Doc: dtheta unit should be \frac{rad}{s}

TLDR: Motor velocity (dtheta) should be documented in [1] as \frac{rad}{s}.

Hey,
while investigating the difference between motor position (theta) and joint position (q) I found that motor velocity (dtheta) unit was documented as rad but it supposed to be \frac{rad}{s} as it is the derivative.
How ever what's the difference to joint position/velocity? How do they correspond? What do I need them for?

* Motor velocity. Unit: \f$[rad]\f$

Hi, I'd also be interested in understanding the connection between motor/joint positions and velocities - did you get any update on this elsewhere by chance?
