Battery
In this section of our tutorial, you will understand about battery capacity, how long will it run, and other parameters. For example if the motor at the no load condition (which means you have not connected to any wheel or any gear to the motor shaft) is consuming 0.2 Amps and you are running the motor using 12 volt 1.3 Ah battery, now the motor will run for [1.3 (Ampere-hour) / 0.2 (Amperes)] will results in 6.5 hours, now...
Direct Current (DC) vs Alternate Current (AC)
In the line of robotics tutorial, we will see about AC and DC in this section. Almost all electronic components runs on DC, to understand it in simple terms, first let us know about how electrons flow in DC and AC using some small examples. Assuming, we have battery and a motor in which motor is connected directly to the battery after which the motor runs. Now if you watch closely the electron flow, it is very well known that...
Father of Robotics
It is very well known that large amount of Greek texts were translated into Arabic language at the time of Abassid Caliphate (8th century to mid 11th century ), primary motivational factor for all these works was the establishment for Bayt – al – Hikma (Hikma – wisdom, Bayt – House, House of Wisdom), and also the library Khizanat – al – Hikma (Khizanat- Treasure, The Treasure of Knowledge). It has been said that close to...
Etymology of the word ‘Robot’
You will never get bored when you ponder on something which you like the most. Am I right? Yes, now we are going back to history without the help of time machine to find out how the word Robot came into existence. In the ancient period, robots were playing a vital role only in science fiction stories. In 1817, Mark Shelley, a novel writer, wrote a story named ‘Frankenstein’ in which there was a character looking like a humanoid...
World’s First Industrial Robot
Robot is an automated machine which was booming only in science fiction stories and movies till 1950’s. Even the name ‘Robot’ was first used for characters of artificial creatures in a stage drama directed by Karel Capek in 1920. Isaac Asimov, a well-known writer, has written three famous laws only during the period of science fiction era. So, when did the first robot came into action? What kind of robot it was? Where it was used? Who...
How Servo Motor Works?
Before we look at the working, let us look at the basic components of servo motors: A Controlled Device A Output Sensor A Feedback System A servo motor can usually rotate 45˚, 90˚, 180˚. Servo mechanism is an automatic closed-loop control system in which the device is controlled by a feedback signal (instead of variable input signal) using the comparison of output signal and reference input signal. How Servo Motor Works? When you open...
