skill_cartesian_velocity
Track a desired velocity of tool_frame w.r.t. target_frame.
For Translation, target_frame specifies the translation axes. For Rotation, tool_frame specifies the pivot point. Specifying the rotation axes with target_frame does not fully work (see #356)

Parameters
Required parameters:
tool_frame : stringName of the tool frameaxes : csv:stringList of axes to apply velocities.Default: x, y, z, a, b, cvelocities : csv:floatVelocities in [m/s] or [rad/s].Default: 0.0, 0.0, 0.0, 0.0, 0.0, 0.0velocity_frame : stringDefines in which direction the robot will move.
Basic parameters:
robot : dictRobot that is controlled by the skill (only needs to be set at the application level).
Expert parameters:
skill_name : stringName of this skill. Must be locally unique.bounds : list:boundContains the bounds description(s).monitors : list:monitorContains the monitors of the skill that determine when the skill should terminate.transitions : list:transitionContains additional transitions to other states (skills), given an event name.scripts : list:scriptContains scripts that should be executed while the skill is active.
Hidden parameters:
collections : list:collectionContains the kinematic chains of the skill (feature, robot, object chains).Default: odict_keys([‘collection’, ‘target_to_tool’])loops : list:kinematic_loopContains the kinematic loop(s) that define the task to be solved.Default: odict_keys([‘kinematic_loop’])tasks : list:taskContains the task description(s).Default: odict_keys([‘velocity_feedforward’])target_frame : stringName of the target frame
