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 ...

When comparing the Raspberry Pi and Arduino ... such as IR distance sensors, pressure sensors, and even simple potentiometers ...

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 ...

The Bolt also sports four infrared sensors ... an ambient light sensor, and a better battery for up to two hours of heavy use play time (perhaps longer if performing simpler moves) before needing ...
