Most gyro seem to like low gain settings on RN1 or else the dredded judders happen.

Question about accelerometers.

Accelerometers give a measure of the absolute angle of the Robot, the only adjustment you can make is to the physical orientation and mounting of the device. Common devices can measure angles in 2 or 3 axes (x,y) or (x,y,z).

Gyro's output a value that is proportional in magnitude to the rate at which the robot changes direction in a specific plane ie one axis only.

Setting up gyros on a robot seems like a fine art:

Besides zeroing your sero's correctly and deciding what servo's you want the gyro to adjust, there are three adjustments to be made:

Two on the gyro itself; Gain and Calibration setup, and one in the program with the GYROSENSE command.

This site helped me when I set up mine:

Good luck if you ever fit gyro's.... you are guaranteed to get the shakes in the beginning.

Long time no see.
My next newbie question.
What tool is used to change the accelerometers?
Or is it just adjusting the speed on the program itself.
Also.
How do you adjust a gyro, and for what reason?

P.S. BAUERMECH'S OPTIMIS KICKS ASS!
