Here is a demo video:
This project was build based on idea on how to make a simple and cheap online surveillance camera robot that everyone can build. Not only that the robot also have to be easy to use and maintain. Using the raspberry pi, few cheap components, a robot chassis/RC car, and webiopi tutorial on the MagPi magazine this project was successfully build. For launching this robot to be accessible online, ngrok service from www.ngrok.com is used. Without any hectic and difficult port forwarding configuration this robot now can be controlled from anyone in the world by just using firefox or chrome browser.
No soldering is required to build this robot because I use jumper wire to connect all necessary connection between the GPIO to the L298n motor driver module, and then i connect the two dc motor to the mounting hole on the L298n module.
