Shanghai / Zurich, 11 November 2026 — RJ Tech today announced the autonomous driving version of Luchs B, its off-road chassis for unmanned asset inspection vehicles. The autonomy stack is developed and supplied by TAR Robotics AG, based in Switzerland.

The problems it solves. Pipelines, energy sites and large rural assets stretch over long distances, often far from roads. Inspecting them by hand means long hours, heat, dust and travel for crews, and gaps between visits. Many sites have no charging infrastructure, the ground is rough, and access tracks are narrow. And operators do not want to keep paying for an expensive sensor package on every vehicle.

How Luchs B answers them: it patrols the same routes on its own, day after day, so crews only go out when something needs attention. The built-in range extender removes the need for chargers in the field. Dual Ackermann steering and 300 mm of ground clearance get it through tight tracks and rough ground. And the sensor set is designed to become lighter and cheaper over time.

Our approach: from full sensors to vision. The first Luchs B fleets drive with the full sensor set — LiDAR, cameras, radar and GNSS — so they are safe and reliable from day one. Every kilometre they drive also feeds a data pipeline: LiDAR and GNSS provide precise reference data that labels the camera images automatically, and a closed data loop retrains the vision models on real field data. As the vision models mature, the same routes can be driven with cameras and GNSS only: lower cost per vehicle, simpler maintenance, and models that keep improving with every patrol.

The video below walks through the data pipeline: how camera streams and measured LiDAR are combined into one scene, how models propose labels, and how reviewed labels become training datasets.

End-to-end autonomy. The driving stack runs end to end, from perception to control. Three sensor configurations are available: a mast with a 128-line LiDAR plus solid-state LiDARs and cameras; solid-state LiDARs and cameras without the mast; or cameras only. Every configuration covers 360°, with one radar at the front and one at the rear as a safety backup.

Built for rough ground. Luchs B drives on four in-wheel motors with dual Ackermann steering on the front and rear axles, dual electric power steering and an electric parking brake. It climbs 30° slopes, reaches 40 km/h and carries 125 kg in daily work (250 kg maximum), while keeping the quiet operation of an electric drive.

Where it works. Routine off-road patrols along oil and gas pipelines and energy sites, and inspection work in forests, grassland, farmland and desert.

Still an open platform. Customers who run their own autonomy can continue to use Luchs B as an open chassis over CAN and bring their own software.
