+## Purpose of the Area in the Service Robot
+
+The purpose of the area in the service robot is to provide a functional and efficient environment for performing various manipulation tasks. The area is designed to accommodate the robot's hardware components, including the mobile base, arm, and sensors, and to facilitate the execution of tasks such as picking, placing, and manipulating objects. The area is also equipped with the necessary software modules and tools to enable seamless integration and coordination of the robot's components, ensuring reliable and accurate performance.
