The Technical Design Blueprint 1. The Hull (The Raft) To ensure stability while carrying a water tank and battery, a catamaran (twin-hull) design is best. Pontoons: Two parallel 1-meter lengths of 40 mm PVC pipe. Aero-Dynamics: 40 mm PVC cones (reducers or 3D-printed caps) on all four ends to reduce water resistance. Structure: Connect the two pontoons using 40 mm T-pieces and cross-bars to create a "ladder" frame. This platform will hold your electronics box and the sample tank. 2. Propulsion & Steering Motor: A waterproof brushless motor with a 3-blade propeller. Steering: You can use a differential thrust setup (two motors, one on each hull) which eliminates the need for a physical rudder, making it more maneuverable in weedy river water. 3. The Sampling System (The Payload) Intake: A weighted 12V submersible pump or a peristaltic pump (better for maintaining sample integrity). Storage: A small HDPE tank (approx. 500ml–1L) mounted in the center of the raft. Sensors: In-situ probes for pH, TDS (Total Dissolved Solids), and Dissolved Oxygen (DO). These provide real-time data before the physical sample is even taken. 🛰️ Navigation & Control (Drone Integration) By using a Flight Controller (e.g., Pixhawk or Ardupilot), your raft gains "Rover" capabilities: GPS Tagging: Every time the pump activates, the GPS logs the exact coordinates ( ). Contamination Mapping: By measuring TDS/pH at different distances from a discharge point, you can calculate the Pollution Gradient. Telemetry: Real-time data is sent back to your ground station (laptop/tablet). 🧪 Data Workflow & Lab Integration Stage Action Output Field GPS + Sensor Log Digital CSV file with pH/TDS/Location Lab Chemical/Microbial Analysis Detailed Lab Report Final Data Merging A heat map showing contamination levels vs. distance Note on "Mother Printer": To automate the printout, you can set up a Cloud-connected API (like Google Sheets or a custom Python script). Once the lab results are typed in, the system matches them to the GPS coordinates and automatically sends a formatted report to your office printer. Suggested Components for your Shopping List: Controller: FlySky FS-i6 (Remote) + Pixhawk 4 (Brain). Power: 3S or 4S LiPo Battery (12V compatible). Pump: 12V DC Diaphragm Pump (Self-priming). Sensors: Gravity Analog pH & TDS sensor kits for Arduino/Raspberry Pi. Would you like me to draft a wiring diagram or a Python script that helps map the GPS coordinates to the contamination levels? AI can make mistakes, so double-check responses Would you like me to draft a wiring diagram or a Python script that helps map the GPS coordinates to the contamination levels?Yes This blueprint provides the wiring logic for your PVC raft and a Python script to automate your contamination mapping. 🔌 1. Wiring & Control Logic To integrate a 12V pump with a drone flight controller (like a Pixhawk), you must use a Relay or an Electronic Speed Controller (ESC) to prevent damaging the low-voltage electronics. Arduino Forum Arduino Forum +1 Main Power: Connect your 3S/4S LiPo Battery to a Power Module which regulated 5V to the Pixhawk while passing the full battery voltage to the motors and pump. The Pump: Connect the 12V Pump's positive wire to a 5V Relay Module. Connect the Relay’s signal pin to a PWM output port on the Pixhawk (e.g., AUX 1). Navigation: Plug your GPS/Compass module into the dedicated GPS port. Sensors: Connect your pH/TDS probes to an Arduino or a companion computer (like a Raspberry Pi) to log data alongside the GPS coordinates. Arduino Forum Arduino Forum +6 🐍 2. Python Mapping Script This script uses the Folium library to create an interactive map that visualizes contamination levels based on distance from a source. GeoPandas GeoPandas +2 python import folium from folium.plugins import HeatMap import pandas as pd # 1. Sample Data (GPS + Contamination Reading) # In practice, this will be your CSV file exported from the raft data = { 'lat': [-17.824, -17.825, -17.826, -17.827], 'lon': [31.050, 31.051, 31.052, 31.053], 'tds_level': [150, 450, 800, 1200] # Example contamination metric } df = pd.DataFrame(data)
