Frequently Asked Questions ▾
What makes Gemini 305 ideal for humanoid robot and cobot applications? ▾
The Gemini 305 is a lightweight 68g stereo vision camera specifically designed for robotic wrist mounting. Its ultra-close 4cm minimum range, sub-millimeter accuracy, and compact 42mm x 42mm form factor make it ideal for collaborative robots (cobots), humanoid robots, and pick-and-place applications requiring precise close-range depth sensing.
What is the difference between Gemini 305 and Gemini 305g? ▾
The Gemini 305g adds a GMSL2 serializer with FAKRA connector in addition to the USB Type-C interface. This GMSL2/FAKRA option provides flexible, low-loss cabling that better handles the challenges of constant twisting and bending in dynamic robotic arm motion.
What is the depth accuracy of Gemini 305? ▾
The Gemini 305 achieves sub-millimeter accuracy at 15cm and maintains spatial precision of ≤1% at 50cm (measured at 1280x800 resolution within 90%x90% ROI).
What resolution and frame rate does Gemini 305 support? ▾
Depth resolution: up to 1280x800 at 30fps. Color resolution: up to 1280x800 at 60fps. Both depth and color streams use global shutter sensors, ensuring sharp imaging of moving objects without motion blur.
What is the IP rating and operating temperature of Gemini 305? ▾
The Gemini 305 has an IP54 ingress protection rating for dust and splash protection. It operates in ambient temperatures from -10°C to 45°C.
What applications is Gemini 305 best suited for? ▾
The Gemini 305 is optimized for: Cobots (collaborative robots) with wrist-mounted vision, Humanoid robots for hand-eye coordination and dexterous manipulation, Pick-and-place operations requiring close-range accuracy, and robotic grasping tasks. Its 4cm minimum range and lightweight 68g design make it ideal for end-of-arm tooling applications.

Orbbec Gemini 305: 68g Ultra-Lightweight 3D Camera for Robotic Wrists

The Orbbec Gemini 305 is an ultra-compact stereo vision camera engineered specifically for robotic wrist mounting. Weighing a mere 68 g with dimensions of 42 mm x 42 mm x 23 mm, it features an IP54-rated housing and operates reliably from -10°C to 45°C. Powered via a standard USB Type-C connection, it delivers highly precise visual data for recognition and grasping on payload-sensitive collaborative and humanoid robots.

High-Performance Close-Range Perception
Designed to eliminate close-range blind spots, the camera boasts a minimum operating range of 4 cm and delivers sub-millimeter accuracy at 15 cm. Its proprietary decoupled depth-color design and dual-channel color capture stream depth resolutions up to 1280 x 800 @ 30fps and color up to 1280 x 800 @ 60fps. Utilizing global shutter for color imaging, it effectively reduces motion blur during dynamic robotic arm movement.

Seamless Synchronization & Flexible Imaging Modes
The Gemini 305 achieves multi-camera synchronization through both hardware-sync and software-sync methods, ensuring low-latency direct depth output down to 60 ms. Predefined imaging presets enable one-click switching between "Depth + Color" and "Dual-Color" streaming modes, allowing flexible configuration according to different using scenarios.
