Hirai-san has won many line follower robot contests. There are then two further runs where the on-board computer can make use of that map to run each section as fast as possible. During the first run, the robot learns and maps the course. The frame is made of a hard plastic with 174 mm length and 110. The frame enables the motors, sensors, motor driver used in the line-following robot to stay as a whole. Wheels with a diameter of 65 mm have been used to obtain high torque and minimize the effect of disturbances caused by the track. Please take a look at the video that I've been uploaded. the robot’s tracking capabilities of the path. I assume many people has already knew the working principle of this car. The sensors are detecting the color, the arduino processing the read of sensors, and then tell the motors to move as it is. ìChallenge 1: Can you write a simple line followerHint: Review Beginner: Basic Line Follower lesson ìChallenge 2: Can you write a smoother line followerHint: Change how sharp the turns are in a simple line follower. In this video, you can see the All Japan contest winner. Therefore, calibration of the reflective optical sensor outputs is an important procedure for a fast line-following robot. So, this car/robot will follow the contrass-colored line on the floor wherever it goes. The whole thing can be built in an afternoon and run around on a table top using aline drawn with a marker pen on a piece of paper.Īt the highest contest levels though, these are sophisticated, fully autonomous robots that can learn complex course layouts and run them at great speed. The simplest line followers can start off with very simple components, a couple of motors and no on-board computer. The IC gives high output when IR LEDs detect some object in front of it (or in our case, detects white light). The IR sensors give the output to LM358 comparator IC. Keywords: Robotics, Line following robot, IR Sensor, LED. The line following bot works on simple logic obtained by combing the comparator circuit working and L293D motor driver working. For special situations such as cross overs where robot can have more than one path which can be followed, predefined path must be followed by the robot. Robot must be able to detect particular line and keep following it. Lessons learned from building line followers form a valuable basis for more advanced robotic topics making these ideal beginner projects.ĭon’t be fooled into thinking there are not real challenges available for the line following robot builder. The two types of line following robots include the black line follower and the white line follower. Line follower is an autonomous robot that follows a line, either a black line on white surface or vise-versa. These kinds robots have very real applications in factory automation and other industrial settings. In this resource, you will turn your robot buggy into a line-following robot buggy so it can whiz around a track with ease. Line followers typically detect a contrasting line laid out on the ground or a table top and try to run around following that line as closely as possible. Line following robots are often one of the first things the budding robot builder wants to try.
