Mosquitos may lay eggs in shallow bodies of water near shore. Water samples may need to be collected for analysis, and manual collection of the water samples can be potentially a hazard to the personnel. For this reason, an amphibious water sampling rover was created by a capstone project team. This capstone project team was formed with five undergraduate engineering technology students. This project was started in the Spring semester of 2022 and concluded in the Fall semester of 2022. This project generated a rover, and the rover can navigate both on land and on water. And it can perform the water sample collection task. The rover can be controlled over a remote PC, and it can collect water temperature data, and the data can be sent remotely over the internet. For wireless communication, a sub-GHz LoRa module is used. The rover can also communicate over WiFi. A GUI (Graphical user interface) program was developed to collect data from the rover and to control the rover remotely. The GUI program obtains the GPS location of the rover and displays the location of the rover on a map. For the control of the rover, ROS (Robot Operating System) was utilized. A Raspberry Pi 3B+ board is used as an intelligence unit of the system. The collected samples can be brought to a laboratory for further analysis. In this paper, the details of the amphibious sampling rover and the educational lessons via this capstone project are presented.
