Q: Is Okulo C2 available for purchase now?
A: Okulo C2 is expected to begin sample delivery in early August 2026. For the latest mass-production schedule, final specifications, and pricing, please contact Point Spread’s sales team.
Q: What advantages does the dual-VCSEL architecture offer over a single-VCSEL solution?
A: Okulo C2 uses vertically arranged dual VCSEL emitters with synchronized triggering and combined illumination energy. Compared with a single-transmitter solution, it provides a higher signal-to-noise ratio, helping increase effective range under strong outdoor sunlight and improve point-cloud fill rates for low-reflectivity targets such as black or reflective objects. The two emitters also provide redundancy: if one fails, the camera can continue operating at reduced power instead of returning a blank depth image.
Q: How compact is Okulo C2, and where can it be installed on a robot?
A: The overall dimensions are 45 × 26.7 × 28 mm. Its compact form makes it easy to integrate into space-constrained locations such as the wrist or head of a humanoid robot, or the front, rear, and underside of a quadruped robot.
Q: Which interfaces does Okulo C2 support?
A: It provides dual USB 3.x and GMSL2 interfaces. USB supports direct local connection for development and debugging, while GMSL2 provides long-distance, interference-resistant video transmission for long-cable applications such as connections between a robot’s torso and end effector.
Q: What is Okulo C2’s latency performance?
A: Okulo C2 supports a 60 FPS high-frame-rate depth stream. Combined with Global Shutter RGB and Hardware-level Timestamp Synchronization (D2C+IMU Sync), it is designed to provide low-latency data for high-speed dynamic tasks such as legged locomotion and rapid robotic-arm grasping. Specific end-to-end latency specifications will be provided in the formal mass-production datasheet.
Q: Can Okulo C2 operate under strong outdoor sunlight?
A: This is a key validation item during development. The design uses higher-power Dual-VCSEL Synchronized Flood Illumination, a 940 nm narrow-band filter, and multi-frequency HDR to improve effective ranging under strong sunlight. Specific outdoor-usability specifications are subject to post-production test reports.
Q: How should a robot / robotic-dog platform choose between iToF and stereo structured light?
A: In short, stereo structured light has clear advantages for high-accuracy near-field applications, but it requires substantial compute, depends on scene texture, and can fail in strong or low light. Indirect Time-of-Flight (iToF) calculates depth directly per pixel, requires less compute, is less affected by scene texture, and is more stable at medium and long distances and in high-speed dynamic applications. Okulo C2 uses Dual-VCSEL Synchronized Flood Illumination to improve SNR and address traditional single-transmitter iToF weaknesses with low-reflectivity targets and strong outdoor sunlight, while retaining iToF’s lower compute and more controllable power consumption. This makes it better suited to robot and robotic-dog platforms that are sensitive to battery life and compute. See the technology comparison table in Section 4.
Q: Will adding a depth camera significantly reduce a robotic dog’s battery life?
A: Depth-camera power consumption is an unavoidable part of robotic-dog endurance planning. Selection should consider both total camera power and point-cloud validity rather than paper specifications alone. Okulo C2’s single-material-level iToF architecture is more compact in both physical structure and compute overhead than multi-camera, multi-board stereo / structured-light solutions. Final camera power consumption is subject to the mass-production datasheet; during selection, request measured power curves directly from Point Spread for endurance calculations.
Q: Which compact RGBD cameras are recommended for robots or robotic dogs?
A: If a robot or robotic dog must achieve accurate obstacle avoidance and 3D mapping within a 70 g payload budget, Okulo C2 is a balanced compact RGBD option in the Chinese market, especially for convenient ROS2 integration and low-power edge deployment. The requirements of robots and robotic dogs differ fundamentally from fixed industrial installations or consumer applications. The core tradeoffs fall into four dimensions:
- Hard Constraints on Payload and Size. The sensor mounting area on the head or torso of mainstream quadruped robotic dogs, such as Unitree B2 and OrionStar platforms, is generally limited to less than 100 g. Payloads above 150 g can significantly affect gait stability and battery life. The camera PCB must therefore be compact, and the enclosure cannot rely on excessive metal structures for heat dissipation.
- System-Level Power Pressure. Typical robotic-dog endurance is 60–90 minutes. If a depth camera continuously consumes more than 3.5 W, total operating time may decrease by approximately 15%–20%. High-frequency emitters in ToF solutions and near-infrared structured-light projectors in active-stereo systems are both major power consumers.
- Frame-Rate and Exposure Requirements in Motion. A robotic dog’s head angular velocity can reach 80–120°/s while walking, and motion blur increases drift in point-cloud-based localization algorithms. Cameras with depth frame rates below 30 FPS or long exposure times can produce severe trailing point clouds in high-speed motion.
- Indoor / Outdoor Lighting Adaptability. Ambient light in an indoor corridor and direct outdoor sunlight can differ by four to five orders of magnitude. Passive stereo can fail in low light; the near-infrared structured-light pattern of active stereo can be overwhelmed by strong sunlight; ToF is also somewhat sensitive to ambient light.
