Can someone explain the advantage of a segway style robot, and why there seems to be more of them out there.
One point that immediately comes to mind is turning in place... you can do that fine with 4 wheels (only in a box config?) and 2 side-by-side wheels, but not with 3-wheels (unless you're talking omni wheels/mechanum drive)
I'm trying to design a robot which uses either a segway style (automatic stabilization) or a tricycle design.Can someone explain the advantage of a segway style robot, and why there seems to be more of them out there.
I assumed non-caster on the front (The word "tricycle" definitely put an image in my mind.),
I'm used to this sort of 3 wheel vehicle, which has horrible turning radius (Then the definition of turning in place can be bantered about, too)
As You know, segway type bots are dynamically balanced - that is the main advantage.
In other terms - no matter type of terrain, it will always try to compensate for temporal instability. If built well it does not matter for Your bot if it goes on nicely leveled terrace, climbs steep hill or goes the same hill down - stability of the bot will always be the same.
Secondly, thing is that such a bot always turns around its geometrical center, hence 0g while turning.
Thirdly, no matter what load You put on Your robot (load that would not crush Your bot, or exceed motor capabilities), or how disbalanced load is, self-balancer will always find perfect balance and execute 0g turns.
Most important thing (for DIYers) is the excitement You get when robot stands straight
