While many wheeled robots can navigate rough terrain, they often struggle to maintain a level body, limiting their functionality. The KATR, short for Kubota All-Terrain Robot, solves this issue by using extendable legs to keep its cargo deck even.
Developed by Japan’s Kubota Tractor Corporation, the KATR recently won a CES Innovation Award for its design tailored to agriculture and construction tasks.
On flat surfaces, the KATR moves on its four inner wheels. However, when faced with slopes or rough terrain, it lifts itself onto its four outer wheels, each attached to a hydraulic leg. These legs automatically adjust to keep the cargo deck level using onboard sensors and a specialized algorithm.
Additionally, each wheel is powered by its own electric motor, enhancing the robot’s off-road capabilities. Depending on the application and location, the KATR can be powered by either a battery pack or a gasoline engine.

The KATR can carry up to 284 lb (129 kg) and can be equipped with various tools and sensors for tasks like transportation, data collection, maintenance, and agricultural work.
Kubota plans to lease the KATR in Japan next year at a service cost target of 1,980 yen (about US$13) per hour, with potential expansion into the North American market.
