The Robo Junior kits come with clear, easy to follow directions. They can be ordered with the circuit board either assembled (no soldering required) or unassembled. These robot kits are ideal for someone just beginning to explore the world of robotics.
Robo Jr. is a basic line-tracing robot. It follows a path laid out for it along a floor or other smooth surface. The path must be a dark line on a light background. The colours are not important, but it will not work if there is not sufficient contrast.
Robo Jr. has two infrared emitters on it front along with two sensors. One pair is on the left, the other on the right. Each emitter projects infrared light onto the floor. The amount of light reflected back from the dark line differs from that reflected from the floor; thus it can tell where the dark line is. Each sensor controls a motor, enabling it to follow the line.
