import moveit_commander. This function does what you'd expect and moves files from one location to the other, as follows: import shutil shutil.move (old_path, new_path) Learn Data Science with shutil.move () works by first creating a copy of the file with the path defined by old_path and storing the copy in the new location, new_path. In MoveIt!, the primary user interface is through the MoveGroup class. You can ask RVIZ to visualize a plan (aka trajectory) for you. not use that function in this tutorial since it is 1 You will likely need to use a subparser: docs.python.org/2/library/argparse.html#sub-commands.

Start RViz and wait for everything to finish loading in the first shell: Now run the Python code directly in the other shell using rosrun. Sometimes for debugging it is useful to print the entire state of the Note in some instances you may need to make the python script executable: In RViz, we should be able to see the following: The robot plans and moves its arm to the joint goal.

By adding link names to the ``touch_links`` array, we are telling the, ## planning scene to ignore collisions between those links and the box. ## Now, we call the planner to compute the plan and execute it. get_attached_objects() and get_known_object_names() lists. MBF can use existing plugins for move_base, and provides an enhanced version of the planner, controller and recovery plugin ROS interfaces. Are you sure you want to create this branch?

We will disable the jump threshold by setting it to 0.0, # ignoring the check for infeasible jumps in joint space, which is sufficient. A tag already exists with the provided branch name. The robot moves its left arm along the desired cartesian path. We are working on a ur10e, and the fisrt task is to make the robot move to a target position. for those of you familiar with gnu-coreutils' mv command, python's shutil.move has one edge case where shutil.move function differs. We create this DisplayTrajectory publisher which is used below to publish You can rate examples to help us improve the quality of examples. ## and a `RobotCommander`_ class.
