End-effector position¶
End-effector position captures the translation of the relative frame transformation:
\Phi_\text{EffPos}(\boldsymbol{x}) = \boldsymbol{P}_A^B,
where \boldsymbol{P}_A^B is translational part of \boldsymbol{M}_A^B. The Jacobian of this task consists of the rows of the geometric Jacobian corresponding to the translation of the frame.
