A.m.p Robot. Segway Motion Bot.

 
#1

heres a bot i came across while searching today. It's self balancing is what caught my eye for for next build. check it out.





#2

Self balancing is very achievable with the EZ-B and EZ-Builder's native support for the MMA7455. There are a few examples of self balancing bots in the forums, on a smaller scale than what you found but the basic principals are the same.

#3

To me, balancing robots are both wonderous, being able to remain upright and evoking anxiety/thrill at the threat of falling to its destruction. This is akin to a tight rope walker! As in aameralis's examples I have to wonder how their creators build in armour and damage protection. I believe the DARPA robots can be pushed and kicked and still remain upright.

#4

My other concern is battery drain. Doesn't the battery drain faster since the motors are constantly working to maintain balance?

#5

Yes but lets be honest, how long do your batteries last currently? Even with a constant load on the batteries they will last a fair while (depending on the capacity of course)

#6

@ rich yes, but when my LeXI will be at a neutral stance, no battery drain, but a self balancing bot at a neutral stance is constantly working to maintain the position and stay erect. The only way I see a less drain would be to use dc motors. At rest they don't move as with my shoulders on leXI. Which is a positive thing in my eyes. servos are to needy.

#7

Pros and cons just like everything though. Pro is it looks awesome, con is it needs to constantly work to stay upright.

#8

@ rich. true. Lets see how my next build comes along.

You could always cheat and have a third (or even fourth) wheel hidden underneath for stability.

#10

talking to people who have built the two wheel balance bots they say that the current draw is fairly low until it actually moves the robot forward or backward. I would love to build one but I will cross that bridge next year when I'm more confident in building one I would consider worth while. Until then I would try something really small.
