Slug-monitoring robot ‘game-changing’ hope

A three-phase programme to deliver a slug-monitoring robot is under way.

The project, led by Dr Jenna Ross from UK Agri-tech Innovation Centre Crop Health and Protection, aims to develop an innovative technology for autonomous slug monitoring and precision treatment of bio-molluscicides.

Current control methods rely on traditional chemical pellets, containing either metaldehyde or iron (ferric) phosphate.

The alternative, biomolluscicides are also available in the form of the nematode products, but are not economical for use in arable crops.

Dr Ross said she found a gap in the market for autonomous slug monitoring when travelling as a Nuffield Farming scholar, and described the project as “game-changing”.

Artificial intelligence input will be provided by Cosmonio, while the autonomous technology will be developed by the Small Robot Company.

Ben Scott-robinson, chief executive of Small Robot Company, said: “Both water and wildlife have been impacted by chemical methods, and legislation is looming – farmers need an affordable alternative.”

Phase one of the project will focus on developing the artificial intelligence slugdetection capability, including with multispectral imagery.

Phase two will look to deliver slug detection using Small Robot Company’s “Tom” robot, with mobile imaging of slugs and field-surface materials in glasshouse conditions anticipated by early next year.

The detection and mapping of slug infestations is anticipated to be delivered in field in spring 2021.

Phase three will then focus on development of precision spraying, delivering an in-field slug treatment solution for autumn next year.

Developers say the project has the potential to significantly increase yields through the enhanced monitoring and control of slugs.
