hello everybody , i m french and i read since few months this forum which is very interesting and well made .

I expect to buy a bioloid premium , just for my hobby , programming and building and community 's exchanges.

so now this is my question :

when i look around every robots , there are just two bots that have feedback informations i think : bioloids and robobuilder .

so , is there some body who use for the bioloid ,the curant feedback for walking ,and what is the action made for ?
does gyro or accelerometers give better work ?

thankyou for your answers

i have just seen that i had made a mistake i mean CURRENT , but i hope that it is not the mistake which stop the answers ???????

The AX-12 give you access to a value called "load." It's not the most precise data, but it is something. I don't think it is actually derived from current.

You really need both a gyro and an accelerometer to get an orientation of your robot. An accelerometer can give you an orientation value, but it is effected by translations. A gyro can give you the change in the orientation, but since it is relative the accumulated value will soon drift. If you combine both an accelerometer and a gyro you can take advantage of the strengths of both and quickly output a high quality orientation value.

thank you billyzelsnack for your answer

yes i think that gyro and accelerometers or force caps on the feets are better , but i thaught that dynamic walk could be used to andjust the gravity center when the robot walk with the load tork in every AX12.
the gravity center is not one fixed point , like a car which is accelerating the gravity center is going back .

Inverse kynematic if i don't do a mistake don't take inertial movements but just the wheights and positions ..............
