move_arm_warehouse Documentation

move_arm_warehouse: A general arm planning and control interface

The move_arm package provides an implementation of a action (see the actionlib package) that, given a goal in the world, will attempt to reach it with a robot arm. The move_arm node links together a planner, trajectory monitor and trajectory controller to acheive its goal. It supports any planner that provides a GetMotionPlan interface and any controller that provides services for setting, querying and canceling trajectories. The node is designed to be modular and so uses ROS services for planning, control and IK and does minimal computation within the node itself.

Also, see the documentation for the planning_environment package.

List of nodes:


All these nodes take standard ROS arguments. The interface to the node is through ROS parameters, services and topic. A more detailed description of the interface can be found in the move_arm package documentation.

running

In order to run, 'move_arm' needs a robot description (together with its planning and collision description) to be loaded. In addition to this, the 'planning_environment' should be receiving both state and map information constantly, so that the environment is considered known. A node that can perform motion planning needs to be running and a controller for the arm need to be running as well. Running a node that can perform inverse kinematics is optional.

Example launch files that start all the necessary components for navigation for the PR2 robot can be found in the pr2_arm_navigation and pr2_3dnav packages.
