by , 04-12-2011 at 07:36 AM
What is PID?

Ok so what is this PID and why is it much talked? Well, PID means proportional–integral–derivative and it is a control feedback method applied in different control systems, its main task is to minimize the error of whatever you are about to control. It is superior quality error control feedback mechanism and the general industry standard. Speaking simple it takes in the inputs ...

2. #### Competition Robotics - General Purpose high performance robot (Part 2)

by , 02-20-2011 at 08:26 PM
In the last part we had gone over some ground work on how to build a fast robot. If you had missed it you can read it here.

So this time lets start with some robot building, like in previous article our target was a fast, small robot capable of solving problems like mazes , line following , soccer , picking and dragging things etc. When building we will go over the headings covered last time and pick items appropriately. The best commercial example of a robot which somewhat fulfills ...

3. #### Competition Robotics – Building to Win ( Part 1 )

by , 02-04-2011 at 08:03 PM
Ive run Robotics India since a few years now, I can say about 80 % visitors are looking to take part in a competition. But most people end up building the same old robots making the same mistakes year after year and I am not really seeing any improvements in robots which participate in this competitions. So I thought to start a series on how to build better robots for most of these competitions with some tips to help you win. Proposed specifications are of target robot which should be able to ...

4. #### RiDuino Projects: Playing the National Anthem Using Piezo Speaker

by , 04-16-2010 at 09:43 PM
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) ...

5. #### RiDuino Installing Drivers for Windows , Linux or Mac

by , 04-07-2010 at 10:52 PM
Riduino emulates a serial port on USB using Atmega8 to help connect the Arduino loaded controller to your PC. This is done through a CDC Driver.

For all Files,Schematics and Downloads related to Riduino visit - http://www.roboticsindia.com/wiki.php?/page/riduino
Windows

So lets get started by installing the driver. Just Connect Riduino to your PC's USB port , The TX RX Led should blink twice and then Windows will popup the New Hardware ...
