Currently I am building a robots with 2 incremental encoders with a optical mice sensor. The reason to install a optical mice sensor is to provide better feedback when slippage happen on the encoders.
I wonder if I could apply a kalman filter to get a better distance feedback with these 2 kinds of sensors? Especially when the control input is unknown?(For example I push the car with my hand, but not applying a voltage to the motors)
I have read some examples to use kalman filter (gyro+accel / encoder+gps), either one of the variable used is in absolute measurement, while in my case, two feedbacks are dead-reckoning.
Any help is appreciated =] !!!!!
