dmethvin Posted September 9, 2015 Share Posted September 9, 2015 I was looking at this video: https://www.youtube.com/watch?v=iAtXdhUT3IMWhat if you built an EUC out of similar technology? Put a seat where the head is, then sit on it and it should be able to balance you in every direction, not just forwards and backwards. Link to comment Share on other sites More sharing options...
Donafello Posted September 9, 2015 Share Posted September 9, 2015 I guess you could but the way the head is held on that toy is from 2 small magnets. I don't know if you can get a magnet that would be reliable enough to hold a human or at least be safe. But I love the idea;) Link to comment Share on other sites More sharing options...
RidingInTheRain Posted September 9, 2015 Share Posted September 9, 2015 I've thought on this before, but I'd do it like this: Link to comment Share on other sites More sharing options...
Jag_Rip Posted September 9, 2015 Share Posted September 9, 2015 Biggest problem would be the very high center of mass while you sit on it. You need to have a counterweight inside the ball to make it work. So that chair on a ball will be 200kg with the rider. That probably wont ever feel safe when you are riding it faster than a person can walk.Make a chair on 3 balls and you get the same advantages in terms of mobility with none of the drawbacks like weight, but minus the coolness of a balancing feature.. I don't know if you can get a magnet that would be reliable enough to hold a human or at least be safe.Oh I do... its one of those things you really really really want, but dont have the slightest idea what to do with it... http://www.supermagnete.ch/eng/block-magnets-neodymium/block-magnet-110.6mm-x-89mm-x-19.5mm-neodymium-n45-epoxy-coating_Q-111-89-20-E Link to comment Share on other sites More sharing options...
dmethvin Posted September 10, 2015 Author Share Posted September 10, 2015 I have some neodymium magnets that are really strong for their size, and the large ones are outright dangerous to handle. I think that part could be worked out. Link to comment Share on other sites More sharing options...
Colestien Posted September 14, 2015 Share Posted September 14, 2015 Anyone seen the video on magnet motors, cool looking, but.......I have some neodymium magnets that are really strong for their size, and the large ones are outright dangerous to handle. I think that part could be worked out. Link to comment Share on other sites More sharing options...
PedalFaster Posted September 24, 2015 Share Posted September 24, 2015 Biggest problem would be the very high center of mass while you sit on it. You need to have a counterweight inside the ball to make it work.If only someone invented a vehicle that could work just fine by using an active control system to balance a high center of mass in a configuration which would otherwise be unstable...Oh, wait, did someone say this is a unicycle forum?In all seriousness, the issue isn't extending the unicycle control scheme to two axis, the issue is that balls don't tend to make very good wheels for imperfect surfaces or where there is grit like sand or gravel that can be picked up - and even worse if grease or magnets are involved to trap it.

Villac Posted October 10, 2015 Share Posted October 10, 2015 Here is a self contained system with a relatively high center of gravity that resists being tipped over. It appears to have good immersion protection as well: logrollinghttp://<iframe width="420" height="315" src="https://www.youtube.com/embed/OjUQTdtzRdc" frameborder="0" allowfullscreen></iframe> Link to comment Share on other sites More sharing options...
