I’m using mmWave for human presence detection, mostly to turn the lights on if someone is in the room. Those IR motion detectors have a problem where they will turn the lights off if a person does not move. But mmWave can detect breathing and heartbeats, and some of them can detect falls.
No calibration is needed if you buy the complete retail unit. The problem I have with them is they need about 1/2 Watt of power and can’t be battery-powered. But a coin cell will power an IR detector for a year.
They say “no-code” integration in 1 or 2 minutes. Yes, assuming you already have the infrastructure in place. This unit uses MQTT over WiFi.
Using a humanoid robot to move a camera around is not cost-effective. Just buy a few cameras and an AI-based monitor.
My plan for a domestic robot is that the house itself is the robot. Rather than sensors and AI in a humanoid robot, we can place the sensors on the wall and the AI in a closet. Then we need mobile devices to “do stuff."
The big problem is that our current AI is not good enough and will not become good enough by just incremental development. Like a locomotive will never fly even if we make the wheels a lot better. You need a different technology. Trains do transportation well. But airplanes fly not trains. Basically, our AI is like a train. It works, but we need breakthrough-level advancements. Gradient descent training over tons of data will only get you about what we have.
