ev3dev-web-server

This simple web server for ev3dev enables the user to:

• Monitor sensor values and motor positions
• Control motors by sending commands
• Change sensor modes
• Steer the robot using a joystick-like interface

This project consists of two components:

1. The actual web server, a Python script which sends values to clients and receives commands through WebSockets.
2. A website which receives values through JavaScript and sends values to the server.

Getting Started

1. Copy this repository to your ev3dev device, e.g. by cloning.
2. Install tornado:
   $ sudo apt install python3-tornado
3. Run python3 server.py.
4. In a browser, open <ev3dev ip>:8000.

Password Protection

Access to the website can optionally be protected by a username and password, using HTTP Basic Authentication.
To enable password protection, follow these steps:

1. Install htpasswd, which is included in apache2-utils:
   $ sudo apt install apache2-utils
2. cd into the ev3dev-web-server directory, then create a .htpasswd file (replace <username> by a username of your choice):
   $ htpasswd -c .htpasswd <username>
3. Users are now asked to authenticate before they can access the website.

Note that you should change the password of the robot user. Otherwise, anyone can log in via ssh using the default password (maker) and delete or change the .htpasswd file.
The password can be changed via sudo ev3dev-config.
