ShanghaiJune 18, 2026 /PRNewswire/ — Recently, Kepler Robot officially announced the release of the Kepler Long-Endurance Heavy-Duty Quadruped Robot “Mechanical Qilin” series. As a “practical performer” professionally designed for industrial heavy-load scenarios, Kepler Robot has fully deployed its core black technology honed over years. Unlike ordinary “electronic pets,” the Kepler Mechanical Qilin series can perfectly achieve “truly load-bearing, truly running, and truly durable.”
Quadrupeds Should Not Be Just “Electronic Pets”
Currently, mainstream quadruped robots on the market primarily focus on agile movement capabilities and light-load inspection functions, forming mature applications in scenarios such as consumer displays and routine inspections. However, in heavy-load industrial transport, mountain special supply, and other high-load operation scenarios, there remains a performance gap in the industry that needs to be filled.
The original intention behind developing the Mechanical Qilin series is to break away from homogenized skill competitions and focus on heavy-load scenarios that others struggle to handle. From core components to overall machine design, the entire process is centered around the three industrial necessities of heavy load, durability, and long endurance, creating a productivity tool that can truly replace manual labor for heavy lifting.
Shared Core Technology with K2 Bumblebee Industry’s Only Full Product Line with Screw Solution
The previously released humanoid robot K2 Bumblebee, relying on this fully self-developed planetary roller screw actuator, easily achieved a dual-arm load of 30 kg, 1 hour of charging for 8 hours of continuous work, achieving industry-leading load capacity and long-term operational performance.
The Mechanical Qilin series fully inherits this flagship-level power core. From the humanoid robot K2 Bumblebee to the Mechanical Qilin series, Kepler is the only company in the industry to equip its entire product line with self-developed planetary roller screws. This is not a temporary adaptation solution but a core technological asset that has been validated across multiple product categories and iteratively refined.
Compared to the industry’s mainstream traditional servo joint solutions, the planetary roller screw structure has inherent advantages, naturally possessing a “strongman physique”:
- Higher structural rigidity: Under heavy-load conditions, the machine body shows no significant shaking or deformation, greatly improving durability;
- Lower transmission loss: Energy utilization efficiency is significantly optimized, fundamentally solving the industry pain point of “heavy load and endurance cannot coexist.”
Compared to the commonly used hydraulic drive solutions for heavy-load quadrupeds, the comprehensive advantages of this planetary roller screw electric route are more practical. Hydraulic drive works like a hydraulic jack, with a high static load limit but inherent shortcomings; the planetary roller screw solution achieves near-hydraulic-level heavy-load capacity while fully avoiding these pain points.
- Pure electric structure: No risk of leakage pollution, no need for oil circuit maintenance, lower long-term use costs;
- Higher transmission efficiency and more energy-saving: Better endurance performance under the same battery capacity;
- Stable operation in both high and low-temperature environments: Wider adaptability to various scenarios;
- Higher motion control precision: Enables precise docking with production lines, better suited for routine and refined factory operations.
Greater strength in the same volume; longer runtime under the same load. This fundamentally solves the industry’s long-standing problem of “heavy load inevitably means high power consumption and poor endurance.”
Near-Ton-Class Giant, Hard Strength Proven by Real Tests
As a large-sized model specifically designed for heavy loads, the Mechanical Qilin series has a standing size of 2175mm × 800mm × 1630mm and weighs approximately 300kg, truly a “big guy with great strength.” Leveraging the inherent advantages of the screw architecture, the entire machine is rated for near-ton-class loads. How strong is it? Multiple real-world scenario tests verify product performance:
1. Standing on it is basic:
Multiple adult engineers stand on the machine body simultaneously; the body remains as stable as flat ground, with no joint sinking or body deformation, showcasing visible structural strength;
2. Smooth load transport in the factory:
Carrying full industrial materials while shuttling through the workshop, starting, stopping, turning, and crossing speed bumps at a constant speed without wobbling, handling daily transport tasks effortlessly;
3. Towing a vehicle with no pressure:
Pulling a full-size commercial vehicle smoothly forward; the power reserve is obvious without further explanation;
4. Direct docking with full pallet loads:
Securely receiving and smoothly transporting standard industrial trays and full pallet goods, seamlessly integrating with existing warehouse and production lines without additional modifications.
Big Guy Also Has Long Endurance: 1 Charge for 8 Hours of Continuous Operation
Many may wonder: With such a large size and heavy weight, surely the endurance is poor?
On the contrary, despite the 300kg-level self-weight of the large heavy-load machine, the Mechanical Qilin series still achieves 1 charge for 8 hours of continuous operation. This places it at the forefront of products in the same class. Achieving 8 hours of efficient operation with high self-weight and heavy load is rare in the quadruped industry.
This performance stems from the low-loss characteristics of the planetary roller screw. In ordinary solutions, energy consumption rises sharply under heavy-load conditions, but the efficient transmission structure effectively controls energy consumption growth, truly achieving no compromise on load or endurance. It supports continuous operation without frequent recharging.
More Than Just a Robot: A “Practical Partner” on the Frontline
Under the guidance of the 2026 Humanoid Robots and Embodied Intelligence Real-Scene Training Special Action jointly launched by the Ministry of Industry and Information Technology and the State-owned Assets Supervision and Administration Commission, real-world scenario refinement has become the core path for embodied intelligence to move from demonstration to implementation. From the humanoid robot development stage, Kepler was among the first domestic companies to deploy industrial real-scene training. Leveraging dedicated real-scene training spaces, it has built a complete closed loop of “real-scene training – data accumulation – product iteration.” The Mechanical Qilin series will continue this core strategy, persistently conducting routine deployment and validation in real industrial and special operation scenarios, continuously optimizing product performance and scenario adaptability through real-scene data, steadily advancing the product from “usable” to “easy to use.”
The Long-Endurance Heavy-Duty Quadruped Robot “Mechanical Qilin” series made its debut at the recently concluded Zhangjiang Conference, marking the first step for the Mechanical Qilin. From the humanoid robot K2 Bumblebee to the Mechanical Qilin series, Kepler has always believed that embodied intelligence should not remain confined to slides and exhibition booths but should enter real industrial scenarios to genuinely help people solve problems. The fully self-developed planetary roller screw is Kepler’s strongest confidence.
The Kepler Mechanical Qilin is never just an exhibit in a showroom but an operational piece of equipment on the production frontline:
- In factory workshops, it is a tireless porter, replacing manual labor for heavy lifting and reducing the risk of workplace injuries;
- On border mountain roads, it is a mobile supply station, climbing slopes and overcoming obstacles to deliver supplies, reducing the burden on frontline personnel;
- In emergency scenes, it is a transporter charging ahead, delivering equipment to high-risk areas to ensure rescue safety.
Going forward, the Mechanical Qilin series will gradually open up more real-world tests and application scenarios. We also welcome more industry partners to join us in fully realizing the practical value of heavy-load quadrupeds and achieving long-term development of embodied intelligence in industrial applications.
