Hobby DIY Electronics - Do it Yourself, The World Over.
Use the Arduino for emulating the role of the Spine and an Android System for the Big Networked brain. You can hack an Economy Android Phone to make your Robot an Einstein.
Now for Simulating the Soul, which even the most Advanced Robotic Scientist is unaware of; All you need is Cloud.
How to do that
We have to try create some Robots which are Non-Motor based, Soundless, No Rotary action. Minimum Metal Used, Silicone and Epoxy based parts. They will have 3G and Wi-Fi integrated and the Soul, the Intellect and the Instincts can be upgraded In-system online. The Cloud will be God.
Why the need
The Robot in Literature - Coppélia
Coppélia concerns an inventor, Dr Coppelius, who has made a life-size dancing doll. It is so lifelike that Franz, a village swain, becomes infatuated with it and sets aside his true heart's desire, Swanhilde.
She shows him his folly by dressing as the doll, pretending to make it come to life and ultimately saving him from an untimely end at the hands of the inventor.
The Truth - Swanhilde and her friends find themselves in a large room filled with people. However, the occupants aren't moving. The girls discover that, rather than people, these are life-size mechanical dolls. They quickly wind them up and watch them move. Swanhilde also finds Coppélia behind a curtain and discovers that she, too, is a doll.
The sad part of this Opera and The Nutcracker is that Inventors of Bots are shown as Evil Scientists. We have to clear the stigma by making a Giant King Kong Bot.
First written 2008 in other areas, enhanced post till 2012 - An idea by "Bot with a Soul" - delabs
Idea from Polly -
Make a AI Robot in the form of a Cartoon Parakeet. Something like polly the techno parrot below. When you ask a question or a unique term like "Solar Energy" or "Vitamin C" it can use its AI - Artificial Intelligence to read out a Wikipedia Page and if not Satisfied browse the web internally and suggest alternative pages to read out. It can have a Dockable Tablet Interface too for Visualizing its AI and Articles.
Who made Polly Shown on the right in CrossSection - Rob and Roberta Radtek
"Direct from the Institute of Robotic Technology comes this amazing interactive robot pet-- POLLY THE TEKNO PARROT! Polly talks with people he senses around him just like a real parrot. Polly's electronic cuircuits can detect motion, sound, light and even touch. He will snore off to sleep at night and wake up in the morning. If you pet him, he will "coo" and move his wings. "

Optical Encoder Project - "Many years ago, I competed in MASLab, an MIT competition to build an autonomous robot. A year or two after that, I was on the MASLab staff, helping prepare the hardware for the year's competition. One of the projects I worked on was an optical encoder."
About Encoders and How to Make an Encoder Wheel
"A typical encoder uses optical sensor(s), a moving mechanical component, and a special reflector to provide a series of electrical pulses to your microcontroller. These pulses can be used as part of a PID feedback control system to determine translation distance, rotational velocity, and/or angle of a moving robot or robot part."
Make your own rotary encoder
"In the first and second post of this series you saw the basics of how to use photointerrupters. Now it’s time for practice. We make a rotary encoder. Here we take a single photointerrupter that gives us the pulses we can count."
Make Your Own Encoders chat - "I'm starting a·dedicated·thread on the specific encoders I used on my Homebuilt platform. I had great results. A word about the encoder disks: they must be mounted PERFECTLY to achieve consistency. Perfectly flat, true, and concentric.
Incremental Optical Encoders
Here is a method for making an encoder with two sensors for your application. If you only need speed sensing, you may want to skip down to the construction section. The important variables are the radius of the circle (r), the distance between the two optical sensors (s), and the number of divisions in the wheel (d). .....
Use a photointerrupters, even from an old wheel mouse if you want or build one. Then you need a Wheel with stripes and a Schmitt Trigger Gate or Comparator

"I started playing with electronics as a hobby when I was 14. Since then I have finished a Master's degree and founded two electronic design companies."
Build Electronic Circuits Like a Pro
The radar sensor uses a Ultra-Wideband (UWB) chip from Novelda. It sends out electromagnetic pulses and analyzes the pulses that are reflected back. In the video above, a part of the electromagnetic pulse will be reflected back when it hits the wall and a part of it penetrates the wall and is reflected from the cabinet behind the wall.

Dave's Sumo Robot project
"I was fortunate enough to find a professor who was willing to supervise my project Dr.Ferhat Khendek. I have decided to do the documentation in HTML format and make it public to anyone who is interested in robotics."
There are two class of robots, remote controlled and autonomous. Remote controlled are operated by a human participant via RF link. Autonomous on the other hand has to be self contained with no human influence in its operations with the exception to its programming.

