4.5.4 Pick & Place: Part 3

Course subject(s) Module 4. Manipulation

In this lecture, we will finish the build of a simple pick and place pipeline with different MoveGroup APIs.

Computing the linear motion:

compute_cartesian_path() API

  • Considers current Pose and the starting waypoint
  • Uses the waypoints and two other  arguments
  • Checks for collision
  • Outputs
      • Plan – the trajectory of joint angles and
      • A fraction of successful attempts

Update generated trajectory to the goal message and send it.

Lastly, use the set_named_target("R1Place") to move the robot to the object.

Run the script to see the robot in action.  This concludes the Pick & Place code demonstration.
