What local positioning to apply?

Question

Arduino

I am planning something like a robot with a minicomputer and an arduino on board. I read that there are RTLS radio frequency positioning modules based on UWB technology that can determine coordinates with high accuracy. But, googling specific devices and modules did not bring any result. Maybe someone has already found and uses similar modules?

Answer 1

Without a clear TK, the result will not be very good.
Please describe your task in more detail.
I would stick cameras and build a 3d map of the area.

Answer 2

Google provides a bunch of links to businesses implementing this technology. But you probably don't have that much money. So, as always - to China! On Aliexpress, enter "uwb module" into the search. A lot of links, but the module is essentially the same - DW1000 or DWM1000. We return to Google, enter "DW1000 arduino", we get schematics, libraries, discussions ...

Answer 3

Don't want an IMU?

Answer 4

You can just use bluetooth tags. In version 5.1, the definition of the angle of arrival of the signal appeared, which should simplify the determination of the location of objects.
