Robotics Book: Amphibionics - Build Your Own Biologically Inspired RobotIntroduction:
The robots in this book were designed to imitate biological lifeforms. Watching the snake robot moving through a room, it is interesting to observe the surprised reactions of people when it quickly turns towards them. People actually regard the robot as being alive. I am struck with the thought that although these machines are not alive in our biological sense, they actually are alive, but as life-forms unto themselves. These artificially intelligent machines are the products of  uman imagination and technical understanding. As the technology advances, the line between living and non-living matter is slowly becoming blurred.

High Current H-Bridge with MOSFET

February 10th, 2009 by Robot Technology | 1 Comment | Filed in Electronics

High Current H-Bridge with MOSFET circuit diagram>

One important feature of MOSFET transistors is that they contain an intrinsic (unavoidable, built-in) diode between their drain and source. This diode acts as a catch diode in an H-bridge configuration, and most MOSFET datasheets specify the parameters of this diode. It is thus possible to use this built-in diode of the transistors and not provide external ones if the specification of this diode meet the design requirements. For bipolar transistors there’s no such intrinsic diode so external diodes always have to be provided.

For more explanation, check up this explanation

And here the sample h-bridge schematic diagram with MOSFET:

Rapid Learning In Robotics

January 17th, 2009 by Robot Technology | 2 Comments | Filed in Robotics Ebooks, Robotics Tutorial

rapid learning in robotics Introduction
In school we learned many things: e.g. vocabulary, grammar, geography, solving mathematical equations, and coordinating movements in sports. These are very different things which involve declarative knowledge as well as procedural knowledge or skills in principally all fields. We are used to subsume these various processes of obtaining this knowledge and skills under the single word “learning”. And, we learned that learning is important. Why is it important to a living organism?

Learning is a crucial capability if the effective environment cannot be foreseen in all relevant details, either due to complexity, or due to the nonstationarity of the environment. The mechanisms of learning allow nature to create and re-produce organisms or systems which can evolve — with respect to the later given environment —optimized behavior.

Microcontroller Ebook: C Programming for Microcontrollers

December 24th, 2008 by Robot Technology | 10 Comments | Filed in Microcontroller, Programming

c programmingC Programming for Microcontrollers – Featuring ATMEL’s AVR Butterfly and the free WinAVR Compiler

Introduction

C Programming and microcontrollers are two big topics, practically continental in size, and like continents, are easy to get lost in. Combining the two is a little like traipsing from Alaska to Tierra del Fuego. Chances are you’ll get totally lost and if the natives don’t eat you, your infected blisters will make you want to sit and pout. I’ve been down this road so much that I probably have my own personal rut etched in the metaphorical soil, and I can point to all the sharp rocks I’ve stepped on, all the branches that have whacked me in the face, and the bushes from which the predators leapt. If you get the image of a raggedy bum stumbling through the jungle, you’ve got me right. Consider this book a combination roadmap, guidebook, and emergency first aid kit for your journey into this fascinating, but sometimes dangerous world.

I highly recommend that you get the book, ‘The C Programming Language – second edition’ by Kernighan and Ritchie, here after referred to as K&R. Dennis Ritchie, Figure 1, wrote C, and his book is the definitive source on all things C.
