[China Agricultural Machinery Industry News] Artificial intelligence is the future development direction. According to a report released this week by the US government, the whole world is increasingly relying on artificial intelligence to automate. Without human supervision, machines can do more and more things. In the future, robots will replace these things manually. In less than 100 years, existing robots can do these 10 types of farm work!
Class: Robot milking
At the University of Cambridge Dairy Farm, the milking work is done entirely by robots without any manual work. The robot is installed next to the cow enclosure, and once the cow needs to be milked, it will automatically wait in line for the robot service. At this time, the robot will scan and position the cow's breasts first, clean and disinfect, fix the nipple by automatic sensing, and then milk.
The role of the robot is not only to milk, but also to test the milk during the milking process. The test includes protein, fat, sugar content, temperature, color, electrolyte, etc., and automatically transfer the milk that does not meet the quality requirements. To the waste milk storage; for qualified milk, the robot also discards a small portion of the milk that is initially extruded to ensure quality and hygiene.
The milking robot also has the function of automatically collecting, recording, processing the cow's physical condition, the amount of lactation, the frequency of daily milking, etc., and transmitting it to the computer network. Once an abnormality occurs, it will automatically alarm, greatly improving labor productivity and milk quality, effectively reducing the incidence of dairy cows, saving management costs and improving economic efficiency. According to the survey, the use of milking robots can increase milk production by 20% to 50%.
The second category: robot grazing
Australian inventors have created a robot like a shepherd that can replace traditional grazing labor (human or shepherd) on the farm. It uses 2D and 3D sensors and has a built-in GPS that keeps them moving according to the speed of the cows. The cattle are rushed around by the robot, and it’s interesting. At present, this robot is still in the testing stage, and the effect is ideal.
The third category: robot fertilization
Researchers from an agricultural machinery company in Minnesota, USA, have a unique robot that will start with proper fertilization from the actual conditions of different soils. Its accurate calculations reasonably reduce the total amount of fertilization and reduce the cost of agriculture. Due to the science of fertilization, the quality of groundwater is improved.
The fourth category: robot weeding
German agricultural experts have developed robots that can accurately apply herbicide weeding using computers, global positioning systems (GPS) and smart multi-purpose tractors. First, the agricultural workers led the robots to walk in the fields. When a plot with a lot of weeds is reached, the GPS receiver on it will display a coordinate map that determines the position of the weed. The agricultural workers first input the information into the portable computer on the spot, return to the field and then transfer the information and data to a computer on the tractor. When they drive the tractor into Tianwen Farming in the future, the weeding robot will closely monitor the position of the trip. If you come to the weed area, the corresponding part of its airborne rod sprayer is activated immediately, allowing the chemical herbicide to be sprayed accurately to the desired location.
The fifth category: robots care the vineyard
The French inventor invented the robot dedicated to the vineyard and named it Wall-Ye. It can almost replace all the work of plantation workers, including trimming vines, cutting out shoots, monitoring the health of the soil and vines. In addition, Wall-Ye has one more function than the existing plantation robots - the safety system. Wall-Ye can only work on planted farms that are programmed, and can also initiate self-destruction procedures in dangerous situations. In a dangerous situation, I would rather start the self-destruction process than "rebel".
The sixth category: robot seedlings
Most of the nursery work involves moving and transplanting potted crops, which is monotonous and boring, wasteful of manpower and inefficient. The nursery robot in Boston, USA, solved this problem well. This seedling robot consists of rolling tires, grippers and trays. As long as the staff sets the location parameters on the touch screen, the robot can sense the pots and automatically move them to their destination.
The seventh category: robot planting
German scientists have developed an agricultural robot called BoniRob, which is equipped with high-precision satellite navigation and can position itself within 2 cm. It is shaped like a four-wheeled off-road vehicle. It works by using a spectral imager to distinguish between green crops and brown soil. The position of each crop is recorded during the run, and they are returned to the field again and again during the growing season to observe their growth.
The eighth category: robot sorting fruit
In agricultural production, the classification of various fruits is an essential farm work, often requiring a large investment in labor. Researchers at the Silsor Agricultural Machinery Research Institute in the United Kingdom have developed a robust, easy-to-use fruit sorting robot that automates fruit sorting. It uses a photoelectric image recognition and lifting sorting mechanical combination device to work in a humid and muddy environment. It can distinguish between large tomatoes and small cherries, and then sort and ship them. It can also classify potatoes of different sizes. And will not scratch the skin of the fruit.
The ninth category: bee robot
Harvard engineers invented a small robot like a bee, which can pollinate like a bee, carry out post-disaster search and rescue work, and is a versatile robot. At the same time, there are British scientists who want to make better. They hope to invent a machine bee that simulates the real bee brain, allowing the robot to do all the work of the bee.
The tenth category: robot picking mushrooms
The UK is a country rich in mushrooms in the world, and mushroom farming has become the second-ranked horticultural crop. According to statistics, the annual mushroom harvesting amount is 110,000 tons, and the profit is very considerable. In order to improve the picking speed and gradually get rid of this heavy agricultural work, the Sylvester Institute of Agricultural Machinery in the UK developed a mushroom picking robot. It is equipped with a camera and visual image analysis software to identify the number of mushrooms picked and which grade they belong to in order to determine the operational procedures. After picking up the mushroom robot and measuring the height of the mushroom with the infrared rangefinder on the machine, the vacuum suction handle will automatically extend to the picking site, bend and twist as needed, and timely feed the picked mushrooms to the next. In the transport plane. It picks up 40 mushrooms per minute at twice the speed of the artificial.
