Giant UGV Robot controlled via smartphone

Coyote-UGV

Giant UGV Robot controlled via smartphone

More or less a port of Hydra ROV

Notes

• This project is work for Gunners Team (Faculty of Engineering, Suez Canal University).
• This project was made for International UGV competition.

Project Structure

This project consists of 3 stages :-

• Android controller.
• PC Bridge.
• PIC Microcontroller app. (Arduino app as backup)

Work Flow :

• Via any android phone you can control the robot via usb cable to PC or wifi/bluetooth network.

• PC bridge handles the orders then send them to the PIC MCU (Arduino) via Ethernet using UDP / Serial Port.

• In the PIC (Arduino) it recieves the order and behaves according to it.

• PIC (Arduino) can send signals from sensors to PC Bridge via UDP / Serial Port.

Project Building Blocks :

• Android App :

    - A simple user interface consists of buttons for control and seekbar for speed
    - When interacting with UI the app writes to logcat stream
    - Written in Android Java
  

• PC Bridge :

    - UI changes according to user input or robot's output
    - Contains places to show user or robot's action
    - Connects with android via ADB and reads logcat stream
    - Sends data to robot via Ethernet cable using UDP (or Serial Port in case of Arduino)
    - Written in Java 
  

• PIC Microcontroller App :

    - Recieves data from PC via ENC28J60 Chip
    - Processes Data and send signals to motors/sensors
    - Sends running values motors
    - Data Transmission is via UDP
    - Written in MikroC (MikroElectronica Embdedded C compiler)
  

• Arduino Board App :

    - Backup to PIC Microcontroller
    - Simple sketch to recieve data on serial port and process data 
    - Envoking actions according to sent data
