A trio of tech companies have joined forces to develop what they claim is the world’s first driverless spot sprayer.

The autonomous Australian outfit features a custom-built 2,500-litre Prairie Special trailed sprayer kitted out with Bilberry’s green-on-green weed detection system.

It includes six cameras mounted at 3m intervals on the 18m boom, and a Raven controller.

Completing the package is Swarm Farm’s artic-steer Uniform driverless tractor, which runs a Hatz four-cylinder diesel engine rated to 83hp and a hydrostatic transmission with a top speed of 10kph.

The vehicles are manufactured at the firm’s base in Emerald, Queensland.
