I've already read some stuff here on UWB positioning systems.
Their goal is it to find the 2D or 3D position of an tracked object.
In my project, I want a mobile robot to move always in the direction of a static target.
There are no obstacles in the area, and I have no knowledge where the static target is located in the area.
Besides the direction, I am actually not interested in the position of the robot nor the target.
Therefor I came to the conclusion, that a fully fletched indoor positioning system would be overengeneering.
It would be sufficient if I could just measure the distance of the robot to the target.
Then I could write a very simple algorithm to minimize the distance between robot and target.
Can I use UWB for just measuring the distance between to points without actuall positioning, and if yes, are there any examples?
The UWB transceiver modules do not find position. They measure distances, or can be used to transmit other data. Each module needs to be individually calibrated. Examples on this page:
The distance data can be used by another program to determine position.
So if I get this right I could add one of these modules to my robot, and another one to my target, then the robot can determine the distance to the target? (The target could also determine the distance to the roboto, but I don't need that information)
