LFR: A segment of competitive robotics

 LFR: A segment of competitive robotics


◉ What is "Competitive Robotics"?

        The use of robots in competitive events or contests is referred to as competitive robotics. Teams of students, amateurs, or professionals are challenged in these competitions to design, construct, and program robots that can successfully accomplish a number of challenges.

Robot races, in which robots compete to complete a course as quickly as possible, robot wars, where robots engage in combat in an arena, and a variety of other challenges where robots must perform particular tasks, like navigating mazes, picking up objects, or completing obstacle courses, are just a few examples of competitive robotics.

 ◉ What is "LFR"?

        Using sensors and programming to direct its movement, "LFR" is a form of robot that is intended to follow a line or track on the ground. The full form of "LFR" is "Line Follower Robot". To move materials along a production line, these robots are frequently used in industrial environments like manufacturing plants. In competitive robotics, they are also popular.

◉ LFR in competitive robotics:

        In competitive robotics, a line follower robot is a type of robot designed to compete in events. These events typically involve a series of challenges that the robot must carry out while following to the line, including avoiding curves, junctions, and obstacles. The objective of the contest is to finish the track as swiftly and accurately as you can.

 ◉ Types of LFR:

    There are different types of LFR. Such as,

       ▣ Arduino based Line Follower Robot.

       ▣ Raspberry Pi based Line Follower Robot using.

       ▣ MSP430 Launchpad based Line Follower.

◉ How a LFR is made?

    According to the intended performance, level of complexity, and resources at the creator's access, a line follower robot's construction can vary. Making a line follower robot, however, generally involves the following steps:

       ▣ Designing the circuit board of robot's body.

       ▣ Designing the sensor circuit board.

       ▣ Assembling and soldering components to the circuit board.

       ▣ Short circuit test.

       ▣ Programming the robot.

       ▣ Sensor calibrating.

        ▣ Testing on track. 

LFR (Line Follower Robot)

◉ Components needed to build LFR:

      ▣ Microcontroller: The part of a robot's intellect in control of it. For LFRs, popular microcontrollers include the Arduino, Raspberry Pi, and PIC.

      ▣ Wheels and Motors: These parts help the robot to move along the track. Mainly, DC-gear motors are used to drive the robot.

      ▣ Motor driver module: Motor driver module helps the bot to control the RPM and direction of motors. The circuit amplifies the signal from the microcontroller and sends it to the motors.

      ▣ Sensors: Sensors help the bot to detect the line. Mainly IR sensor is used to detect lines. For example, TCRT5000, LTH-1550 etc.

      ▣ Power source: A stable power source is a must to run LFR. Generally rechargeable battery packs are used as power source.

      ▣ Connectors: Connectors are needed to create connections between modules and sensors of LFR.

      ▣ Resistors and capacitors: To reduce noise, ensuring proper flow of current and to limit the current flow, resistors and capacitors are indeed.

      ▣ Chassis: A LFR's chassis is its physical structure, which houses all of its parts.

      ▣ Breadboard: Before completing the design, the electronics is assembled and tested on breadboard.

Down the sweet memory lane with my Dadu

Written By Tasnia Ahmed Chowdhury Picture collected from Pinterest                                               "Man is mortal" - a fact that we often get to hear in our life. We only realize how cruel this fact is when we lose those people in our lives for whom we feel the deepest love from our hearts. When we lose the people with whom we find solace in our life and when we realize the love and care they gave to us were something priceless which can rarely be found from another person, only then the pain of losing one's dearest one hits us more than the pain of other things. The first time when we realize we lost that person forever we only grieve their death but as days pass by with their absence our grief comes from the yearning for the lost unconditional love they had showered on. One such person whom I lost in my life was my granny whom I used to call 'Dadu'. Having both working parents much of my early childhood was spent with my Dadu. She left this world a

The Quantum World

Image
  The Quantum World The quantum world is a mysterious area of science that defies understanding of the laws of classical physics and explores the behavior of matter and energy at a microscopic level. Quantum mechanics describes the behaviors of subatomic particles such as electrons, protons, and photons. Quantum mechanics was discovered by a group of physicists in the early 20 th century. Some of the famous physicists were Max Plank, Albert Einstein, Neils Bohr, Werner Heisenberg, and Erwin Schrodinger .                                                                                                                 Some mind-blowing quantum theories: Schrodinger’s Cat The Schrodinger’s cat was a thought experiment proposed by Erwin Schrodinger in 1935 to illustrate bizarre and counterintuitive implications of quantum mechanics. According to his experiment, a cat is placed inside a sealed box attached to a device that can release lethal poison to kill the cat. The release of

How to have an amazing holiday in Malaysia

Image
Steeped in history and culture-there is never a dull moment for the inquisitive traveler. From the buzz of city high fashion, trendy hot-spots and modern cuisine, a natural escape is never far away. Be it sandy beaches or highland rainforests, a visit to the many spa or country resorts in  Malaysia  is a must. Malaysia  a country, which really surprised me! It's a place in contrast; where you can hear the mosque's call to prayer in the morning and sip cocktails at a fancy nightclub in the evening. Where you can trek through the jungle one day and sit on a beach the next. It is one of the most visually striking country in South Asia. It has a bustling capital( Kuala Lumpur), thick clouded forests of the Central Highlands, and fantastic islands bobbing in crystal clear waters off of pretty much every coastline in the country. Top this fantastic diving, and Malaysia is dressed to impress visitors. Malaysia is roughly split into two sections. Peninsular Malaysia, which only shares
