Line Following Robot circuit


Posted on Feb 6, 2014

The motors will be driven from the full source voltage, so make sure this isn`t going to make your robot too fast! Firebot has GM3 motors driven with a 9V battery, however the circuit differed and the motors were only driven by 5V from the voltage regulator. The line detectors drive the relays on or off dependant upon their status, remember that t

he left line detector should drive the right motor and vice versa. The obstacle detector enables/disables the inputs on the line following chip. This is made possible by the fact that the chip has two sets of inputs, both with their own enables. The obstacle detector uses the second set of invereters which is grounded (enabled) constantly.
