A robot built with littleBits that follows a drawn line and serves treats from the snack bowl mounted on top.
How it works:
The Line Following Snack Serving Robot is a robot made with littleBits that does exactly that, serve delicious snacks along a path drawn by the maker. This project requires no programming.
The robot has two DC motors controlled by a respective light sensor. The bright LEDs illuminate the surface below the robot and more light reflects from the floor surface than from the drawn line. When the bright LED shines on the floor, more light reflects into the light sensor telling the DC motor to turn fast. When the bright LED shines on the drawn line, less light reflects into the light sensor telling the DC motor to turn slowly. Each light sensor controls its respective DC motor in effect steering the robot along the drawn black line.
The inspiration for this project came from one of our active users on the project’s portion of our website, Yoo-bin Lee. She created the original littleBits line follower robot in December of 2013.
