A lot of Line follower robots exist in the world today, building one is tough especially if you are not familiar with programming.
The robot is home-based and moves around, made possible by two independently powered wheels, a third wheel balancing it, a power source, some logic circuitry, some sensors, and remote control. To know how the technologies work, first, buy the various parts, assemble them, program it to have your own.
The line Robot Kit is less expensive, with fairly high functionality. You have to build it after purchase but will take some time like 10 minutes following the instructions on the manual.
One of the major features of this Robot is that key assembly needs to make the robot to either obviated by design or made easy by using handy dandy cables.

Components of line follower robot

Generally, making the robot start with a controller board. These boards have little thingies to attach wires, which are lined up and organized in a way that you can also attach a “shield” consisting Pre-fab circuitry to do a unique thing. The motor control shield is one of the kind. Others ease infrared communication or blue-ray communication.
The core of the robot is the chip joined with the same board as motor control and the IR communication circuit. A couple of sensor boards and blue tooth board can also be added if you so desire; both boards are separate which allow you to swap the sensors or communication devices that come with the robot.
The motor regulates parts of the board secured to the motors with simple cord; all screwed to the chassis, holding together the controller, brain, some sensors, and the wheel.
The Line follower robot has an inbuilt programme that allows you do things right out of the box.
Most line follower robot comes with a remote, to send motion commands, and other fun commands, to the robot via an IR system. Where you built one yourself try other remotes on the robot and see if you get a rise out of it.

Operating the line follower robot

The robot is operated in different modes one of which is the “object avoidance mode.”You can initiate this with an on-board button, or through the remote. The machine has a sensor on the front that transmits an ultrasonic signal, and then secure it, using the time to evaluate, determining how far the nearest object is, in its front.
As the robot moves closer to an object, it stops, and turn course.
This sensor does not notice when the robot is at the top of the stairs.
A second mode is the “line follow mode.” This includes a pair of sensors at the front of the robot, facing down. The sensor detects colour contrasts, and, can determine if the robot is over a line, using an inbuilt programme to follow the line. The kit has a big piece of paper with a black figure eight on it, to test or when using this mode.
You can also to draw your own lines, but you will discover that human senses differ greatly from the robot senses, so what you think is a dissimilar line may not be what the robot thinks.
If you find the line following not good enough, purchase a more sensitive sensor, and reprogram the robot to suit your purpose.
This robot is fragile and can be replaced inexpensively. The undercarriage is designed to connect many things to it. You can find components that will relate with this system from most robot hardware stores
You don’t have to know how to programme to make this robot and enjoy it, but a basic knowledge of programming will make it a lot easier, and this is conceivably one of the perfect ways for a kid to study hardware and some software skills.
