The 8-hour endurance benchmark was strategically selected to meet real-world industrial demands, balancing technical feasibility with operational requirements. Perfectly aligned with standard logistics and manufacturing shifts, the Forerunner K2's "1-hour charge, 8-hour endurance" capability enables seamless "9-to-5 plus overtime" workflow integration. This milestone represents the critical trifecta of commercial robotics: scenario adaptability, technological optimization, and economic practicality – ultimately delivering the optimal balance between reliable performance and cost-effective deployment for industrial applications.

Humanoid Workforce: K2 "Bumblebee" Demonstrates Industrial Versatility at WAIC 2025

At WAIC 2025, Kepler transformed the exhibition floor into four immersive demonstration zones replicating real-world environments: logistics sorting, material handling, automotive manufacturing, and education/research. Four K2 "Bumblebee" humanoids executed precision tasks in each setting, proving their viability as next-generation industrial workforce solutions.

Industrial applications demand both strength and stamina – challenges the K2 Bumblebee overcomes through its advanced roller screw actuator system. Capable of handling 30kg (66 lb) payloads with fluid, coordinated movements, these biomimetic actuators (strategically positioned in thighs, calves and arms) deliver superior load capacity and rigidity versus conventional ball screw systems. The inhouse multi-thread contact design – integrating lead screws, reducers and encoders – enables unmatched performance in high-speed, heavy-duty industrial operations.

Precision is another critical requirement for industrial automation, and Kepler's K2 "Bumblebee" delivers breakthrough performance. Song Hua, Vice President of Solutions at Kepler, demonstrated the robot's Nimble Master dexterity system – featuring six-axis force wrists, 11-DoF hands, and 25 force touchpoints per finger. Supported by an integrated rotary mechanism and AI algorithms, the K2 achieves 0.01-degree positioning accuracy and millimeter-level precision. Its human-like reflexive models enable instinctive adjustments – automatically modifying grip strategies when encountering sharp objects or slippery surfaces – ensuring reliable handling of irregularly positioned items.

The exhibition's highlight came as the K2 successfully sorted blind box gifts by color and labeling – a task challenging for conventional automation. While traditional systems struggle with soft, deformable packaging, the K2's purpose-designed micro-models provided real-time tactile and force feedback, enabling flawless execution. This demonstration proved the robot's superior capability in handling real-world logistics challenges that typically require human intervention.

The K2 "Bumblebee" achieves fluid motion through its revolutionary tri-component system: embodied perception, embodied decision-making, and embodied execution – mirroring the functional synergy between human brain and cerebellum. Kepler has strategically partnered with China's leading reasoning-based large language model providers to develop the system's advanced "brain" capabilities. Complementing this cognitive foundation, the K2's bionic architecture integrates multiple cameras and sensor arrays, empowered by Kepler's proprietary precision perception micro-models that enable real-time embodied decision-making.

Kepler's engineering breakthrough lies in its specialized micro-models, distilled from larger foundation models while preserving core functionality at dramatically reduced parametric complexity. These task-specific models undergo rigorous training to maximize operational success rates and stability. The K2 currently deploys multi-modal micro-models covering auditory, tactile, force and positional perception. During package handling operations, fingertip tactile sensors provide instantaneous feedback while dedicated force micro-models dynamically calculate perfect grip strength – ensuring secure manipulation of diverse objects.
