I saw someone else had the idea of a brainless line following robot. The creator of it was BigRick. Click on the link to see his design. https://www.robotshop.com/letsmakerobots/node/8396. This was my insperation to create the Zombie Line Follower. I was looking at his and I saw some ways to improve it. Instead of only two sensors why not have four. The extra sensor act like "Safety Net" incase the first pair miss it. There is also a variable resistor to control the ir emitter to dim and to bright. The sixty-five ohm resistor acts as a "Safety Net" if you where to turn it all the way down. The toggle switch is wired to swap the motor to change line color such as a black line with a white background and vice versa. To build follow theschematics at the top of the page.
Componant List:
- 4x Fairchild QRD1114 Reflective Object Sensors or ir emitter and transistor
- 2x 10kΩ resistors
- 1x 65Ω resistor
- 2x PNP transistors
- 1x Toggle Switch
- 2x DC motors
- 1x 9V Battery holder
- 3x colored l.e.d.s
- 3x colored l.e.d.s
Line Follower
- Power source: 9 Volt Battery
- Sensors / input devices: Reflective infared sensor
- Target environment: indoors
