● Four-wheel-steer robot chassis
LUCHS A
BUILT FOR ROBOTS.
STEERS EVERY WHEEL.
Chassis by RJ Tech Limited / Autonomy by TerraAgent Robotics (TAR)


A compact, open mobile base for robots that need to get around.
Luchs A gives your robot a reliable pair of legs. It carries up to 100 kg, steers all four wheels, and talks to your computer over standard industrial interfaces. Mount your sensors and payload on the top rails, plug into the expansion bay, and start building the application instead of the drivetrain.
Four drive configurations, one platform. Skid-steer, front Ackermann, dual Ackermann or full four-wheel steering. The main body is shared; only the drive module changes. The line-up above shows all four builds.
Open by design. CAN, RS-485 and RS-232 control, a published protocol, and ROS 2 software with an SDK, robot model and simulator in the box.
Power for your payload. 48 V / 10 A and 12 V / 8 A outputs, each with over-current, short-circuit and over-temperature protection.
Safety you don't have to add later. Dual emergency stops, ultrasonic collision stop, power-on self-test and a monitored battery.
Two ways to buy. Take Luchs A as an open chassis for your own robot software, or with the TAR navigation kit and autonomy already on board. One platform, two starting points: you choose how much we deliver.
Advanced Features
Engineered for autonomy, indoors and out

Intelligent VCU
Speed, yaw-rate and steering commands over CAN 1 Mbit/s or RS-485 / RS-232, with odometry-grade feedback. ROS 2 and ROS 1 drivers and a C++ SDK.

Independent Suspension
Double wishbone front and rear on the A-DF, A-FA and A-DA builds; independent swing arms on the four-wheel-steer A-4WS.

Distributed Electric Drive
Four 250 W servo hub motors, one per wheel. On the A-4WS, four 140 W steering servos turn every wheel.

Strong Lightweight Structure
Carbon steel and aluminium alloy frame. 65 kg chassis on an 800 × 580 mm footprint, carrying up to 100 kg.

Energy Management System
48 V 30 Ah LiFePO4 battery with BMS: up to 12 h unloaded on one charge. Drive is disabled while the charger is connected.

Payload Rails and Power
Two 2040 aluminium rails, 700 mm long at 200 mm centres, plus 48 V / 10 A and 12 V / 8 A outputs for your sensors and computer.

Configuration Packages
The preconfigured sensor packages offer everything needed to get started quickly. Additional hardware can be added or substituted upon request. Prefer to integrate your own sensors? Luchs A is also supplied as a bare chassis, with the published CAN protocol, SDK and simulator.

Indoor Navigation
Drive it around once to build a 3D LiDAR map, then pick any point on the map as a goal. It re-plans around new obstacles.
City Streets
Gives way to people, passes bollards, waits for traffic and red lights, and crosses at zebra crossings.
Campuses and Plazas
RTK GNSS keeps the position accurate on open ground. It drives to its goal and parks among the scooters.

Fixed-axle bases need room to turn; Luchs A does not. All four wheels steer: it crabs sideways, pivots on the spot and carries your payload, with CAN, RS-485, RS-232 and 48 V / 12 V power ready. Available as an open chassis, or with TAR autonomy on board.
