A smart farming startup has launched the third element in its robot system for pesdticide-free agriculture, an AI-based system called WIlma
Wilma, developed by the Small Robot Company, provides ‘per plant intelligence’, using precise information gleaned by Tom, a scouting robot, on the health of the plant. If Wilma identifies the plant as a weed then Dick – the world’s first non-chemical robotic weeder – is dispatched to zap it.
The smart farming agri-robots are being trialled on three farms. “The first commercial version of Wilma creates a per-plant crop map and is then AI-enabled to recognise disease and the nutrient status of the plant, enabling precision weeding by the farmbots and, in the future, application of water, nutrients or fungicide as appropriate – cutting chemical use and emissions," said Ben Scott-Robinson, CEO and co-founder of Small Robot Company.
“Wilma can direct Dick on the most effective course across the field. The robot then kills the weeds, such as blackgrass, using the Rootwave technology, which is electric so there is no problem with resistance,” he said.
“In a post-glyphosate world the ability to quickly kill pernicious weeds as they appear means that farmers don’t need to wait to drill and can take the opportunity to get crops started in the better weather in early autumn. Our lightweight farmbot Harry will also be equipped to precision drill without damaging the soil.” The weed zapping and slug control are two initial applications for the farmbots and these applications are attracting attention in Latin America. Slugs are a growing problem as new varieties of slug have invaded and the traditional slug pellets which contain metaldehyde or Iron (Ferric) phosphate are being withdrawn.
Tom can also detect slugs using hyperspectral imagery and artificial intelligence. It is intended that detection and mapping of slug infestations will be happening in-field in summer 2021, with Dick adding precision spraying as part of his ‘crop care
