  1. Beginners Robotics Guide : Image Processing -I

    THEORY OF IMAGE PROCESSING (Special Thanks to Pulkit Gaur)

    Modern digital technology has made it possible to manipulate multi-dimensional signals with systems that range from simple digital circuits to advanced parallel computers. The goal of this manipulation can be divided into three categories:

    * Image Processing image in -> image out

    * Image Analysis image in -> measurements out

    * Image Understanding image in -> high-level ...
  2. Arduino/Riduino Motor Shield - Single Sided DIY

    I wanted a single sided motor shield which would allow me to control a few servos and 2 DC Motors. All this while allowing easy sensor interfacing. The shield had to be single sided and DIP for DIY.

    The shield given below is the result for the same.

  3. Beginners Robotics Guide : OP-Amps in Robotics

    In this article we will have a look at Operational Amplifiers ( OP AMPS ) which are heavily used in robotics and interfacing sensors . The article is meant for people with no knowledge of Op-Amps to those who know some things about them . It starts of explaining the basics then moves to type of operations which an op-amp can perform lastly gives a few examples of where these are used in a simple robot ( line follower , fire fighting , sonar based , BEAM ).

    What is an Op Amp
  4. Beginners Robotics Guide : Mobile Robot Navigation

    "Mobile Robot Navigation" covers a large spectrum of different systems. requirements and solutions. The aim of this article is to study this range of requirements, identify the major areas within the scale which are most commonly used, and to discuss appropriate systems for meeting these requirements.

    The key difference between robotic and human navigation is the quantum difference in perceptual capabilities. Humans can detect, classify, and identify environmental features ...
  5. Beginners Robotics Guide : Basic Electronics - II

    This second tutorial introduces you to the basic circuit components like resistors , inductors , capacitors and how they work . Also what are the various laws involved and how to use them .


    We need some way to control the flow of current from a voltage source, like a battery, so we do not melt wires and blow up batteries. If you think of current, charge flow, in terms of water flow, a good electrical conductor is like big water pipe. Water mains and fire hoses ...
