Capabilities

Off-Device Model Inference

Designed to be the primary device for remote B200 cluster inference, with optimizations glass-to-glass. The same wireless stack supports seamless setup, data collection, and teleoperation, enabling full stack robotics under one device suite.

High-Performance Stereo Imaging

Two best-in-class 2.3MP global shutter sensors paired with wide-angle, low-distortion optics capture fast motion, diverse lighting conditions, and high-fidelity 3D vision. HDR support and superior low-light sensitivity deliver reliable performance across indoor and outdoor environments.

Dual 6-DOF Inertial Measurement Units

A proprietary sensor fusion stack combines image data with two 6-DOF IMUs through a fully hardware-synchronized pipeline, enabling ultra-low-latency pose estimation, localization, image stabilization, and high-frequency spatial awareness.

Neural Depth Inference

NPU acceleration and direct memory access provide the lowest latency path toward high-fidelity depth sensing out of the box, enabling mission-critical perception without unnecessary data movement.
