In May 2025, we wrote an overview of TRON 1, blown away by the world’s first modular foot-end bipedal robot and its R&D platform capabilities. Just six months later, we got our first glimpse of its successor: TRON 2. And—no exaggeration—our jaws hit the floor. Here’s why.
TRON 2 shattered our mental models for robot form factor. We watched, awestruck, as it transformed, seamlessly, from a “simple” two-legged biped, into a zippy wheeled machine (up to 5 m/s with 36 m/s² acceleration), then into a humanoid torso with absurdly strong arms. Official specs quote a 10 kg dual-arm payload, but seeing it lift a human tells you everything you need to know. And thing only get better - you can add an attachable head, teleoperate it, and even pair it with another TRON 2 to turn it into a full-size humanoid or a quadruped!
At this point, calling it a “robot platform” feels inadequate. To us, TRON 2 sits squarely in the category sci-fi fans know as Transformers. It could easily pass as Optimus Prime’s undercover little nephew.
TRON 2: Both a Full Spectrum R&D Platform and a Multi-Functional Real-World Contender
TRON 2 represents a significant upgrade over TRON 1 in terms of hardware, R&D offering, and industrial application readiness. The key highlights to be aware of:
- Expanded locomotion algorithm development capabilities thanks to design that enables humanoid and quadruped conversions (with additional hardware kit)
- Brand new advanced manipulation capabilities thanks to the option to convert from bi-ped to dual-arm design with interchangeable end-effectors
- Both RL and all-in-one VLA research platform with added teleoperation capabilities, expanding the range of research and real-life application options
Let's take a closer look at each of these updates.
Locomotion
Just like its predecessor, TRON 2 is an outstanding machine for anyone working on locomotion algorithms or simply in need of a very mobile robot.
TRON 2 comes with interchangeable flat feet and wheels and can jump, roll, climb stairs and conquer pretty much any terrain. Moreover, the new hardware can also pair with another TRON 2 and convert into a full-size humanoid or quadruped. As a result, TRON 2 meaningfully expands the range of locomotion algorithms and research possible.
Compared to TRON 1, the new model comes with:
- More battery power, longer runtime and faster charging (2,800 W max / 9 Ah vs. TRON 1’s 1,000 W max / 4.5 Ah)
- Up to 3× greater payload capacity (30 kg on flat ground, 20 kg on stairs vs. ~10 kg for TRON 1) allowing for a broader range of real-life applications
- Improved sensors and connectivity for better operation and navigation
As a bonus, TRON 2 comes with built-in boundary protection, which offers an additional layer of safety and accidental damage protection for both man and machine.
Manipulation
TRON 1’s arm expansion kits allowed for entry into manipulation research. TRON 2 takes this to a whole new level.
By far the most impressive feature of TRON 2 is its ability to convert into a torso with dual-arm configuration. In that form, the robot supports a wide range of end-effectors, including not only the common 2-finger clippers and 3-finger clippers but also our personal favourite, BrainCo’s Revo 2 dexterous hands. This is a game-changer for R&D labs as it massively expands the type of research and the range of algorithms that can be developed with the same kit.
The TRON 2 EDU version also comes with head and wrist RGBD cameras, enabling full-field perception, and can be teleoperated with excellent speed (100ms latency) and precision. The latter, coupled with the new manipulation capabilities of the kit, makes TRON 2 a serious contender for industry innovators looking for an agile, capable and flexible platform that can be deployed quickly on a wide range of real-world tasks.
An All-in-One VLA Platform
TRON 1 is a powerful platform for reinforcement learning (RL). TRON 2 carries forward the RL platform capabilities of TRON 1 and adds a VLA (Vision-Language-Action) platform on top.
The new hardware can be paired with ACT and Pi 0.5 classic models, alongside access to 10,000+ open-source real-world datasets. As is the norm for LimX, TRON 2 ships with comprehensive, user-friendly tutorials, ready-made examples, and working demos that promise VLA mastery in as little as two hours. We’re very much looking forward to putting that promise to the test.
And just like with TRON 1, TRON 2 algorithms can graduate to its bigger sibling, OLI, enabling a smooth progression toward next-generation humanoid research.
Open Systems / Tech Compatibility
Just like its predecessor, TRON 2 is built to make R&D easy. The new model supports thousands of open-source datasets and developers get a fully open SDK with both high- and low-level access, allowing control over virtually every aspect of motion and operation.
Under the hood, TRON 2 runs on an 11th-gen Intel® Core™ i7-1165G7 (2.80 GHz), with 2 TB of storage, and supports Python and C++ development, both ROS and ROS 2, and all major simulators—such as NVIDIA Isaac Sim, MuJoCo, and Gazebo. The result is a platform that lets researchers prototype behaviours in simulation and deploy them to hardware with minimal rewriting, helping close the Sim-to-Real gap.
A Final Thought
In hindsight, we were right to feel uneasy watching TRON 1 take a beating at ICRA2025. When we introduced it at London’s first Humanoid Summit, we joked about treading lightly—worried that OLI might remember.
Turns out, we should have been more concerned about TRON 2’s martial arts skills instead.
Who Are LimX Dynamics (逐际动力)?
LimX Dynamics was founded in 2022 in Shenzhen by the veteran robotic researcher Professor Wei Zhang and a team of robotics heavy-hitters with deep expertise in bipedal locomotion, stability control, multimodal robot control, reinforcement learning, and embodied manipulation. Their reputation has grown quickly — thanks to consistent overperformance of TRON1 and OLI in real-world research and applications, particularly across dynamic motion and control.
Considered to be among the rising stars of China’s humanoid robotics scene, the company raised its Series A+ round in March 2025 (with backing from Alibaba, China Merchants VC, SAIC Capital, NIO Capital, Lenovo Capital, and VitalBridge) and secured further $200m in a B round in February 2026 with backing from a group of strategic investors, including JD.com, Zhongding Group, Shanghai Capital (part of SAIC), NIO capital, Stone Venture and Oriental Fortune Capital and others.
LimX first launched TRON 1, the world’s first 3-in-1 bipedal robot, in late 2024 — quickly becoming one of the most respected legged robots of 2025. Their first full-size humanoid, OLI, debuted at the World Robotics Conference 2025 in Beijing and is now available on the market globally. TRON 2 was launched globally in December 2025.
