A system that takes a picture of a moving object and uploads the picture to an embedded web server.

The system uses an ultrasonic sensor as a radar that moves from 0 to 180 degrees with the help of a servo motor. If the radar detects an object within 1 meter, it will stop and communicate its current position to the Raspberry Pi. The Pi camera will take a picture of the object which is uploaded on the webserver hosted on Apache (a hosting service that is integrated in the Pi). The Pi will then send the position of the object to the servo motor controlling the semi-automatic gun and the gun will fire at the target.

Here are some pictures of the system:

The system as whole wroked fine but there were some issues with the gun. The gun uses two DC motors and are very close to each other in the 3D printed gun. The problem with that design is that the magnetic fields of the 2 motors cancel each other which prevented the motors from spinning (and therefore prevented the gun from shooting the aluminium foil projectile) in the video. There will be an update to the design.
