  Terminal 2: rosrun moveit_task_constructor_demo cartesian
  

  2. Same as above but with custom formating

  Run (Click to expand!)

  Terminal 1: roslaunch moveit_task_constructor_demo demo_cartesian2.launch
  

  Terminal 2: rosrun moveit_task_constructor_demo cartesian2
  

  3. Executing two task with differnt node name

  task execution not return problem -> resolved by using in built t.execute() and updating with recent PR #136

  Run

  Terminal 1: roslaunch moveit_task_constructor_demo demo3.launch
  

  Terminal 2: rosrun moveit_task_constructor_demo cartesian2

  Terminal 2: rosrun moveit_task_constructor_demo cartesian3
  

  4. Two arm panda executed simple different task

  (Cleaned) could plan but can execute -> resolved by commenting "capabilities" and "disable_capabilities" parameter in move_group.launch

  Run

  Terminal 1: roslaunch moveit_task_constructor_demo demo_cartesian4.launch
  

  Terminal 2: rosrun moveit_task_constructor_demo cartesian4
