This line follower robot is very small and simple. This robot is running fast and follow the line very smoothly. You may see the video here.
Mechanics
All mechanical and electrical parts are mounted on a proto board, and it also constitutes the chasis.
Built based on PIC microcontroller, this robot has multi functions, you might use this robot for several objectives.
The robot’s objectives are the following:
1. Follow a line with sharp turns
2. Maneuver through breaks in the line
3. Detect obstacles and manuever around them
4. Identify colors to be able to locate green and aluminum victims.

Micro robots built by researchers for medical purpose. Here the complete news:
Artificial bacterial flagella are about half as long as the thickness of a human hair. They can swim at a speed of up to one body length per second. This means that they already resemble their natural role models very closely.
They look like spirals with tiny heads, and screw through the liquid like miniature corkscrews. When moving, they resemble rather ungainly bacteria with long whip-like tails. They can only be observed under a microscope because, at a total length of 25 to 60 µm, they are almost as small as natural flagellated bacteria. Most are between 5 and 15 µm long, a few are more than 20 µm.
Mimicking nature
The tiny spiral-shaped, nature-mimicking lookalikes of E. coli and similar bacteria. are called “Artificial Bacterial Flagella” (ABFs), the “flagella” referring to their whip-like tails. They were invented, manufactured and enabled to swim in a controllable way by researchers in the group led by Bradley Nelson, Professor at the Institute of Robotics and Intelligent Systems at ETH Zurich. In contrast to their natural role model, some of which cause diseases, the ABFs are intended to help cure diseases in the future.

French robotics specialist Robosoft and SRI International have demonstrated a new service robot designed to assist the elderly at home.
The RobuLAB, is able to navigate, follow and assist people moving from room to room using SRI Karto navigation software.
This book will teach you many things about AVR microcontroller. As we know, AVR family is cheap, easy and the most used microcontroller in Robotics.
By the time you complete the text and projects you will:
• Have an intermediate understanding of the C programming language.
• Have a elementary understanding microcontroller architecture.
• Be able to use the WinAVR and AVR Studio tools to build programs.
• Be able to use C to develop microcontroller functions such as:

Introduction
PDA Robotics - Using Your Personal Digital Assistant to Control Your Robot will give you the expertise to create anything. One of many areas that I will touch on is the smart distributed network, where each robot can pass the information that it gains onto the “collective” to be shared with other robots. For instance, if two PDA Robots pass each other they can exchange information about a room in the house that has been mapped, saving any duplication of effort. The robots can synchronize to coordinate effort as well. A good example of a coordinated autonomous effort is the idea of traffic being directed by a computer system.
Sound activation or tone detector usually used for robot start activation. When a sound received by microphone in tone detector, the robot will start to move.
I’ve collected some schematic diagrams of sound activation as follow:
Sound Activation schematic 1
Sound Activation schematic 2
This interesting information come from ScienceDaily, said about the future of robotics which could be made by anyone, not just industries or company who able to make a “big” robots.
====================
Alexander Stoytchev and his three graduate students recently presented one of their robot’s long and shiny arms to a visitor.
Here, they said, swing it around. And so the visitor tentatively gave the robot’s left arm a few twists and twirls. The metal arm was heavy, but still moved easily at its shoulder, elbow and wrist joints.
Then the graduate students hit some keyboard commands and the robot replayed those exact arm movements.
It was all incredibly quick, smooth and precise.
This book will show you how to make remote-controlled robot, step by step…
Preface:
In recent years robots have captured the interest of more and more people. Thanks to movies and TV, the notion of the robot as a mechanical companion and servant has become a common concept. As interest in robots grew, a number of books showing how to build robots at home began to appear. These books, however, were very technical, showing how to build computer-controlled mobile platforms that are considered by most to be true robots.
Introduction:
This book is about the Atmel’s AVR RISC microcontroller series. It covers architecture, design, and usage of this controller in various sample applications. Atmel Corporation (www.atmel.com) is a leading manufacturer of integrated circuits (ICs). AVR is the name of a microcontroller series that Atmel produces and that is the subject of this book. RISC (Reduced Instruction Set Computer) is a popular architecture for modern processors (more about RISC in a later chapter).
Before we get into the details, let us see why it is important to learn about microcontrollers in general and the AVR RISC series in particular. A recent white paper by Sun Microsystems, on picoJava Microprocessor core architecture claims that an average home, by the end of the decade, will contain between 50 to 100 microcontrollers controlling digital phones, microwave ovens, VCRs, televisions sets and television remotes, dishwashers, home security systems, PDAs, etc. Even though this may only reflect the position of a typical home in the advanced countries, there is no denying that even this reflects a huge volume of the microcontroller and microprocessor usage in the home environment. Besides home use, another area that is fueling the microcontroller growth is electronic commerce.
