Description

This block computes the Jacobian matrix for a robot object robot in the pose q and as expressed in the end-effector coordinate frame.

This block has one regular input. It represent the set of joint coordinates q and therefore the number of its elements must equal the number of robot's consituent links (n).

This block has one regular output.

You can specify as block parameter the robot model robot for which you want compute the Jacobian matrix in end-effector coordinate frame.

Dialog Box

• Robot object : robot object. It represents the robot model to be simulated. Note that this variable is a symbolic parameter which has to be defined in the context of the Scicos diagram, in order that it can be used.
