About the Lab

The Design & Reliability of Off-road Machinery Laboratory (DROM Lab) precisely designs machinery operated off the road — tractors, combines, and heavy construction equipment — and quantitatively verifies its performance, reliability, and service life. From gear & transmission dynamics and optimal design of positive-displacement pumps & flow meters to physics-informed AI sensorless fluid control, we connect distinct technologies into a single flow of research.

So that lab theory does not stop at a paper but reaches real products and the agricultural and industrial field, the accumulated core technology is commercialized through EVER Co., Ltd., a KNU Holdings subsidiary. Precision-spraying modules are proven by field delivery, and dispensers and compact flow meters by productization.
