Yun and Bachman used a legacy sensor combination for their paper, and gave appropriate empirical values for process noise variance D, gyro noise variance r_angvel and quaternion noise variance r_quats. The kalman() implementation hard-codes these parameters, as well as the arm movement time constant tau. Please make these tuning parameters more easily accessible: bring these up into the function call.
