Build Electronic Circuits Like a Pro

If you want to build electronic circuits, you need to connect the components of your circuit somehow. If you expect to make your circuit work more than just a few times, you need a solid way of connecting them. You need to create a printed circuit board (PCB).

"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."

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.

An Android Brain for your Bot

The Objective - When your Bot has outgrown your Arduino, it wants to talk, an urge to communicate and Network(Social). A larger brain over the smaller control system is the need. Then a Networked Drove of Bots ! is possible.

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.

An Android Brain for your Bot

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.

AI Dodo with a Wikipedia Brain

Wikipedia Search Results combined with an AI Query and Data-mining Engine integrated with a High Quality Text-to-Speech; can help people hear Answers to Questions they ask. Optional pictures and video on a concealed LCD Screen, Packed into a Feather Bag called "Dolly the Know-all Dodo". A witty, impertinent, extra-smart Bird-Bot. (2009 - Ideas of delabs)

AI Dodo with a Wikipedia Brain

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. "

These are some sites that help you read out wikipedia.

Make an Encoder for your Bot

I want to build a cheap wheel encoder by myself. - Need some help here. I want to build a cheap wheel encoder by myself. Now, my idea was to use a photodiode and a LED. What i don't know is how to use the output from photodiode to put on a GPIO on my MCU board. Do i need some resistors or something. Aaaa, i need a high level of 5V for my GPIO. I - AV

Answer

Please study Links Below
 
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

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). .....

Incremental Optical Encoders

Ananth -

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 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

"For measuring distances I chose to use SRF08. It is an ultrasonic ranger with I2C bus and measure range from 3 cm to 6 m. The sensor has a beam width of 55 degrees (-6 dB points) and when mounted on top of one of the servos it can be used for covering well over 180 degrees."

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.

Vicacopter – Open Flight Robotics

Source code and many notes used in Vicacopter, the 1st English language source code for a fully functional helicopter autopilot.

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.

Vicacopter - Open Flight Robotics

Some Features
  • 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

These valuable learning materials are partly derived from Robot Builder's Guide of Fred Martin, the course notes at the Massachusetts Institute of Technology.

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.

Wide Skill Spectrum by Building a Robot

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"

delabs Notes

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.

BEAM Robotics - Simple Nature Inspired Bots

BEAM is an acronym standing for Biology, Electronics, Aesthetics, Mechanics. While BEAM robots are often simple (consisting of a solar cell , motor, 2 transistors , and capacitor ), robots as complicated as 8-jointed, 4-legged walking spiders have been built using the principles of BEAM.

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.

BEAM Robotics

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.
