Efference builds robotics-grade stereo vision cameras that treat depth as a software problem: cheap, noisy passive sensors paired with a proprietary 3D perception model that fuses stereo triangulation with learned environmental priors. Its H-01 is a passive stereo system with dual 5MP global-shutter sensors on a 60mm human-eye baseline, streaming RGBD video with dual 400Hz IMUs for low-latency visual-inertial fusion. The M1 targets distributed robot data collection at scale and the H1 targets real-time cloud inference with foundation models. The company sells vision hardware plus perception software to robot developers (humanoids, drones, autonomous vehicles) rather than shipping a robot itself.
