Robo Jr. Light

Robo Jr. Light is a basic light tracer.

It follows a light source such as a torch. It has two photo sensors, one on the front right corner and another on the front left corner. Two motors power it.

How does Robo Jr. Light work?

Robo Jr. Light has two CdS (Cadmium Sulphide) photo sensors.

More Information

These sensors receive light where it is converted into an electronic signal. This signal travels to a logic IC (Integrated Circuit). The logic IC generates control signals for the two motors. When the both sensors detect light, the robot goes straight. When the left or right sensors detect light, the robot turns towards the source and continues on.
