The line-tracking robot is a device that has a capability to recognize and track a path which might be visible such as a drawn line on a surface where the robot differentiates white-area and black-line of high contrast colors, or invisible like a magnetic field.

In this module, each team assigned to design a line-tracking robocar by using Infrared sensors (IR). The sensor will be attached at the bottom of the robocar. The sensor will determine if the line under it is shifting towards its left or right as the sensor move over the line. Based on that calculation, it gives respective signals to the motors to turn left or right so it corrects the wrong moves using the feedback mechanism to make the robocar follow the line exactly. The output of IR sensor is a digital signal and it enables Infrared sensors to be assembled with any microcontroller such as Arduino Uno.

The other challenge in this project is to design and assemble the gripper as well as to control it manually to pick-up the right color ping pong ball and place in team’s bucket. And that would be done by using servo motors to give the availability to freely- control the gripper toward any degree.

The difference between this project and others that 3D printing design of the gripper will be as one part and each of the servo motor, wires and screws will be placed into the gripper.
