This is my 5th robot. He is Cruddy version 2. Still he is a line following robot but has now abetter circuit design (originally designed by me) and has cool appearance 😀 This project doesn’t have any microcontroller. It is designed through digital logic gates only. I used two Light Dependent Resistors (LDR) as my sensors.
Main components used:
2. 78LS04 / Hex Inverter IC
3. L293D / H-bridge IC
The driving system used here was Differential Drive System. No programming codes required only pure electronics and logic circuits.
I posted here the schematic I designed:
