Soil testing is an important process in agriculture, environmental monitoring, and civil engineering. However, traditional soil testing methods are time- consuming and labor- intensive. In this paper, we propose a Bluetooth-controlled soil testing robot that can automate the soil testing process. The robot is equipped with a soil sensor and a Bluetooth module, which allows it to communicate with a smart phone app. The app can control the movement of the robot and receive real-time data from the sensor. We also present the design and implementation of the robot, including the hardware and software components. Finally, we evaluate the performance of the robot in different soil types and compare it with traditional soil testing methods.
