Some manufacturers use cameras instead of LiDAR (iRobot, for example).
Others use both. LiDAR for walls, cameras for object identification below the LiDAR plane, directly in front of the robot. That’s how the fancy ones avoid socks or cables or other small things.
- supportengineer 2y agoThis might be OK for a vacuum cleaner, but nobody in their right mind would choose cameras over LiDAR for important applications.
- NRv9tR 2y agoIf I understand correctly Tesla is/has removed LIDAR and uses computer vision for most/all of their self driving. https://bdtechtalks.com/2021/06/28/tesla-computer-vision-autonomous-driving/ https://bdtechtalks.com/2021/06/28/tesla-computer-vision-aut...
- Alupis 2y agoYes, perhaps the single-most controversial decision Tesla has made regarding FSD. Everyone else uses LIDAR in some form. Tesla's cameras can and have been fooled on many occasions.
- bmicraft 2y agoYeah okay, but that doesn't mean _cameras_ are bad (which, to be fair, they are in Teslas case), it means the algorithms feeding on them are.
- Alupis 2y agoIt means the cameras can be fooled by things LIDAR cannot be. Such as smoke, glare, reflections, optical illusions/mirage, etc. If the algorithms are fed with incorrect data, they will produce incorrect results - such as driving full-speed into a parked, white colored, semi-truck.
- bmicraft 2y agoAnd lidar can't tell the difference between a plastic bag and a rock, what's your point?
- Alupis 2y agoOne can (and has been) fooled into thinking there is no object in the path - the other might be extra sensitive to any object in it's path. I'll let you stew on that one for a minute...
- bmicraft 2y ago> I'll let you stew on that one for a minute... Then that means the vision processing isn't far along yet to be viable for a car. There is no fundamental reason why it couldn't work though. With either stereoscopic vision or more temporal processing you could obviously detect when things are only painted on a wall surface, with both there really is no excuse to still fail except limited processing power.

- bonestamp2 2y agoI don't think Tesla ever used LIDAR and the article confirms they don't think they will need to. I believe they removed ultrasonic sensors though, maybe that's what you're thinking of.
- kelnos 2y agoAnd this is likely why Tesla's FSD is... not very good.
