Hi guys,
i'm looking forward to build something like this https://sites.google.com/site/onewheeledselfbalancing/
and i may look a bit stupid there but i need the gyroscop and i don't know the one i should buy and where...
I would use an arduino mega.

Thanks and sorry for my bad english, not my native language.

A standard 6DoF IMU would be a good choice, can then maintain orientation with DCM or quarternion method - there are
many forums about this, mainly on quadcopters, but the principle is the same - combine short-term gyro input and long-term accelerometer
input to estimate orientation.

For a simple one-axis balancing robot a single axis gyro and two-axis accelerometer is enough, but i think these skateboards
use tilt in the other axis as a control input for rounding bends?

Ok thanks for the answer, so this one as a gyro : http://www.seeedstudio.com/depot/grove-3axis-digital-gyro-p-750.html?cPath=144_146
and http://www.seeedstudio.com/depot/grove-3axis-digital-accelerometer15g-p-765.html?cPath=144_146 as accelerometer would be great, right ?

Thanks for the advice i'll check this forum

And for the steering i'm not sure but on 2 wheels, they use sensor but with one wheel it's kinda difficult and i think you can deal without.
