LFR-IR Sensor Card Circuit diagram. Our LFR has two infrared sensor cards (left and right) on the bottom of the chassis for detecting the black tracking indicant on the path. Each sensor card is a ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now ...

Building line following robots is fun and easy. Building a line-follower that is this tiny is a different story. The surprising thing for us is that despite how it looks, this robot whose name is R… ...

It has a distance sensor to calculate the distance to walls and objects, an accelerometer, light-sensing phototransistors to seek out light or dark, edge detection sensors, infrared transmitters ...
