The gun has the ability to scan its field of view using a camera and can fire automatically at the target.
#AUTONOMOUS SMART SENTRY GUN CODE#
The camera will scan the object depending upon the Arduino code and the feedback is sent back to the Arduino controller. The Tilt servo motor controls the up-down movement of the gun and the remaining servo motor is used to squeeze the trigger of the gun. The Pan Servo motor controls the side-to-side movement of the gun. Three servo motors are used to control the movement of the gun and base, such as œPan control servo motor, œTilt control servo motor and œTrigger control servo motor. An Arduino is a microcontroller, which can be interfaced with the computer and can control the servo motor. The main components of the project are Arduino, Servo motor, Camera, Paintball gun. Overall, this system has a lot of potential in the modern-day military strategy and would help soldiers in the field of operation. The system would replace the active function of an armed guard while keeping a human life out of harm. As per todays military status, this system is not readily used by the military even though it has a greater potential. The sentry gun uses a camera based weapon system to detect/track a target and hardware to aim and fire at the target. It is a gun which is automatically aims and fires at the targets that are detected by a camera. The UA 571-C is one of a family of remote sentry systems including the -D variant, which mounts a 20 mW HF laser, and the -F version, which employs a 40 mm automatic grenade launcher.The project is concerned with the design and fabrication of sentry gun using Mechatronics System. The number of rounds fired in a burst is dependent on the target profile, so that the most economical use of ammunition is made. When the weapon fires, automatic servos in the tripod boresight the weapon on the target. If the system is set to 'manual override' or 'semi-automatic', this information is flashed back to the command console, where the system operator can decide whether or not to fire. If the IFF return is positive, the weapon will let the soldier or vehicles pass otherwise it will open fire. All Colonial Marine personnel and vehicles carry an IFF transponder in their communication gear which sends back a coded radio signal when interrogated. If the sentry is set to 'auto-remote', it will interrogate all targets in its sensor cone, using an Identification Friend Foe (IFF) transponder.

However, the system is usually set to multi-spectral mode, where the sentry's software cross-correlates received data from the different sensors to obtain a full target profile.
If a target’s visual or thermal profile is known, the system may be set just to monitor those specific targets using infrared or optical. This sensing suite consists of a cooled infrared detector in the 3-5 um and 8-13 um band, ambient light optics, an ultrasonic motion tracker and LIDAR ( Laser Imaging Detection And Ranging). The sentry unit's sensor array is mounted above the barrel, aligned to cover a 60 degree cone in front of the weapon. The weapon has a cyclic rate of 1100 rpm and is air cooled, with an automatic cut-out preventing the loading of any more rounds into the breech should overheating cause a chance of ammunition 'cook-off'. The UA 571-C mounts a pulse action machine gun, using the M250 10 mm x 28 HEAP round.
Once in place, the system may be set to sweep wide arcs up to 360 degrees (subject to terrain and emplacement restrictions), though doctrine is set to several sentries to cover smaller, interlocking fields of fire on a narrow frontage. A microwave datalink connects the sentry to a remote command console. The major components consist of a snap-open tripod mounting, battery pack, breech and barrel assembly, sensor unit and 500 round ammunition drum. A remote sentry unit weighs in at 19.6 kg and can be assembled in under 150 seconds. The UA 571-C is a man-portable automatic perimeter defense system currently deployed by the US Army and the Colonial Marine Corps.
