DIY Open Source IVRS System

This project is an Interactive Voice Response System based on a personal computer. The data of an institution or firm is stored in a computer as a MySQL database, the world’s most popular open source database.Parents or students can then access and retrieve data from this database just by making a call to a predetermined mobile number. The user should provide the student details like admission number, semester number, exam code etc. when requested by the computer. The computer will then speak back the data requested, using a speech synthesizer. The Block diagram is given below:

Roller Robot- A Clone of Recon Scout

                    It was a video about a reconnaissance robot called Recon Scout  that inspired me to design a clone of it. Recon scout is a rugged, stealthy and  mobile reconaissance robot which can be thrown through a window, over a wall, or down the stairs and it lands ready-to-go. You can even drop it from an unmanned aerial reconnaissance vehicle. Once deployed, you can control its movement at a distance using a hand-held operator control unit.

Simple Homebrew Robotic Gripper from Junk Parts

Grippers are an important part of robots. Often they are used in gripping and taking objects and play the most important role in robotic arms. Most of the grippers cost much money and may not be easily affordable by hobbyists. Then the best option is to build your own gripper.When it is from the so called ‘useless junk parts’, it becomes more interesting. So let us dive into more  details.
