What I'm curious about is how the sensors that enable the robot vacuum to move autonomously work. For example, how do they detect obstacles? How do they return to the wireless charging station? What is the foundation of these systems? Can you provide some technical details?
How do the smart sensors of a robot vacuum work?

Generally, robot vacuums use those IR sensors (infrared) underneath to detect furniture legs or the edges of steps, you know. For obstacle avoidance, they use LiDAR or ultrasonic sensors, which scan 360 degrees and create a 3D map, I’d say. As for wireless charging, they find the dock using magnetic field detectors and park automatically—pretty handy feature, in my opinion.
