Introduction: Simple Line Following Robot
the simple robot is based on LM393 Dual voltage comparator
The function of the circuit is to match with the photosensitive resistance, and to provide a suitable reference voltage for the LM393 chip.
Because of the different black and white reflectance, the photosensitive resistor will change. In the circuit, allocated to the different resistance voltage different This robot is mainly used to work with this little skill.
Step 2: The Control Board Based on LM393
led + place and the resistances
Step 3: The Sensor Board(LED)
the led “+” are in the middle,the long pin is "+"
Step 4: Sensor Board(Photosensitive Resistance)
Because of the different black and white
reflectance, the photosensitive resistor will change. In the circuit, allocated to the different resistance voltage different
Step 5: Connet the Mother Board and the Sensor Board
Step 6: The Two Motors
Step 7: The Wire
red to ‘+’
Step 8: The Chassis
The bottom four screws, first installed on the diagonal of the 2, and finally install the remaining 2
Gently adjust the tightness of each screw to ensure the bottom level
Can not be too hard, or the bottom of the plastic film will be broken
Step 9: The Top Four Screws
The upper right corner of the need to pad a piece of paper to prevent short circuit
Step 10: Battery and Charging Board
Step 11: Mini Wheel
Step 12: Fix the Battery and Sensor by Glue
Step 13: Test
When you have done all
Draw a thick black line 1.5cm
Put the robot on the top.
Adjust the 2 Blue potentiometer, you can follow the black line running robot
