Introduction
Traditional road painting methods are labor-intensive, time-consuming, and
often expose workers to hazardous conditions. The Autonomous Road
Painting Vehicle offers a sustainable solution for maintaining road
infrastructure with improved efficiency, safety, and cost-effectiveness. Its
integration into existing road maintenance processes can lead to enhanced
road safety, reduced maintenance costs, and improved overall road network
quality, ultimately benefiting communities and transportation systems
worldwide.

Objective
6
The main objective of this project is to Autonomous Road Painting Vehicle for
The main purpose is to create a smart robot so that we can take many benefits from
one project.
 To vital for maintaining clear and consistent road markings, which are essential
for road safety and efficient traffic flow.
 To minimize the exposure of human workers to potentially hazardous roadwork
environments.
 enhances operational flexibility, allowing operators to manage the robot from a
safe distance
 to provide a user-friendly interface, typically accessible through mobile apps or
web dashboards

 Define the project objectives and requirements, including the type of road markings, robot
specifications, and performance criteria.
 Create a conceptual design of the road marking robot, considering factors like size, mobility, paint
dispensing mechanism, and sensor suite.
 Select the necessary components, including Arduino board, Bluetooth module, motors, sensors (e.g.,
ultrasonic), wheels, paint dispensing system, and power source (e.g., Li-Po battery).
 Design the physical structure of the robot, including the chassis, mounting for sensors, wheels, and paint
dispensing mechanism.
 Wire the selected components together, ensuring proper connections, voltage regulation, and power
distribution.
 Develop the software for the Arduino board, implementing control algorithms for navigation,
Bluetooth communication, obstacle avoidance, and paint dispensing.
 Test the robot's individual components and subsystems to ensure they work as expected.
