A robot even a cow could love

Farming is no stranger to automation, but many agriculture-related jobs demand a soft touch to handle delicate fresh foods, or require robots to work closely alongside humans and animals.

Collaborative robots (“cobots”) are making dramatic inrocollaborative-robots-in-the-farming-industry_362x483ads for those applications, giving agriculture and dairy operations the advantages of optimized production, increased competiveness, and the opportunity to free skilled labor for more appropriate tasks. And that all comes with the fastest payback time in the industry, making cobots ideal for agricultural operations.  

GNE Farm Equipment is using collaborative UR robots to reduce the labor costs of milking cows, which is helping the company address a decade-long shortage of qualified milkers. The cobot automates the labor-intensive process of manually disinfecting cows’ udders before and after being milked, and offers dramatic improvements over traditional robotic approaches.

A typical system requires a large robot with a camera and spray system. When triggered, the robot sends a six-foot-long pipe with the sprayer under the cow to apply the disinfectant. These floor-mounted robots require expensive installation into the milking parlor floor, as well as fencing to safeguard employees. The installation process interferes with dairy production for at least a month, and even after the robot is installed, it requires professional programming and training for all employees. Modular robotic systems are an option that can reduce installation complexity, but both floor-mounted and modular approaches take up valuable floor space that reduces the number of milking stalls available—which reduces output. And if the robot loses power while the pipe and sprayer are under the cow, the spray arm could injure the cow and damage the rotary milk stall and robot, resulting in costly repairs, reprogramming, and additional production downtime.

In contrast, the UR robot is moved in place on a small pallet jack, taking up no more space than a human milker. The system includes on-board storage for the robot computer, disinfectant storage tank, pumps, valves, and controls. It needs only a 120V hookup (not 240V or 480V as required for traditional large robots), so can be plugged into any available outlet. The UR robots need no safety caging—built-in safety features stop the robot’s movement if someone enters the working area. Similarly, if the robot loses power, the lightweight, flexible spray arm bends so it won’t injure the cow and is spring-loaded to return to the working position. The UR robot is easy for the dairyman to program using the touchscreen point-and-click application and simply moving the robot arm to the desired positions.

“No other robot on the market is currently able to offer this ease-of-use system,” says owner of GNE Farm Equipment, Gerard Niessink. “Since no specialists are needed for operation, the UR robots results in a faster payback. With the available bank lease programs there is no money out of pocket for the dairy man.”
