is speed up 2x and the progress is still quite slow.
- simsla 7y agoSure, but this is only an initial prototype. I'm sure we could make it work faster/more efficient with a few more design iterations.
- logicallee 7y agoThis is very interesting. I wonder how the power use compares with achieving a similar effect using a vacuum pump.
- logicallee 7y agoEdit: I got downvoted. Is a powered vacuum pump not possible in this application? (Like putting a vacuum cleaner nozzle against the wall, possibly using a more powerful motor than usual, for more suction.) I think it's a fair question but maybe I'm way off base here.
- marcusjt 7y agoPresumably you were downvoted because your question suggests that you haven't actually read the article, which does mention how it compares to other powered suction (i.e. "vacuum pump") devices.
