Project BRUUT is an initiative started by Jan Jaap Verweij, a Dutch dairy farmer and lead contributor to the open-source projects Cowcatcher and CalvingCatcher, where computer vision is transforming dairy farming; building on experience in software and electronics, the project expands into robotics to develop a simple, autonomous field robot that addresses key agricultural challenges such as reducing chemical use, lowering fuel and machinery costs, tackling labor shortages, and improving sustainability through applications like spot spraying, mechanical weed control, soil health improvement, and support for physically demanding work.
The robot in Action
A simple, affordable, and highly customizable solution. Whether you are a dairy farmer, arable farmer, or grow vegetables in greenhouses or in open fields, this tool carrier robot can be adapted to suit your needs and work seamlessly with 'community' or own machines.
