Ranger vs. Ranger Mini 3.0 vs. Ranger Air
The AgileX Ranger series is a lineup of three omnidirectional four-wheel steering UGVs (unmanned ground vehicles) for research labs, universities, warehouses, and field robotics teams. Spanning payloads from 80 kg to 150 kg, the series covers everything from a compact indoor research base to a heavy-duty outdoor platform.
All three models, AgileX Ranger, Ranger Mini 3.0, and Ranger Air, steer on four wheels, so they can drive forward, rotate in place, and move sideways. This makes them easier to position in narrow aisles, around equipment, and next to workstations than a conventional two-axle or differential chassis.
What sets the models apart is payload, ground clearance, and ingress protection. The Ranger Air is the smallest and lightest, the Ranger Mini 3.0 adds payload, clearance, and weather protection, and the Ranger carries the most weight over the roughest ground. The sections below explain what each difference means in practice.

AgileX Ranger Air in Detail
The Ranger Air measures 552 × 500 × 250 mm and weighs about 53 kg, which makes it the easiest of the three to move, store, and use indoors. It carries up to 80 kg on a 24 V 30 Ah lithium iron phosphate battery and runs up to 6.5 hours without load or 2.5 hours at full load. Four 150 W drive motors and four 50 W steering motors give it four-wheel steering with Ackermann, self-rotation, oblique, and lateral movement modes.
For development, it provides a CAN 2.0B interface at 500 kbps, a ROS package, and aviation connectors with up to 25 A and 600 W of power for sensors and other equipment. It has no built-in obstacle avoidance sensors, so for autonomous work, researchers need to add their own sensor payloads.
For labs, warehouses, and mobile manipulation on flat surfaces with payloads up to 80 kg, the Ranger Air is a good fit. If you need to cross uneven ground, climb steeper slopes, work in wet conditions, or carry heavier payloads, consider the Ranger Mini 3.0 or the Ranger.
AgileX Ranger Mini 3.0 in Detail
The Ranger Mini 3.0 measures 720 × 500 × 345 mm and weighs 73 kg. Compared with the Ranger Air, it carries 40 kg more (up to 120 kg), has almost three times the ground clearance (105 mm), crosses obstacles up to 75 mm, and climbs 20° slopes. Its IP54 rating makes it the first model in the series suited to dust and splashing water. AgileX positions it for broader field and delivery use.
For mixed indoor and outdoor research where the Ranger Air lacks the clearance or weather protection you need, and the Ranger is more platform than you need, the Ranger Mini 3.0 is the better base platform.
AgileX Ranger in Detail
The Ranger is the heavy-duty model, measuring 1228 × 876 × 520 mm and weighing 100 kg. It carries up to 150 kg, with 160 mm of ground clearance, 100 mm obstacle clearance, 20° climbing at full load, IP55 protection, and a top speed of 2.6 m/s. AgileX describes it as an omnidirectional four-wheel drive platform with servo hub motors, four-wheel independent suspension, and a hot-swappable modular battery.
The Ranger is built for heavy payloads and the toughest outdoor conditions. According to InDro Robotics experience, for heavy manipulators with long reach (such as the Kinova Link 6), the Ranger is a better option as the Ranger's weight helps keep the platform stable and prevents tipping during operation. As the largest and heaviest option, however, researchers should confirm it fits their workspace.
How to Choose a Ranger Platform
-
Indoor lab, university, or warehouse work on flat floors: the Ranger Air.
-
A mobile base for a robotic arm or embodied AI research: the Ranger Air or the Ranger Mini 3.0.
-
Mixed indoor and outdoor routes, light rain or dust, or slopes up to 20°: the Ranger Mini 3.0.
-
Heavy loads up to 150 kg, rough ground, wet outdoor conditions or as a mobile base for larger robotic arms: the Ranger.
