3D Printed Rover Will Be IoT.

3D printed Mecanum Rover will be IoT.

It is Mechanum Wheel Rover which can be created with 3D printer.

The Mechanum Wheel can move freely to left and right, up and down, diagonal.

We will control Mechanum Rover with WIFI connection.

ESP8266EX is used for control.

Rover link websocket.

(1) The rover to 3D printing.

• TAMIYA gearbox type: http://www.thingiverse.com/thing:1718473

• Yellow DC motor type: http://www.thingiverse.com/thing:1622028

(2) To connect the ESP8266, motor driver and Rover.

• DC motor driver use TOSHIBA TA7291P.
• Please see Step3(1) include("esp_WebSocketServer.ino") for GPIO-PIN used in ESP8266.

(1) Install the environment for ESP8266 on ArduinoIDE.

• caution: esp8266-arduino Ver 2.0.0 over on ArduinoIDE.

https://github.com/esp8266/Arduino

(2) add library.

https://github.com/Links2004/arduinoWebSockets

https://github.com/me-no-dev/ESPAsyncTCP

https://github.com/bblanchon/ArduinoJson

(3) add IDE extention(Arduino ESP8266 filesystem uploader).

https://github.com/esp8266/arduino-esp8266fs-plugin

(1) Download rover controll sketch.

https://github.com/arrowmeiwaracing/mecanumrover

(2) Install rover controll sketch.

• WIFI of SSID, PASSWORD is set in the JSON format file(config.txt) on the ESP8266 file system.

• config.txt upload to ESP8266. Refer to URL for uploading method.
  https://github.com/esp8266/arduino-esp8266fs-plugin

(1) Connect to the ESP8266 web server(port:80) with a browser.

• e.g. http://192.168.1.99/
  index.html will be downloaded from the HTTP server.
  http server port at 80. websocket server port at 81.

(2) You can move four tires separately.

• Client is essential that the touch event pick up. e.g. iPhone, Android phone and tablet.

(1) This sketch contains the OTA function.

• OTA for the code to sketch in order to update the firmware in the OTA via WIFI you have is described.
