**WARNING: not extensively tested**
|
2021-12-27 14:23:58 -05:00
|
|
|
There are still a lot of things to be tested.

|
|
|
The example code is now working to show the concept.

Radar is a concept library (not elaborated) that implements a Ping))) based Radar
|
|
|
|
|
with the use of two pan and tilt servo's.
|
|
|
|
|
It was written after a question on the Arduino forum but never finished or tested it.
|
|
|
|
|
Still, it has some interesting concepts with respect to how to determine the position
|
|
|
|
|
of pan/tilt while the movements are in progress.
|

|
|
|
|
|
|
|
|
The idea is that one knows how fast the pan and tilt servos are working in degrees per second.
|
|
|
|
|
From that number and the start moment one can determine approximately its position.
|
|
|
|
|
|
|
|
|
|
Given its position while moving is interesting for radar purposes as one can determine e.g.
|
2021-12-27 14:23:58 -05:00
|
|
|
in which direction a ping is given and therefore which distance belongs to which pair of angles.

## Future
|
|
|
|
|
|
|
|
|
|
- improve documentation.
|
|
|
|
|
- test more (e.g. continuous servo versus 180 servo).
|
|
|
|
|
- add sketches.
|
|
|
|
|
- remember lastPing (angle pan tilt).
|
|
|
|
|
- check TODO's in code.
|
|
|
|
|
- single servo radar (Pan only) as derived class.
|
|
|
|
|
- dynamic allocation of position arrays.
