+Summary
+-------
+
+Every robot needs to interact with its environment.
+Manipulation capabilities include analysis of the environment around a manipulator, planning the motion of the manipulator to get the end effector where it needs to be, and controlling end effects to do things like pick and place objects.

+Summary
+-------
+
+Motion planning enables your robot to plan movements, including responding to real-world effects such as wheel slip or things in the environment moving.
+This can involve controlling complex chains of actuators and links, such as those found in industrial manipulators.
+ROS motion planning capabilities let you focus on where you want the end effector to be, rather than focusing on controlling every actuator individually.
+
+For mobile robots, ROS also supports navigation capabilities.

+Summary

+
+Perception capabilities are how your robot sees the world.
+They enable your robot to process data from a range of sensors, such as cameras, bump sensors, and LIDAR sensors, and turn that into information the robot can use to plan and control its actions.
+This includes sensor fusion (combining data from multiple sensors into a unified view of the world).
