Farmers invented a new way to use robots in weed control. The robot is used to behead weeds quickly. Some farms pick weeds manually to make sure that pesticides do not damage the crops. This robot will help to keep more crops along with making the farmer's job much more manageable.
The computer monitored robots currently work with soybean crops. The farmers are preparing for it to start working with sorghum, cotton, and possibly canola farms. They travel from 1 to 3 mph and are water-resistant, weighing about 200 pounds.
"Our mission was always to get the chemicals out of farming. There is no resistance to the spinning blade," says Clint Brauer, a Kansas farmer and founder of Greenfield Robotics.
The U.S.A is the world's largest user and producer of agricultural pesticides, utilizing 1.2 billion pounds of pesticides in 2016. Robots like these would lead to healthier and safer ways to control weeds.
Scientists are now using drones to help reduce the growing issue of plastic spreading across the ocean. People produce about 300 million tons of plastic every year, and at least 8 million of this ends up in our oceans. Utilizing drones to combat this problem can help save ocean life and reduce toxins in the environment.
The drones have cameras that map the location of plastic pollution through software and image recognition. The drones identify the type of plastic, size, and even the brand or source of the trash.
"Drones are a game changer for environmental monitoring. They allow us to survey an entire stretch of coastline in a few minutes. Ellipsis technology can automatically detect 47 categories of trash items with more than 95% accuracy," says Ellie Mackay, Ellipsis founder, and CEO.
Drones allow for a safe reach out into the ocean to collect data and clean up the sea for a better world.
A new submersible robot is preparing to explore the depths of the ocean without sonar technology. Usually, similar carriers are very heavy and cannot navigate their surroundings without the help of high-power equipment. This new autonomous model will save scientists in cost and increase the surface area they can uncover.
The robot called Orpheus has a vision-based navigation system similar to the one used in the famous Perseverance and Ingenuity devices that landed on Mars. It only weighs about 550 pounds and uses low-power cameras and lights along with advanced software to travel underwater.
“In the future, some of the most extreme ocean environments will be within our reach. From deep ocean trenches to hydrothermal vents, there are many new destinations we will explore,” said Andy Klesh, a systems engineer at JPL.
Scientists hope this new invention will help them answer important questions about life on other planets and discover new parts of the oceanic world.
