The RViz plugin provides a very interesting mechanism to interact with MoveIt! but it could be considered quite limited or even cumbersome due to the lack of automation. In order to fully make use of the capabilities included in MoveIt!, several APIs have been developed, which allow us to perform a range of operations over it, such as motion planning, accessing the model of our robot, and modifying the planning scene.
In the following section, we will cover a few examples on how to perform different sorts of simple motion planning. We will start by planning a single goal, continue with planning a random target, proceed with planning a predefined group state, and finally, explain how to improve the interaction of our snippets with RViz.
In order to simplify the explanations, a set of launch files have been provided to launch everything required. The most important one takes care of launching Gazebo, MoveIt!, and the arm controllers:
$ roslaunch rosbook_arm_gazebo rosbook_arm_empty_world...
