Orca I is Cyan Robotics' full-size humanoid and the more capable of its two characters, standing 1.51 m and weighing about 42 kg with 28 degrees of freedom. Its headline claim is that it is the world's first straight-knee walking full-size humanoid: rather than the bent-knee crouch most humanoids adopt, it walks with straight knees, which the company says handles slopes and impacts while consuming less energy and lasting longer, and which it pairs with an emotional gait model that lets each step carry mood. It is also claimed as the first humanoid designed specifically for real-world reinforcement learning deployment, with an emotional gait foundation model that lets the robot learn and select its own gaits. Manipulation is a breakthrough end-to-end dual-arm model with no explicit visual rule injection, reported at above 95 per cent success for short-horizon tasks and above 90 per cent for medium and long-horizon tasks, with about 5 kg per arm and 10 kg across both, and a dexterous hand as the end effector with an adaptive soft gripper supplied alongside. The body is 1510 by 520 by 280 mm standing, with 0.66 m of arm span, 0.84 m legs, 150 Nm of knee torque and dual encoders on the joints. It perceives through 3D LiDAR, a depth camera and an IMU, hears through a six-element circular microphone array, and connects over Wi-Fi 6 and Bluetooth 5.2. Compute is a 14-core CPU with an NVIDIA Jetson Orin Nano Super module. Two quick-release 5000 mAh batteries give 2 hours standing and 1 hour walking. A smart emotional display screen shows mood in real time, and a large language model drives emotional body language for interaction. For developers it opens the full interface with a small Sim2Real gap, 500 to 1000 Hz bottom-layer communication, standard example code plus advanced motion training and deployment code, and an open whole-body teleoperation interface. It won an Asia Design Gold Award.
