Why outdoor AMRs need GMSL cameras, and how the Gemini 335Lg delivers
USB has been the default interface for stereo depth cameras since the category existed, and it works fine on a robot that stays indoors on smooth floors within a few meters of its compute box. Push that same robot outdoors, onto a longer chassis, or into a route with vibration and electromagnetic noise, and USB starts to show its limits. That gap is exactly what the Orbbec Gemini 335Lg GMSL stereo camera was built to close, and it's worth walking through why GMSL matters before looking at what the camera itself does with it. What USB gets wrong for robots in motion USB 3 cable runs top out around 3 meters before signal integrity becomes a problem, which is a real constraint on AMRs where the camera sits at the front of the chassis and compute lives further back, or where a sensor mast needs distance from a vibrating drivetrain. USB connectors also aren't locking connectors. On a robot that's accelerating, braking, and crossing uneven terrain all day, a connector that can work loose under vibration is a maintenance problem waiting to happen, and an intermittent camera disconnect mid-route is a worse failure mode than a camera that never worked at all. Add electromagnetic interfere...
