AgileX RANGER
AgileX Robotics · China · 2022
The full-size original of the RANGER line: 1.2 m long, 150 kg of payload, 2.6 m/s, and room for four batteries — eight motors, four of them purely for steering.
RANGER is the machine the smaller RANGER MINI was scaled down from, and it is a noticeably more serious piece of equipment: 1228 by 876 by 475 mm, 150 kg of rated payload, and a top speed of 2.6 m/s, which is the fastest of any load-carrying chassis AgileX sells. It carries eight motors — four 48 V brushless units driving the wheels and four more steering them, each wheel independently — which is what buys the three driving modes: Ackermann steering like a car, a spin on the spot, and an oblique mode in which the wheels turn up to 90 degrees and the whole vehicle crabs sideways without changing which way it faces. The electrical design is the part worth noticing. A single 48 V 24 Ah lithium iron phosphate battery charges in about an hour, and the vehicle takes up to four of them — which is how the maker gets from a two-hour runtime to an eight-hour one without a bigger charger. There is also a power take-off for whatever the buyer bolts on: up to 15 A at 46 to 50 V, alongside the CAN bus that carries all commands and telemetry. As with every AgileX chassis, nothing is fitted as standard above the deck — no sensors, no computer, no arm. A standard aluminium extension bracket is provided to mount them. Two things in the maker's own manual do not agree with each other, and a reader should know both. The document states in one place that an uncustomised RANGER is sealed to IP22 — barely more than drip-proof — and in another that it is waterproof and dustproof to IP55. It also gives a curb weight of 100 kg in the mechanical table and a weight of 135 kg with a single battery in the performance table. Neither pair is reconciled anywhere in the document. The gradeability figure is modest by comparison with the tracked machines in the range: 10 degrees. The manual's first draft is dated October 2022, which is the earliest firm evidence of the machine's existence; the vehicle has been listed in the maker's global store since April 2024 and is sold on enquiry rather than at a listed price.
