            <li> If you could add another sensor to the robot what would that be?</li>
            <li>
                Why do you think we need the said sensor and where would it be used?
                <ul>
                    <li>For example, we added lidar sensors to have a functional navigational system. The lidar sensors provide 360 distnace sensor, providing a local 2D mapping for the robot.</li>
                    <li>For lidar sensor, we would add a Topic that would recieve the node connected to the output of the sensor and Publishes values to the Topic. We may use this information by Subscribing to the said Topic.</li>
