Can a Jacobian matrix be used to derive joint angles from end-effector linear and rotational velocity (without a filter)?
I have a 2-link, 2 degree of freedom robotic arm, that only measures linear acceleration at each link(through an accelerometer), and rotational velocity on each joint (through a gyroscope).
I know ...
