The HW-006 (V1.3) line tracker sensor module based on TCRT5000 an infrared reflectance sensor. This is usually mounted at the bottom of a line following robot chassis. This compact tracking sensor ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

The robot uses a whopping 32 IR sensors to follow a black line across a concrete workshop floor, adjusting its path using a steering motor salvaged from a power wheelchair. An Arduino Mega Pro ...
