  1. Competitions Robotics 3 - The Build and a Fast Line Follower using PID

    Last time we covered the hardware we needed to assemble our robot. This time lets assemble it quickly and get it moving. And do some hello world in robotics , which is Line Following.

    We will start with the Video of what we are going to achieve -



    If you are building this and already have bought the parts I will assume that you will need little help assembling it , but I would like to give some pointers so that ...

  2. Beginners Robotics Guide : Basic Electronics - I

    The goal of this tutorial is to provide some basic information about electronic circuits. We make the assumption that you have no prior knowledge of electronics, electricity, or circuits, and start from the basics. This is an unconventional approach, so it may be interesting, or at least amusing, even if you do have some experience.

    So, the first question is ``What is an electronic circuit?''. A circuit is a structure that directs and controls electric currents, presumably to perform ...

  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 : Robot Types -Legged

    That is the first question that strikes anyone who wants to make robots to perform a task. By “type”, I mean the method of locomotion or movement of the robot. Legged or wheeled? How to choose among these ? Let me give you (or try to give you) a slight idea to help you out.

    There are many different locomotion types for small mobile robots. Generally,they can be divided into two types: legged and wheeled. Legged locomotion is very versatile but not as efficient as wheeled locomotion ...

  5. RiDuino Projects: Playing the National Anthem Using Piezo Speaker

    Piezo speakers are quite fun components. They can play as well as detect frequencies. The basic idea behind making them play tunes is to send a "Square wave" of the corresponding frequency. By Square wave, I mean , the HIGH and LOW time should be equal.

    How do we get the high and low time out of note frequencies?
    High time = Low Time = 1/(2*NoteFrequency)

    For Example, a basic C note (western musical notation) is 261 Hz. (http://www.phy.mtu.edu/~suits/notefreqs.html) ...
