When you said you plan to use wiimote did you mean as the gyro or as a controller? After I looked st this on paper if using the gyros I mentioned you should be able to drive it easily .... not too fast though

As a controller... I was thinking I could use the remote to "input a value" that would over come the gyro...to allow both steering, if x, and motion, if y.

@CRich yes once the gyro is calibrated the bot will fight to stay level until it gets a servo input and it will start moving that direction. Using a wii mote would be cool though. Show it off to your friends. Maybe make a maze and get your friends to try and navigate uniball bot through the maze lol.

Haha, alright. I'll put up some pics when it's done

@jstarne1 I've got two of the gyros on the wat! You said you drew it out, does that mean a schematic? Being that this is my first solo build, is there any chance you would share that me?

Humm, found this thread :-) and was thinking about adding a gyro or two to my biped. So I started experimenting with a GWS PG-03 I had laying from heli stuff. If for example, I put the gyro in series with one of the hip servos, the idea is when bot falls forward hip rotates back to keep CG (upper torso) in line. Seems to work for that side, but what about the other hip servo?

I thought about making one a slave to the other in EZB, but since the gyro feeback is outside of the EZB control, the second / slave servo is unaware of the correction, since it does not get a position feedback from the master.

Do I really need a gyro on each hip and keep them independant or is there away to do this in EZB?

Perhpas put the gyro on a seperate digital port and read in the values, than some how feed that as a corrective action to the servo pair?

TIA for any pointer.

I guess I should follow DJ's lead & go order a MMA7455 I2C device, and be patient for it to arrive.
