Hi, today I prepared the final article about Arduino + Raspberry Pi robot Pluto. We are going to connect camera and add video streaming feature to our browser control panel.

If you ever asked yourself how to pilot a robot via browser, then you may want to connect it to a Raspberry Pi 3 with WiFi module, develop python based web server and have fun!!!
