  1. 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 ).

  2. Comparison between readymade robot kits (Asuro, Boe-Bot, Qu-Bot, Ma-Vin)

    I have 4 programmable robot kits here is a small comparison between them.

    1. Asuro

    I bought this robot from hongkong for US$ 55. A good price for beginner robot. It came with serial port transceiver but my lapy had no serial port so i tried it when i came back to India. This is based on AVR. It comes as a soldering kit. You have to prepare program in any compiler for avr

    Pros :
    Low price
    Easy to assemble
    Open source

  3. Robot Dynamics - Getting the Specs Right

    Well this article covers the dynamics involved in making a good robot! So letís see what are the dynamics involved in making a perfect Robot there are many factors that can affect like RPM torque of the motor, diameter of the wheel friction between the tyres and the floor etc. We shall discuss how to calculate your requirement and then proceed into its application. For that youíll need to brush up your knowledge of kinematics and dynamics the first few pages explain the conceptís involved if you ...

  4. 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.

  5. Of robots and toys

    ::

    I remember the technical fest at NIT calicut some years ago. must be two or three. I checked out the robot soccer competition. I was not very surprised, every one had the same old toy gear set, ripped off from the famous 'earth mover' toy, wire controlled. I could hardly find ANY electronics. It was not a good sight at all. Something is terribly wrong. Somewhere. One of my students, i think the same year, made a painfully slow line follower cum obstacle avoider. I remember ...
