This robot can pick tomatoes without bruising them and detect ripeness better than humans

This robot can pick tomatoes without bruising them and detect ripeness better than humans This robot can pick tomatoes without bruising them and detect ripeness better than humans . The Virgo is a self-driving robot with sensors and cameras that serve as its eyes. Because it also has lights on board, it can navigate large commercial greenhouses any hour of the day or night, detecting which tomatoes are ripe enough to harvest. A "system-on-module" runs the Virgo's AI-software brain. A robotic arm, with a dexterous hand attached, moves gently enough to work alongside people, and can independently pick tomatoes without tearing down vines.

But can robots take over the job? An engineer working for Nissan has built a prototype robot duck and is testing it in rice fields in Japan .

Farmers use ducks to help keep the water in their paddies fresh, and to get rid of weeds and other pests that could damage their crops. Duck manure also works as a good organic fertiliser, which helps to decrease the amount of money farmers spend on harmful pesticides.

For centuries, rice farmers in Asia have used ducks as a natural alternative to pesticides. While paddling around in flooded paddy fields, ducks tear up weeds and snack on insects, with their manure even acting as additional fertilizer. In the 21st century, this practice is not widespread, but a new technological twist on the method could change that.

An engineer working for Japanese carmaker Nissan has built a robot alternative to paddy field ducks. As reported by Nippon.com and Nerdist, he’s currently testing his prototype in the Yamagata Prefecture in northeastern Japan. It seems it’s just a DIY project at the moment, with no plans for commercialization or even any data on how effective it is, but it’s a fascinating use of technology all the same.

The results showed that under rice - duck farming , the weed density in paddy fields decreased significantly, and the control effects on dominant weed species such as Monochoria vaginalis, Cyperus difformis, Sagittaria pygmaea were all above 95%, with an overall effect higher than CW and MW.

The Aigamo robot is named after the breed of duck used in the modern version of this ancient practice. (You can read more about how rice and duck farming has evolved in modern Japan here.) The robot weighs 1.5 kilograms and is about the size of a large robot vacuum cleaner. Two rotating rubber brushes on its underside take the place of a duck’s feet, which oxygenate the water by stirring it up and preventing weeds from taking root.

You can watch a video of the robot in action above. Unfortunately, there are no English subtitles to fully explain what we’re seeing. Still, it’s an adorable robot that manages to blend old and new agricultural techniques. In Japan, where rice farming is threatened by declining consumption and an aging population, it could help a culturally important industry survive in the 21st century.
