A 4WD rover designed for radiation mapping, using a UV sensor as a proof of concept. The system collects and logs environmental data while navigating by using X-Bee.
✔️ Radiation-level simulation using a UV sensor
✔️ Ultrasonic sensors for obstacle detection
✔️ GPS with RTC for real-time location tracking
✔️ SD card storage for data logging
✔️ LDR for automatic head/rear light control
✔️ XBee for wireless control and communication
✔️ Arduino Mega as the main controller
- Microcontroller: Arduino Mega
- Sensors: UV sensor, Ultrasonic, GPS (with RTC), LDR
- Storage: SD card module
- Communication: XBee module
- Chassis: 3-D printed and lasercut
- Programming: C++ (Arduino)
- Data Logging: SD card storage
- Communication Protocol: XBee wireless @ 9600 baud rate
- Navigation: GPS-based tracking
- Simulation: Proteus
- The rover controlled using laptop or else with handheld 4 button pcb joystick by using X-Bee.
- The GPS logs the rover’s position with a date and timestamp.
- The ultrasonic sensors detect obstacles to avoid collisions.
- Data (UV levels, location, time, etc) is stored on an SD card.
- The LDR automatically turns the light on/off based on ambient brightness.
- Wireless transmission via XBee allows real-time monitoring.
