Autonomous robot for precision ground marking

Autonomous robot for precision ground marking

The construction industry is gradually  adopting new technologies to enhance its productivity and overcome the global shortage of construction workers. Thus, to assist in the automation of construction tasks, robotic systems specifically designed for ground marking have been developed to produce detailed patterns on various surfaces. However, these systems typically have limited repertoires of available markings and lack the ability to create a wide variety of patterns with sufficient precision. This paper presents the development of a prototype of a mobile, wheeled robot capable of autonomously executing diverse designs on surfaces such as fields and floors. The robot’s potential applications include use in construction sites, roads, sports fields, and exhibition halls. It marks the ground using a plotting pen while navigating and avoiding obstacles within its environment. Additionally, the robot can produce a range of drawings, including letters and signage, and its capabilities can be extended to create decorative patterns as well as marks for floor-based games. This robot was constructed entirely from cost-effective, commercially available. We has tested the robot extensively, demonstrating its ability to perform complex markings with high precision and consistency. As such, this work contributes to the field of automation in construction by introducing a versatile and cost-effective solution for ground marking. It is an omnidirectional wheeled robot with a pen plotter. The robot shows an accuracy of  ±2 cm.
