Australian manufacturer and agricultural equipment supplier Calibre Spraying recently introduced its Swarm Series autonomous sprayers. These sprayers are equipped with advanced technology and designed to harness the power of AI to deliver precision weed control applications.
The sprayers, a collaboration of Calibre Spraying, SwarmFarm Robotics and WEED-IT capabilities, use fluorescence technology day or night to detect and target green organic matter.
“We identified what SwarmFarm was doing, and it aligned with our philosophy,” says Calibre Spraying Director Daniel Watkins. “We wanted to build a sprayer from the ground up that was 100% for autonomous spraying.”
The 18, 24 or 27 m (60 to 90 ft.) wide boom units come standard with a 3,000-liter (800 gal.) main tank and a 400-liter (105 gal.) flush tank. It’s powered by WEED-IT and includes spot, dual, and blanket spraying options with Pulse Width Modulation (PWM). The PWM feature rapidly pulses each nozzle on and off, changing the duty cycle while holding a steady pressure. This results in consistent droplet size for better coverage and weed control at any speed. Booms are lightweight, with one sensor per meter, offering more sections with individual nozzle control for reduced overlapping and greater savings.
Additional features include a control panel, hitch suspension for a smoother ride, automatic height controls, high clearance suspension, wheel speed sensors for added precision, and a hand wash and electric flush cycle.
“In the future, the biggest advantage will be using 100% of the spraying window while sticking to the exact chemical label requirements,” says Tom Holcombe, Field Operations Lead at SwarmFarm. “We’re not restricted. SwarmFarm’s integration with Calibre Spraying is exciting as we’re pushing the boundaries of technological limits, plus running in the crop with a capacity of up to 3,000 liters (800 gal.) at 1.4 m (4.6 ft.) crop clearance.”
The autonomous sprayers are manufactured in Brookton, Western Australia.
