This is a very interesting robotic tutorial. You will learn how to build a spy robot (spybot) featured with WiFi connection. This robot needs a network camera and a WiFi router to work as a spy. You need little knowledge of computer networking, especially about Router and IP address configuration.

Do you know Orocos..? Orocos is a C++ framework for component-based robot control software, of course this is an open source software.
Orocos is the acronym of the Open Robot Control Software project. The project’s aim is to develop a general-purpose, free software, and modular framework for robot and machine control. The Orocos project supports 4 C++ libraries: the Real-Time Toolkit, the Kinematics and Dynamics Library, the Bayesian Filtering Library and the Orocos Component Library.

H-Bridge is an electronic circuit which will control the mechanical of the robot.
The H-Bridge is the link between digital circuitry and mechanical action. The computer sends out binary commands, and high powered actuators do stuff. Most often H-bridges are used to control rotational direction of DC motors. And unless you buy a potentially expensive motor-driver, you need an H-bridge to control any robot with a motor.
This is a quickly sketched H-Bridge circuit with supporting circuitry.
First lets talk about what a transistor is. These nifty chips revolutionized the electronics industry and you would be hardpressed to find something electronic that does not have at least a few thousand of these in them. So what do they do? They can control a flow of electrons by applying a voltage to them. The plumbing equivalent would be a water valve. By rotating the valve, a very large flow of water can easily be controlled.
