firmware dependencies
The following libraries need to installed in Arduino
- LiquidCrystal I2C library by Frank de Brabander
- I2Cdev
Following a straight line
The robot follows a heading that is referenced to where it starts. To do this,
-
place the robot on the surface you want to paint
-
press the reset button WHILE THE ROBOT IS STATIONARY! There should be no movements or shaking.
-
The robot should follow a straight heading.
-
To stop the robot, press the ON/OFF button, or disconenct the battery
-
If using LCD, the screen should show the flow rate.
Paint system
The paint sequence is as follows:
- Once the robot is turned on, it paints at intervals of 5 seconds( this can be changed in the code. See code!). This paint sequence produces a dotted line
- Pump 1, pump 2 and solenoid are turned on at the same time.
- Flow rate is measured and displayed.
- Process repeats.
- You can increase the length of the dotted line by increasing the paint interval. (Again, see code comments for this)
ultrasonic designations
US1 -> Front ultrasonic US2 -> Right ultrasonic US3 -> Left ultrasonic US4 -> Resorvoir level ultrasonic
Ultrasonic Conclusion
Ultrasonic avidance is not necesssary in the real-world. Why are you painting a road with obstacles??
Flow meter interrupt pin change
The schematic show flow meter signal connected to pin 10. From tests, pin 10 cannot support interrupts. Please use pin 2 for the flow meter signal.( See code on flow meter Pin -> in defines. h. If you wish to change the pin to pin number 3).
Only pin 2 and 3 can be used for the flow meter.
LCD library installation
If you cannot find the Arduino-LiquidCrystal-I2C on Arduino Library manager, copy the Arduino-LiquidCrystal-I2C folder into your Arduino installation folder. You should be able to compile the code with no errors.

Questions
How big is the Road marking robot circuits PCB?
It measures 114.2 × 189.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Road marking robot circuits use?
65 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Road marking robot circuits KiCad files?
From the bytecod3/automated-road-marker repository on GitHub, at the commit this page was made from: the board is hardware-design/road-marking-robot-circuits/road-marking-robot-circuits.kicad_pcb and its schematic hardware-design/road-marking-robot-circuits/road-marking-robot-circuits.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Road marking robot circuits design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
