Kepler Robotics Unveils K2 "Bumblebee" at IROS 2025, Building a Global Developer Ecosystem Through an Open Robotics Platform

HANGZHOU, China, Oct. 27, 2025 /PRNewswire/ -- The 2025 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2025), one of the world's leading robotics events, was held in Hangzhou from October 19 to 25, 2025. The conference drew more than 7,000 leading experts, researchers, and industry professionals from around the world. 

Shanghai Kepler Robot Co., Ltd. ("Kepler Robotics") introduced its humanoid robot K2 "Bumblebee" at the event, showcasing the company's latest advances in humanoid robotics technology and open developer ecosystem initiatives. The presentation highlighted the growing global presence of Chinese humanoid robotics. 

Demonstrating Technological Capabilities of Chinese Humanoid Robotics on the World Stage

IROS ranks among the largest and most influential academic conferences in robotics worldwide, with this year's event being the biggest to date. Under the theme "Human-Robotics Frontier," IROS 2025 brought together leading robotics firms from around the world for a wide-ranging exhibition of emerging technologies and next-generation products.

At the Kepler Robotics's booth, the K2 "Bumblebee" walked with fluid, humanlike motion. When engaging with visitors, it responded naturally with gestures such as thumbs-up and wave. During the conference's robot parade, the K2 "Bumblebee" performed with poise while walking and completing its routine. Its superior mobility, precise manipulation, and natural interaction drew consistent praise from attendees.

The impressive performance of the K2 "Bumblebee" stems in part from its hybrid actuation system, which integrates roller screw linear actuators. The Kepler Robotics engineering team developed a custom architecture that combines roller screw linear and rotary actuators, enabling a natural straight-knee walking gait. Its proprietary planetary roller screw actuator delivers high torque density, precision control, and sustained durability. Working in tandem with rotary motors, it drives joint movement while maintaining motion accuracy. 

In addition, the K2 "Bumblebee" successfully addresses the Sim-to-Real transfer challenge. Using reinforcement learning and GPU-accelerated physics simulation, thousands of robot models with varying parameters can be trained simultaneously across diverse scenarios to systematically refine locomotion control. Through imitation learning, a high-fidelity physics simulator enables the robot to replicate human walking behaviors with remarkable efficiency, condensing years of training data into hours. Reward-driven algorithms guide the robot to mimic human motion while optimizing for speed, energy efficiency, and balance. On site, Kepler Robotics showcased its Isaac Gym platform for large-scale parallel training and reinforcement learning, alongside the MuJoCo platform for physics-based simulation and feedback.

Kepler Robotics Launches One-Stop Developer Platform to Accelerate the Humanoid Ecosystem

As humanoid robots emerge as a key area for technological innovation, industry discussion increasingly centers on how to build and grow a sustainable ecosystem. Kepler Robotics emphasizes that progress in the field depends on open collaboration and knowledge exchange with the global developer community. 

At the conference, Kepler Robotics introduced its developer platform, featuring tools for custom application development, including robotic arm control interfaces, motor APIs, and modules for vision, navigation, and voice. The platform is designed to support developers worldwide through four key components: Full-Stack Openness, an Integrated Perception-Decision-Control Toolbox, High-Fidelity Simulation & Digital Twin, and Modular Scene-Building Capability.

As part of its full-stack openness approach, Kepler Robotics has opened access to the core of its microkernel-based Nebula OS to developers and standardized software and hardware interfaces.

For system integration, the platform includes a built-in multimodal interaction engine that combines visual, auditory, and tactile data, giving developers out-of-the-box capabilities for perception and response.

In ultra-realistic simulation and digital twin applications, the Kepler Robotics Developer Platform delivers a physics-accurate virtual testing environment that enables "zero-risk" prototyping and "zero-cost" iteration. Code validated in simulation can be deployed to physical robots with one click, accelerating the path from concept to deployment. 

For scene composition, within Kepler Studio, developers can assemble motion primitives using graphical drag-and-drop tools and natural language input, enabling rapid creation of complex task sequences and simplifying robot programming. A dedicated skill marketplace with shared resources will also be available to developers in future updates. 

The Kepler Developer Platform directly addresses key developer considerations such as accessibility, security, and cost. It provides a full-spectrum toolchain—from intuitive visual interfaces to code-level control— to support developers at every skill level. Multi-layered security frameworks help ensure safe and reliable operation throughout development and deployment. By combining efficient simulation with modular design, the platform reduces wear on hardware and shortens debugging cycles, allowing developers to focus more on innovation and real-world application. 

To further drive ecosystem development, Kepler Robotics launched the Lighthouse Program, partnering with leading developers and industry collaborators to co-create solutions and accelerate commercialization. The initiative provides technical resources, market channels, and funding opportunities to help bring breakthrough concepts to market.

The IROS 2025 conference has drawn global robotics attention to China. Through its participation, Kepler Robotics gained fresh technical insights into potential industrial applications. More importantly, by bridging academia and industry, the company renewed its call for global developers to join its open ecosystem, reaffirming its commitment to driving innovation in humanoid robotics and expanding its real-world adoption.

Kepler Robotics Unveils K2 "Bumblebee" at IROS 2025, Building a Global Developer Ecosystem Through an Open Robotics Platform

SHANGHAI, April 5, 2026 /PRNewswire/ -- The 93rd China International Medical Equipment Fair (CMEF) will be held from April 9 to 12 at the National Exhibition and Convention Center (NECC) in Shanghai. As the largest global medical device industry chain exhibition, this year's event under the theme of "Innovation Fusion, Boundless Evolution," will focus on cutting-edge technologies and international trade cooperation.

Covering a total area of over 320,000 square meters, it will bring together nearly 5,000 brands and companies from more than 20 countries and regions and is expected to attract over 200,000 professional visitors and buyers from 150 countries and regions.

This year's CMEF highlights the rapid rise of AI, with a new lineup of "AI + healthcare" products reshaping the industry. Making its global debut, an AI agent capable of "one scan, multiple diagnoses" enables simultaneous detection of conditions across different parts of the body. A specialized AI diagnostic software suite is already in clinical use, while an integrated AI training and inference platform will enhance computing capabilities for healthcare institutions.

With advances in medical robotics, the exhibition will showcase new products across surgery, rehabilitation, and elderly care, driving the field toward greater intelligence and precision.
