I'm curious, what methods do robot vacuums generally use for obstacle recognition and navigation algorithms in homes? For example, is LIDAR dominant for scanning rooms, or are camera-based systems more efficient? What are the pros and cons of different approaches?
How do robot vacuums move autonomously?

Hahaha I'd be losing it trying to understand algorithms while building a PC too 😂😂 Don't forget mine, trying to figure out the robot vacuum's algorithm while dealing with a cable mess 😭💻🤪
Mostly we're seeing LIDAR-equipped robots popping up, bro, and I teach my students about this stuff in Arduino labs all the time. LIDAR does super precise measurements—it maps out the whole room and records every centimeter. Like, my workshop vacuum navigates without constantly smashing into walls thanks to LIDAR. Sure, there are camera-based systems too, but processing those images to figure out positioning isn’t easy at all. If the lighting changes or dust gets on the lens, the algorithms can go haywire.
I’d say LIDAR’s biggest drawbacks are the cost and power consumption. Cheap models have weak laser modules, so the battery dies in an hour just from constantly scanning the room. I swapped out the original chip in my vacuum for a third-party one, but that just added extra strain. The camera-based guys usually keep navigation simple, so they only clean specific areas. To decide which system’s more efficient, you gotta move the vacuum from room to room and see which one maps things out faster.
