In the first week, we attended the IETP orientation, met our advisor, and submitted a project title. We discussed our first idea with the advisor, received feedback, and then brainstormed as a team. Finally, we prepared and submitted three improved project titles.

In week two, our  initial ideas has a lack of uniqueness. We brainstormed again, and a team member proposed an Automated Underground Water Detector. The team agreed it was a strong idea, and we finalized and submitted it through the project form.

In Week 3, we focused on building the project foundation. We researched underground water detection using the Wenner method and studied robotic sensing systems. We identified the main subsystems, assigned team roles, and started writing the project proposal. We also discussed the design to keep it within budget.

In Week 4, we finalized the project proposal and improved the technical design. We prepared system diagrams, studied key components, and discussed how they work together. We met our advisor for feedback.

Focused on mechanical design using SOLIDWORK, including chassis modelling, wheel and motor mounting design, torque consideration, and ensuring stable movement of the Automated Underground Water Detection Robot Car on different soil surfaces.

Purchased a ready-made robot car chassis and modified it as needed, mounted motors and wheels, and adjusted the structure to fit the sensing, control, and power components.

Integrated the mechanical structure with the Arduino-based control system by securely mounting the Arduino, battery, sensors, and wiring on the robot car chassis, and tested movement stability and component placement.

Tested the Automated Underground Water Detection Robot Car on dry, wet, and moderately moist soil to evaluate underground water detection accuracy and overall system performance, and made final adjustments based on the results.

Presented the Automated Underground Water Detection Robot Car prototype to our advisor for evaluation, demonstrated its underground water detection capability, and submitted the final project documentation.
