using mganets....

[DonRotolo]

If you want to use magnets as the *only* way of sticking the minibot to the pole - say, a drive wheel that's magnetic - I thought of two problems: First is that you'd need a powerful magnet (not easily done, and may be heavy); and second, all that force pulling the wheel to the pole may add some drag to the wheel (which makes everything slower. I think.). These problems may not really be true, and surely there are solutions to any problem.

If, instead, the magnets are just to 'help' the robot stick, then I think I'd prefer to lose the weight of the magnets and just make a better system of holding on to the pole.

So, my personal feeling is that magnets for the steel pole are a sub-optimal solution. But that's me, maybe I've missed something. (I often do).

(D'oh! Don't you just hate when you mis-spell an ordinary word in the thread title? Eh, it happens to us all.)
