History of Agriculture

The history of agricultural development can be traced back to the origin of human civilization. From the earliest hunter-gatherer stage to sedentary life and agricultural production, the development of agriculture is accompanied by the progress and evolution of human society.

Humans originally relied on collecting natural resources for a living, hunting wild animals and collecting wild plants to survive. However, with climate change and resource depletion, people are looking for more reliable food sources. About 12,000 years ago, humans began to explore the potential of agriculture and began to grow crops and domesticate animals.

Over time, people gradually improved farming techniques and methods. Ancient civilizations such as Ancient Egypt, Ancient Greece, and Ancient Rome developed irrigation systems, farming tools, and agricultural management practices that increased the efficiency and scale of agricultural production.

The development of agriculture in the Middle Ages was limited by feudalism and serfdom. Peasants are tied to the land, production methods are outdated, and agricultural production is relatively inefficient. However, improvements in agricultural techniques such as the introduction of the plow and rotation of crops, provided farmers with some improvements.

The advent of the Industrial Revolution completely changed the face of agriculture. The introduction of agricultural mechanization has greatly increased productivity. The invention of agricultural machinery and equipment such as steam-powered tractors and harvesters made farming more efficient and scalable. The widespread use of chemical fertilizers and pesticides increased crop yields, and agricultural supplies were greatly expanded.

Therefore, modern agriculture is committed to improving production efficiency, protecting the environment and promoting rural development. The application of new technologies, such as precision agriculture, agricultural robots and smart irrigation, helps farmers achieve sustainable agricultural production. The optimization of the agricultural supply chain and the improvement of the market mechanism also provide more opportunities for agricultural development.

So in the next 100 years, except for delicate harvesting of fragile fruits or complex decisions that require human judgment, human intervention may still be required, and other matters can be replaced by machines.


Autonomous Robot Weeder

An autonomous robotic weeder is a robotic device capable of autonomously weeding lawns and agricultural fields. Using advanced perception technologies, navigation systems and machine vision, these robots are able to identify and locate weeds and carry out precise weeding operations.

How an autonomous robotic lawnmower works typically involves the following steps:

– Perception and detection: The robot perceives the surrounding environment and vegetation through on-board sensors, such as cameras, lidar or infrared sensors. Through image processing and machine learning algorithms, it is able to identify and distinguish between weeds and plants.

– Navigation and positioning: Robots use built-in navigation systems, such as global positioning system (GPS), inertial navigation system (INS), or landmark recognition, to determine their own position and navigation path. This enables the robot to move precisely across lawns or fields, avoiding obstacles and reaching target areas.

– Weeding operations: Once the robot reaches the target area, it operates using different weeding methods. This could include lawn mowers, spraying herbicides, or mechanical weed killers, depending on the robot’s design and capabilities.

– Data recording and analysis: Some autonomous robotic weeders can also record and analyze data about the weeding process, such as the area weeded, the state of the lawn, and the density of weeds. This data can be used to monitor and optimize lawn or field management.



Despite the challenges, autonomous robotic weeders have great potential in agriculture and horticulture. As technology advances and continues to innovate, these robots are expected to become powerful tools for farmers and gardeners, increasing work efficiency, reducing labor costs, and enabling more sustainable weeding practices.


Crop Harvesting Robots

Crop harvesting robots are autonomous or semi-autonomous machines designed to perform the task of harvesting crops in agricultural fields. These robots use advanced technologies, such as computer vision, machine learning, and robotic arms, to identify and harvest ripe crops with precision and efficiency.

The working principle of crop harvesting robots typically involves the following steps:

– Crop Recognition: The robots are equipped with sensors and cameras that can analyze visual cues and spectral data to identify ripe crops. They utilize computer vision algorithms to detect characteristics such as color, size, and texture to determine the crop’s readiness for harvesting.

– Navigation and Localization: Harvesting robots utilize navigation systems like GPS, lidar, or laser sensors to determine their position in the field. They navigate through the crop rows using pre-programmed paths or real-time mapping techniques, avoiding obstacles and adjusting their movements for optimal harvesting.

– Crop Manipulation: Once a ripe crop is identified, the harvesting robot employs robotic arms or grippers to perform the harvesting task. These robotic appendages are designed to delicately grasp and detach the crop from the plant, mimicking the actions of human harvesters.

– Collection and Sorting: After harvesting, the robots often deposit the crops into designated containers or conveyors for further processing or sorting. Some advanced robots can even perform preliminary sorting based on size, quality, or other predetermined parameters.



However, there are some challenges and considerations associated with crop harvesting robots. These include the adaptability of robots to different crop types and field conditions, handling variability in crop growth and positioning, and the cost of implementing and maintaining robotic systems. Furthermore, certain crops with complex or delicate harvesting requirements may still require human intervention or specialized harvesting equipment.

Although agricultural robots are increasingly used in agriculture, it is unlikely that agricultural robots will completely replace humans in the foreseeable future. Only when artificial and agricultural robots cooperate with each other can they have the highest work efficiency.
