Angular velocities and rotation matrices
Let us assume I have an object O with axis $x_{O}$, $y_{O}$, $z_{O}$, with different orientation from the global frame S with $x_{S}$, $y_{S}$, $z_{S}$ (I don't care about the position).
Now I know ...

Gyro measurement to absolute angles
Let us assume we have a gyro that is perfectly aligned to a global frame ($X,Y,Z$).
From what I know the gyro data give me the angular rate with respect to the gyro axis ($x,y,z$). So let's say I ...

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 ...
