Greeting
“Making the machines that work off the road more precise, and longer-lasting.”
Our lab designs and validates off-road machinery — tractors, construction equipment, and farm implements — to work more precisely, longer, and more safely. By combining gear & transmission dynamics, positive-displacement pump & flow-meter technology, and physics-informed AI, we bring lab theory into real products and the agricultural and industrial field.
We warmly welcome students, researchers, and industry partners who want to see research realized as social value, not stop at a paper.