BeagleBot - Beagle powered robot - A small experimental robot with Beagle Board as it's heart.
Servo System -Double Hitec HS-422 servos mounted on a special two axis brackets. - 5 pcs of normal RC servos with 50 Hz PWM control. ATMega16 at the expansion board creates the PWM for all of the servos and provides an I2C control interface for them. User space application running on beagle board can thus control the servos just sending only a simple I2C message.
"The Beagle Board is a low-cost, fan-less single-board computer based on Texas Instruments OMAP35x processors featuring the ARM Cortex-A8 core"
The USB-powered Beagle Board is a low-cost, fan-less single board computer that unleashes laptop-like performance and expandability without the bulk, expense, or noise of typical desktop machines.

Hobby robotics and programming of the Atmel AVR series of micro controllers. Larry Barello is a designer of embedded processors for industrial, medical and communications industries.
Small real time operating system RTOS called AvrX, short for AVR Executive. he latest is tuned to work with the GNU and IAR C compilers.
Spring 2000, I decided to rebuild Dilbert on a printed circuit board using the Atmel AT90S8535 processor. This processor is very much like the 8515 in Dilbert with three significant exceptions: it contains an on-board 8 channel 10 bit A/D, it doesn't have memory expansion capability and there is a separate RTC timer/clock circuit.

Dallas Personal Robotics Group - DPRG
DPRG members have created some tips and howto for the common issues faced by robot builders.
After 7 years in the Garland warehouse, the DPRG is searching for a new home. The new plan is to try the hackerspace model, combining grants, donations, and membership fees to fund a fully equipped community workshop.
Ron of DPRG is using the "Rarey Technique" for Taming a Wild Robot that went Berserk. ;-)
Establishing a Dallas Maker Space
Every robot needs sensors of some type to interact with the world around it. Infrared LEDs and Infrared photo detectors are one way to detect objects, but they are easily foiled by surrounding ambient light.
IR Proximity Detector by Jeff Koenig, August 1998
"Proximity sensors are commonly used on mobile robots for obstacle avoidance. This article presents a simple PIC-based, modulated infrared proximity sensor with dual angled transmitters and single receiver."

Vicacopter - Open Flight Robotics
Vicacopter uses a ground computer for flight control. An 8 bit airborne microcontroller handles rate damping, PWM, & sensor capturing. The ground computer handles navigation & provides a simple instrument panel. This was the cheapest & most flexible way to fly. The system can be converted to a completely airborne autopilot very simply.
- Automated landing & takeoff
- Sonar position sensing for indoor flight
- GPS position sensing for outdoor flight
- Ground station instrument panel
- Untethered communication from pilot to ground station
- Curved or linear paths
The Tri-Roter one used 3 gyros for short term rotation sensing, 2 accelerometers for long term tilt sensing, 3 magnetometers for long term heading sensing, a high quality GPS module for horizontal position, a barometer for altitude sensing. A 3rd accelerometer was too sensitive to vibration & altitude changes to be any good. Because of the long term sensors & the very stable gyros, the orientation was always pretty accurate & didn't drift.

Wide Skill Spectrum by Building a Robot
Basic Mechanics— Describes basic mechanics, friction, and the simple machines that comprise the building blocks of more complex machines, like robots.
Sensor Design - Without sensors, a robot is just a machine. Robots need sensors to deduce what is happening in their world and to be able to react to changing situations. This chapter introduces a variety of robotic sensors and explains their electrical use and practical application.
Robot Control - The most common kind of robot failure is not mechanical or electronic failure but rather failure of the software that controls the robot. For example, if a robot were to run into a wall, and its front touch sensor did not trigger, the robot would become stuck (unless the robot is a tank), trying to drive through the wall. This robot is not physically stuck, but it is "mentally stuck"
When you build a robot, you are dealing with Mechanical, Electrical, Electronic and Computer Technologies with the Interfacing.
The improvement in the Wireless Communication, Low Power Hi-Speed Semiconductors coupled with compact gigabytes of Flash/HDD may help build a Creative Robot with a smart brain.

Solarbotics.net - BEAM Reference Library
The BEAMAnt is a phototactic bot which has potentially complex behavior depending on the light level. It has two photodiodes for light sensing, and two antennae which switch the motors into reverse when they touch something.
Mechanisms and principles
The basic BEAM principles focus on a stimulus-response based ability within a machine. The underlying mechanism was invented by Mark W. Tilden where the circuit (or a Nv net of Nv neurons) is used to simulate biological neuron behaviours. Some similar research was previously done by Ed Rietman in 'Experiments In Artificial Neural Networks'. Tilden's circuit is often compared to a shift register, but with several important features making it a useful circuit in a mobile robot.
