I. INTRODUCTION

Agriculture has long been a pillar of human society, with technological innovations constantly changing food production and resource management. Precision agriculture (PA) seeks to optimize agricultural inputs and outputs using technology to increase crop yield while reducing environmental effect. Robotics in Pennsylvania has emerged as a critical component in meeting global food demand and environmental issues [1-5]. This article looks at the evolution of robots in precision agriculture, comparing old mechanical methods to cutting-edge developments. Traditional agricultural robotics, which concentrated on duties such as planting, harvesting, and irrigation, laid the groundwork for the mechanized age. However, the emergence of revolutionary robots has brought unparalleled capabilities, such as autonomous decision-making, real-time data collecting, and task-specific automation using machine learning algorithms.

Traditional techniques, which rely on manual and semi-mechanical systems, are increasingly being replaced by autonomous systems powered by artificial intelligence (AI), the Internet of Things (IoT), and sensor technologies [6-10]. This research presents a comparative examination of these developments across numerous aspects, including efficiency, flexibility, cost-effectiveness, and environmental impact. Furthermore, the problems and opportunities involved with using novel robots in various agricultural contexts are examined, offering a thorough picture of how technology is altering modern agriculture. This study assesses improvements in robots for PA, contrasting conventional systems with current innovations.

II. TRADITIONAL ROBOTICS IN AGRICULTURE

A. Mechanized Systems

In the field of precision agriculture, traditional robotics in mechanized systems plays a vital role in streamlining agricultural processes. Traditional agricultural robotics systems have been employed in tasks such as planting, irrigation, harvesting, and soil monitoring. These systems utilize various mechanisms such as autonomous tractors and harvesters, typically designed to improve efficiency and reduce the labor force in large-scale farming. For example, research on robotic harvesters[11] has demonstrated the value of increasing speed and accuracy in the harvesting process, significantly reducing the manual labor required. These traditional systems are often highly durable and efficient in straightforward agricultural tasks. However, the focus on mechanical components often limits the flexibility of these machines, especially in irregular terrains or more complex agricultural activities[12].

Moreover, traditional robots typically depend on predefined programming, which restricts their ability to adapt to varying conditions or diverse crops. Despite their initial limitations, significant advancements in control systems and sensing technologies have enhanced the capabilities of these robots[13]. For instance, integrated GPS systems, cameras, and sensors in some traditional machines have been used to improve precision in tasks like irrigation and crop spraying[14].

However, as modern agricultural practices evolve towards more data-driven, smart technologies, the demand for innovative robotic systems that incorporate machine learning, real-time data processing, and advanced AI has been on the rise. Innovative robotics in agriculture now go beyond mechanical systems to incorporate high-level automation that can adapt to changes in the environment. The increasing use of drones and sensors for precision farming and autonomous decision-making systems is leading the shift towards smarter agricultural solutions[15]. These new systems are better equipped to handle the complexity and dynamic nature of modern farming compared to traditional robots.

Recent studies on robotic technologies[16] indicate a rapid transition from purely mechanical systems to more intelligent, sensor-based innovations. These modern robots can assess soil quality, detect pests, and even analyze plant health using AI algorithms. Furthermore, with improvements in machine learning, robots can now perform tasks based on real-time data, enhancing their efficiency in precision agriculture.

Comparatively, traditional robotics systems are limited by their inability to process large datasets or change operational modes without extensive reprogramming, making them less adaptable to the diverse needs of modern agriculture[17]. Meanwhile, newer systems such as those that utilize AI are becoming increasingly autonomous and capable of handling multi-tasking scenarios without direct human intervention, offering far greater scalability and precision in farming operations[18].

B. Limitations

Traditional robotic systems exhibited significant limitations:

1. Technological Constraints: While the advancement in robotics for precision agriculture has shown promising results, many traditional systems still remain more cost-effective and accessible for smaller-scale farms. As discussed in[19], the technological sophistication of innovative robotic solutions often comes with a high initial cost, which can be a barrier for widespread adoption among farmers with limited financial resources.
2. Operational Complexity: Many innovative robotic solutions require a high level of technical expertise for operation and maintenance, limiting their practicality for rural farmers without advanced training. This issue is highlighted in[20], where it was noted that the need for specialized training to operate newer robotic systems could reduce their utility in the field. Traditional systems, in contrast, tend to be simpler to operate and maintain.
3.  Integration with Existing Infrastructure: The integration of advanced robotics with existing farming infrastructure and machinery can be a complex and costly process. This is further discussed in[21], where it was observed that traditional systems often have better compatibility with existing agricultural equipment, making them more adaptable for immediate use.
