K2 Bumblebee by Kepler vs T800 by EngineAI

K2 Bumblebee employs a hybrid serial-parallel design with 52 degrees of freedom, 175 cm height, 75 kg weight, and proprietary planetary roller screw actuators for millimeter precision and 81.3% energy efficiency. T800 measures 185 x 60 x 40 cm, weighs 85 kg, and supports configurations up to high-end models with force sensors integrated for industrial durability. Both humanoid types prioritize stability, but K2 emphasizes in-house hardware for supply chain resilience while T800 focuses on scalable model variants.

K2 Bumblebee reaches 3 km/h with LiDAR, SLAM, and GPS for autonomous navigation, featuring disturbance-resistant gait and straight-knee walking for warehouse and factory floors. T800 attains 10 km/h using visual SLAM and LiDAR mapping, enabling faster movement in logistics and retail environments. K2 suits structured spaces with GPS integration, whereas T800 prioritizes speed for dynamic heavy-duty tasks.

K2 Bumblebee integrates over 80 sensors including 3D cameras, fisheye vision, tactile sensors up to 25 per finger, six-axis force-torque in wrists, IMUs, and ultrasonic sensors for fine manipulation. T800 uses RGB cameras, stereo cameras, LiDAR, ultrasonic sensors, IMU, gyroscope, force, and temperature sensors for comprehensive environmental perception. K2 provides advanced tactile feedback for precise handling, while T800 emphasizes stereo vision for depth in varied operations.

K2 Bumblebee supports AI autonomous control, natural language processing, and onboard computing up to 100 TOPS with Kepler OS, ROS compatibility, and APIs for vision and voice integration. T800 features autonomous operation, learned behaviors, and teleoperation using proprietary OS, ROS2, Python, and C++ for task execution. Both enable independent functioning, but K2 adds app control and NLP for guided tours, contrasting T800's focus on behavioral learning.

Both robots offer 4-year battery life, with K2 Bumblebee providing up to 8 hours per charge via high-efficiency hybrid actuators. T800 matches the extended lifespan without specified runtime per charge details. Shared longevity supports prolonged industrial shifts, with K2's efficiency validated at 81.3%.

K2 Bumblebee excels in warehouse automation, assembly assistance, hazardous operations, guided tours, and research with 30 kg payload capacity. T800 handles heavy-duty tasks, robot boxing, retail assistance, human interaction, and logistics. K2 targets precision manufacturing and R&D, while T800 fits high-speed, collaborative industrial roles.

K2 Bumblebee runs Linux-based Kepler OS, ROS compatible with APIs for integration and developer tools like simulation platforms. T800 utilizes proprietary OS alongside ROS2, Python, and C++ for custom programming. Both support open frameworks, enabling motion and perception customization.

K2 Bumblebee prices at $34,000-$40,000 for industrial-grade features including hybrid actuators and extensive sensors. T800 ranges from $25,000 base to $80,000 high-end, offering entry-level access with scalable upgrades. Base T800 undercuts K2, but high-end models exceed for advanced configurations.

K2 Bumblebee includes emergency stop, obstacle avoidance, disturbance-resistant gait, and force feedback for interaction. T800 provides force limiting, collision detection, emergency stop, and collaborative mode. Both ensure safe human proximity with layered protective measures.
