1. Service robot communication systems and system self-configuration (https://patents.google.com/patent/US10040201B2/en)
Abstract A service robot is provided to communicate with other devices of a service location, such as another robot. A first and second robot may be tasked with performing a customer service task requiring a physical interaction. The first robot may determine that the second robot lacks instructions to perform the customer service task. Upon making the determination, the first robot retrieves physical interaction instructions and causes the second robot to load and execute the physical interaction instructions. The second robot is then transformed, by the first robot, into a configured robot able to perform the customer service task.ros

gazebo_ros_pkgs is a set of ROS packages that provide the necessary interfaces to simulate a robot in the Gazebo 3D rigid body simulator for robots. It integrates with ROS using ROS messages, services and dynamic reconfigure.
Some of the features of gazebo_ros_pkgs include:
-
- Leverage existing standard ROS plugins for Gazebo
- Improves out of the box support for controllers using ros_control
-
Many simulated sensors available and ready to work

(1) ROS overview (http://gazebosim.org/tutorials?tut=ros_overview&cat=connect_ros)
To achieve ROS integration with stand-alone Gazebo, a set of ROS packages named gazebo_ros_pkgs provides wrappers around the stand-alone Gazebo. They provide the necessary interfaces to simulate a robot in Gazebo using ROS messages, services and dynamic reconfigure Some features of gazebo_ros_pkgs:
- Supports a stand alone system dependency of Gazebo, that has no ROS bindings on its own
- Builds with catkin
- Treats URDF and SDF as equally as possible
- Reduces code duplication with Gazebo
- Improves out of the box support for controllers using
ros_control - Integrates real time controller efficiency improvements from the DARPA Robotics Challenge
- Cleans up old code from previous versions of ROS and Gazebo
