one of which is used for controlling the lawn grass cutter and another is for its mobility. These controllers are powered by the same battery, and therefore, battery wastage depends on their usages. The subsystem, "Lawn Grass Length/Not Lawn Grass Estimator" is newly developed.

The robo-mower is used for experiments by attaching sensors, a single-board computer, a personal computer and peripheral devices on the robo-mower, as shown in **Figure 3**. All these devices are managed by an ROS (robot operating system) running on the personal computer. The robo-mower can be autonomously driven; however, it is controlled using a Bluetooth controlling device in the experiments to increase the accuracy of the experiments. A camera can be used as a sensor, but it is inadequate for the experiments due to its high cost of image processing software and hardware. In the experiments, it will be shown that no camera is needed for the required estimation.
