With the popularity of robots, robot threat theory has also begun to prevail. Will robots take away our jobs? We often ask this question. Some people think that this is worrying people, but some people think that you need to plan ahead. As everyone knows, although the robots have come under threat, it has also helped us to a large extent. What we have to do is treat them as friends rather than as enemies.
Recently, the Australian Wild Robot Center has developed a new type of four-wheeled robot called SwagBot. The purpose of the researchers to develop it is to allow it to help farmers monitor the overall health of livestock and crops.
It is reported that SwagBot can help farmers grazing, harvesting crops and towing trailers. In addition, it has the flexibility to bypass the ditch, cross the stakes, pass through the marshland, and move freely on the rugged mountain roads.
According to Salah, a professor of robotics at the University of Sydney, SwagBot will be able to measure the temperature of animals and plants over long distances, analyze the activities of animals and ensure their safety at night. He said: "We hope SwagBot will monitor the farm 24 hours a day to ensure the health of livestock and crops."
On June 30, the first field test of SwagBot was successful. If put into practice, it will become the world's first farm robot capable of monitoring the health of livestock.
In fact, this is not the first time that robots have benefited agriculture. It can be said that with the mechanization of agriculture, more and more high-tech has begun to be applied to agriculture, and robots are representatives of these high technologies. In fact, robots can not only detect livestock and crops, they can also milk and fertilize.
At the Cambridge Dairy Farm, milking is done entirely by robots without any manual work. The robot is installed next to the cow's hut. Once the cow needs milking, it will automatically wait in line for the robot service. At this time, the robot will first scan and locate the cow's breast, clean and disinfect it, fix it by automatic sensing, and then milk it. 
The role of robots is not only milking, but also milk quality testing during milking. Testing includes protein, fat, sugar content, temperature, color, electrolytes, etc., for milk that does not meet quality requirements, automatic transmission To waste milk storage; for qualified milk, the robot also has to discard each time a small portion of the milk is initially extruded to ensure quality and hygiene.
Milking robots also have the role of automatically collecting, recording, processing the status of dairy cows, the amount of milk produced, the frequency of milking each day, and transferring them to computer networks. In the event of an abnormality, it will automatically alarm, greatly improving the labor productivity and milk quality, effectively reducing the incidence of cow disease, saving management costs and improving economic efficiency. According to the survey, the use of milking robots can increase milk production by 20% to 50%.
At the same time, researchers at an agricultural machinery company in Minnesota, USA, introduced a robotic robot Rosphere. It will start from the actual conditions of different soils and fertilize properly. Its accurate calculation rationally reduces the total amount of fertilization and reduces the cost of agriculture. Due to the science of fertilization, groundwater quality has improved.
The appearance of the robot is like a rubber sleeve, and the mechanical part is constantly moving the center of gravity, because it uses a pendulum, an axis plus something that can be rotated, so that the ball can guide itself. The pendulum can swing freely in the horizontal or vertical direction, so controlling the pendulum can control the robot to roll forward or backward. In addition, the robot has a WiFi antenna for remote control.
Rosphere will mainly be used in precision agriculture in the future, instead of spraying pesticides on planes and fertilizing large areas. This small robot will tend to be a gardener. It can move crops without damaging crops and use insecticides and fertilizers precisely under certain conditions. At the time of testing, the small robots passed different rugged terrain and different soil moisture tests, and achieved very good cooperation with humans. So far, the test results have been quite satisfactory.
Seeing here, many people will ask: Then, will the peasants be robbed of their jobs by robots? At least for now, there is no need to worry about the scope of application of robots is still relatively narrow. In addition, even if the robot introduces large-scale agricultural planting areas, new jobs will be born at the time: robot operators, robot monitors, and so on. Therefore, what we have to do is to keep learning and make progress so that we will not be eliminated by robots.
The MTP series DC Power Supplies are High Power DC power supplies developed by iDealTek-Electronics based on IGBT semiconductor components, adopting AC/DC power processing topology with full-bridge phase-shift soft-switching technology. This series of High-power DC power supplies have the most output models and the widest output range in the company's DC power supply series, from 3KW ~ 30KW integrated in 19-inch standard rack-mounted high-precision DC power supplies to 45KW ~ 2000KW with casters or floor-standing Cabinet type High Power DC power supplies, output voltage up to 2000VDC, output current up to 6000A.
This series of High-power AC - DC power supplies are equipped with a reliable two-stage conversion mechanism drive logic circuit and a fast control loop optimized by iDealTek-Electronics. Which balances the requirements of low output ripple and fast DC output response speed, making this series of High-power switching power supplies can provide high-precision, low ripple, high-stability and High-power DC output with fast response speed feature of the switching power supply. All MTP series DC power supplies are equipped with a short-term 2 times rated current overload capacity (Except for some high-current output models) to cope with the inductive and mixed load's demand for high-current output at the moment of starting.
The full range of MTP series high-power DC power supply adopts digital control circuit. You can set and control the power output through the buttons on the front panel of the power supply (3KW ~ 30KW) or LCD touch screen (45KW ~ 2000KW). The high-precision 4 1/2-digit LED (3KW ~ 30KW) or LCD (45KW ~ 2000KW) provides intuitive, high-precision output display and measurement functions. At the same time, the full range of MTP high-power DC power supplies are equipped with RS485 interfaces as standard, following the MODBUS-RTU international communication protocol, which can realize remote control and operating status monitoring of the power supplies.
At present, this series of High Power DC power supplies are mainly used in Battery charging testing, DC motor testing, Photovoltaic inverter testing, and various cutting-edge applications that require High-power DC output.
