The HKEX listed autonomous driving vendor's "Combo" hybrid system switches between rolling and walking for the final stretch. Pilot customers, deployment sites, and unit economics are still undisclosed.
On July 6, 2026, Minieye released a hybrid delivery robot that switches between four-wheel rolling on flat pavement and four-leg walking on stairs and curbs, built to handle the final stretch the company's autonomous vans cannot reach.
The system, announced as "Combo" by Shenzhen-based Minieye (佑驾创新, HKEX: 2431), pairs the new wheel-legged unit, made by affiliate Yaoxing Power (曜行动力), with the company's existing Xiaozhu-series unmanned logistics vehicles. A unified dispatch system routes parcels from mid- and long-distance road runs into the last tens of meters, where the wheel-legged unit takes over.
On flat pavement the robot rolls on four wheels at higher speed; on stairs, grass, curbs, or 45-degree slopes it shifts to a quadruped gait. Minieye's launch coverage puts continuous stair clearance at 30 centimeters, single-step clearance at 80 centimeters, maximum payload at 30 kilograms, and battery endurance at roughly two hours across an operating range of 0–55°C with a splash-resistant chassis. A small-radius turning mode targets tight residential courtyards; dynamic balance and anti-tip systems round out the package. That switching capability is what separates Combo from either wheeled sidewalk robots or legged quadrupeds alone.
Those numbers are vendor-supplied from the day-of launch report and the company's release copy, not independently benchmarked. Treat the spec sheet as a claim, not a measured result.
Combo is Minieye's first product that uses its L4 mapless autonomy stack to control both a road vehicle and a sidewalk robot. The company built its name on ADAS software and mapless L4 stacks; its first mapless L4 unmanned logistics vehicle was an autonomy milestone covered earlier in tier-1 Chinese tech media. With Combo, the same L4 stack now feeds both the road vehicle and the sidewalk robot. Perception, localization, and routing live in one software layer instead of two, which means every kilometer driven by a Xiaozhu van trains the dispatch system that hands off to the wheel-legged unit, and every doorstep delivery is a data point the road vehicle benefits from.
That reuse makes the launch a strategic statement, not just a product release. Minieye is now telling HKEX investors it wants to be a "physical AI" company rather than a supplier of ADAS modules, and the L4 stack is the asset it is monetizing twice. Listing on HKEX in December 2024 gave the company a public runway for that pivot; a follow-on HKEX announcement in August 2025 signaled continued product expansion beyond passenger-vehicle ADAS.
Chinese parcel volumes continued climbing through 2026 while courier hiring and retention costs keep squeezing the labor side of last-meter delivery. Wheeled sidewalk robots fail at stairs; legged robots are too slow for neighborhood-scale routes; open-road unmanned vans cannot reach the door. Minieye's launch copy argues that hybrid wheel-leg locomotion is what unblocks that gap, a framing echoed externally by JD.com founder Richard Liu's recent APEC remark that "robots will eventually replace couriers."
That framing is plausible but still vendor-side. The Combo release describes a "full-link unmanned closed-loop" solution but does not name pilot customers, deployment sites, fleet sizes, or per-parcel unit economics. Yaoxing Power is described as a "core-shareholder affiliate" in launch coverage; the exact ownership stake, founding date, and product roadmap stage (concept, demo, pre-order, shipping) should be sharpened against HKEX filings before the commercial picture is settled.
First customer disclosures and demo footage typically arrive within 72 hours of a Chinese launch; the Leiphone launch report is the primary anchor for now, with Minieye's own newsroom and HKEX filings as the secondary record.
What to watch: a named pilot site, a stated per-parcel cost comparison against human couriers, and a clearer Yaoxing Power relationship. Without those, Combo is a credible mechanism and a strategic signal, not yet a commercial fact.
