Linbot advanced line following robot




Linbot is an advanced line tracer robot. It has one pair of infrared emitters and sensors directed forward, as well as three pairs of infrared emitters and sensors directed downward. Linbot can follow a black line placed on a white floor as well as a white line on a black floor.

When it meets with an obstacle while following the line, it makes a U-turn and continues on.

It comes in kit form, allowing the user to acquire hands on experience in robotic principles.
