All about Robotics


The first robot was unarguably Mechanical Knight designed by Leonardo da Vinci in the year 1495. As displayed by Leonardo in the court of Milan, this robot could move its limbs and head. But in the year 2013 the field of robotics has become vast and word robot is no longer limited to refer a  humanoid that perform certain tasks similar to that of the humans. Scope of robotics is becoming vast and vast with its application crossing the boundaries of imaginations of our human mind. Like mobile phones and laptops robots will be very much a part of our lifestyle. Today, robot is part of almost every industry like defense, medical research, home utility, food, manufacturing, and list is long. Take any like - drone that are designed as unmanned vehicle, or painting robot in a automobile assemble line that can paint a car body in 50 seconds, or any other robot. 

Robots not only improves efficiency, but can do job that are on explored by human beings. Some home grown robots (MINDSTORMS NXT) are capable of solving complex challenges like rubix cube in less than 5 seconds. Robotics stands at a point where computers were almost a decade ago. Lot of work has been done in industries, but still reach is not more than 0.1%. 

Industry will grow exponentially and will need expertise to sustain the growth. Lot of initiatives are being taken to help students take up this challenge, not only by learning robotics in early age, but also learning application of mathematics and science concepts in form of robotics. 

There is multitude of robotics kit available in market for students to learn robotics like LEGO MINDSTORMS NXT, VEX, BIOLOID, etc.  These kits are simple to use, and come with sensors and motors.  LEGO MINDSTORMS NXT is most popular kit due to its cost advantage, but VEX is a good kit for advanced users. Students can design Robotics Projects and give their imagination a shape using these kits. RoboGalaxy offers a comprehensive online education on robotics. RoboGalaxy provides education at three levels depending on age group – elementary, junior and senior. RoboGalaxy also provides coaching for international competition like World Robot Olympiad (WRO), FIRST LEGO League (FLL) and provides a window of opportunity to show case talent at international arena. 

Learning robotics in early age not only helps students implement STEM concepts, but also, they can go for higher education into this niche area. Almost every university in United States of America offer robotics projects either for Undergraduate or Postgraduate students.

What is Humanoid robot ?


A HUMANOID ROBOT is a robot with its overall appearance based on that of the human body. In general humanoid robots have a torso with a head, two arms and two legs, although some forms of humanoid robot models may have only few parts of the human body, for example, from the waist up. 

Some humanoid robots may also have a 'face', with 'eyes' and a 'mouth'. Androids are humanoid robots built to resemble a male human being, and Ganoids are humanoid robots built to resemble a female. Androids resemble humans, usually both in appearance and behavior. The word android has been used to denote several different kinds of artificially constructed beings: a robot that closely resembles a human; a cyber; or an artificially created, yet primarily organic, being that closely resembles a human. A humanoid robots generally operate through LEGO,NXT and MINDSTORMS.

Components of a Robot




Any machine which can be called as a robot will be composed the following basic elements:
- Motors: Most of the robots perform some mechanical functions. In order to perform these tasks electric motors, a hydraulic system, a pneumatic system or a combination of all three. The electric motors often have feedback mechanisms. 
- Sensors: To detect any event and react accordingly, robots need to continuously scan their environment and collect information while they are in active state. A robot does that by using sensors such of different type like colour sensor, light sensor, touch sensor, sound sensor, ultrasonic sensor, etc…
- Power supply: The motors and other actuators of robot require uninterrupted power supply when it is active. Most of the robots use rechargeable batteries to power up their motors and sensors.
- Controller: It works as the brain of the robot and controls the behavior of robot by controlling all other components. The controller is programmed so that the robots behave in the manner required by their programmer/user.
- Moving Mechanism: which may include wheels & gears, Biomechanical parts such as limbs, etc…
