I wanted to do a small personal project to explore my Arduino kit and some basics. After some thinking, I decided to make a environment mapper with the Ultrasonic sensor (HC-SR04).
The idea is pretty simple, I would mount the sensor on top of a servo motor and rotate it degree by degree to get the distance between a objects/walls/etc and the sensor. I would then make a Python script to calculate the
In the first version, I hot glued the servo motor to my tripod and did the same thing for the sensor on a piece of cardboard.
It quickly became annoying to move the setup arround so I decided to make a second version.
I redid the wiring and remove the card board and the tripod (cause there was no use for it). I based my design on this project since we wanted to do the same thing.
When the setup was done, I continued the code I had to test the sensor and the servo. When the code was done, I began testing the scanning in corners, I quickly realized that the scanner wasn't doing great when the surface was in angle.
(That's supposed to be a
When the wall was in an angle, the signal didn't bounce back to the sensor, or it was bouncing back from a closer/further surface.
As you can see, the graph on my screen is not accurate in the corner part of the wall, the rest is fine.
