Quadrocopter : Some Basic Concept

QuadroCopter

Quadrocopters, also known and quadrotors, are one of the most interesting little flying machines ever imagined; yet there's a load of disperse and almost undecipherable amount of information that comes from hobbyists' and builder's gut feeling on what seems to be the right thing to do.

Line Follower Robot (Enhanced Version)

 

Overview

        This small line follower robot, was designed to be easily built at home without any special equipment, and using a minimum number of mechanical parts. You wont need more than 2 small motors, 2 free wheels and a piece of pcb (to hold the micro-controller, the motors driver and the line sensor) and sure.. your soldering iron!

    The main trick making this design simple and affordable, is that the robot's chassis is actually the main board of the robot, where some supports for the wheels - also made of small parts of copper boards - are soldered to it. All the motors, and the skids are mounted on the main PCB. For an electronics hobbyist, PCB manufacturing is a skill that will be learnt sooner or later, so this design lets you use your experience in PCB manufacturing to design a high precision chassis for your robot.

Line Following Robot (MICROCONTROLLER AT89C2051)

Build your Own Line Following Robot !!

This Project Line Following Autonomous Robot is based on 8 bit Microcontroller AT89C2051. This Robot follows the black line which is drawn over the white surface or it follows the white line which is drawn over the black surface. The infrared sensors are used to sense the line. When the infrared signal falls on the white surface, it gets reflected and if it falls on the black surface, it is not reflected this principle is used to scan the Lines for the Robot.

Boston Dynamics Developed Dynamic Robots & Its software for Human Simulation !!!!

 

Boston Dynamics, an engineering company founded by Marc Raibert and his colleagues in the year 1992, have developed dynamic robots and its software for human simulation. Several innovations were made by them college life in Massachusetts Institute of Technology. They excelled in the field of robotics and developed robots that could run and epitomize all basic characteristics of animals.

       Lately, the researchers at the Boston Dynamics lab developed an anthropomorphic robot called Petman. It is a two-legged, upright robot designed to stand and walk like a man. The main aim of the machine is to test chemical warfare clothing for the US army. The robot replicates the same motion of a human being and is able to move at a speed of 3.2 miles/hour.

      Besides the regular motion of the robot, it has also been programmed to demonstrate some basic workout methods like – treadmill walking, push-ups, squats, lunges and some simple calisthenics. From the video below, you can see the robot balancing itself when it is pushed while running on the treadmill. It took almost 15 months for the designers to design this wonderful machine, and 15 more months to build it.
