#SENTRY GUN DOWNLOAD#

You can download all materials in the GitHub Repository. The Nerf Sentry Gun is comprised of entirely open source hardware and software. Nerf Sentry Gun Schematics, Source Code, and Documentation The entire setup is on a cardboard sheet to maintain proper spacing. This motor setup is attached to two metal napkin holders (totally not stolen from a dining hall) using gorilla glue. To compensate slightly for this, we made the battery pack external to reduce weight on the motor. This is why the gun turns somewhat slowly. Unfortunately, this motor does not provide a huge amount of torque. Modifying the original tripod mount allowed us to attach it fairly easily. The schematic for this circuit is included in the download below.Ī futaba servo is attached to the bottom of the gun. Sending this circuit a 5V signal from the DAQ tells it to close the motor circuit and fire the gun. This sends a 5V signal to the stamp on this channel so the stamp knows to stop rotating the motor.Ī trigger circuit was assembled in the handle of the gun it runs in parallel with the existing trigger, so the gun can still be fired manually. When the gun rotates all the way in one direction, a hook on the gun attached to a 5V rail makes contact with a hook connected to the basic stamp. It also interfaces to two hooks that sit behind the gun and act as limit switches. Upon receiving an input signal from the DAQ, it will rotate the servo right or left (depending on which input was activated). MATLAB can be used to turn these outputs on or off at the appropriate times.Ī basic stamp was responsible for controlling the rotation servo. Outputs 1 and 2 connect to a basic stamp motherboard for control of the rotation servo. Channel 0 outputs a 5V signal to a mosfet in the handle of the gun that activates the trigger. This digital I/O device was interfaced to MATLAB using the data acquisistion toolbox to allow for control of the trigger and gun. A custom MATLAB GUI is used to switch between modes, change color maps, and more.

#SENTRY GUN SOFTWARE#

Scale-Invariant Feature Transform (SIFT) image recognition software is used to identify a badge in authentication mode. A USB webcam and the image acquisition toolbox allow MATLAB to capture a video stream and analyze frames to ascertain velocity vectors. How it WorksĪ MATLAB program is responsible for performing all image tracking tasks. Arrow keys rotate the gun, and the space bar fires. The Novan Elites make limited use of automated sentry gun units for static defence and area denial, programmed with identify friend or foe software they.

#SENTRY GUN MANUAL#

Manual Mode: Allows you to control the gun manually. Panic Mode: Plays a siren, turns on the gun, and rotates the gun semi-randomly. This information is twittered as well( Freefire Mode: Tracks and shoots anything that moves.

Anybody who enters has their image uploaded to the web ( ) along with the date of entry, and whether or not they were approved to enter. If they do not comply, the sentry gun will track their movement and fire darts at them. System Walkthrough and DemoĪuthentication Mode: In this mode, anybody moving in front of the sentry is prompted to display their badge. The blog post also includes lots of pictures. Be sure to check out the github link below – This project was extensively documented. This is one of my most popular projects, with over 300,000 views on youtube. When a trespasser is detected, their image is uploaded to twitter and a website, then the gun tracks their motion and fires nerf darts at them until they have been “neutralized.” At the moment, it seems that having to drive at slow speed makes players enough of an easy target that the Sentry Turret won't necessarily be game-breaking, however, if players start to perfect the strategy enough, it may become the new meta for the latest Warzone patch.Sick of pesky intruders breaking into your secure facilities? Worry no more! The Nerf Sentry Gun uses MATLAB-based image recognition and motion tracking to identify trespassers and only permits entrance to those who present the proper credentials.

#SENTRY GUN PATCH#

It is unclear just how powerful this strategy is yet, and whether it is something that Raven Software will look to patch in the future. It can be difficult enough to deal with trucks in Warzone, so the addition of a mounted, AI-controlled Sentry Turret only makes things more challenging. Players have been posting up videos and screenshots across social media of them mowing down targets with the new strategy, and it has certainly brought vehicles into the limelight as a point of interest. Place this along the center of the field, as it has a rather short range.

They have limited ammo and can only be 'refilled' by placing down another one. It holds limited ammo and will cease to function once it runs out.

#SENTRY GUN DRIVERS#

There are some caveats to this James Bond-style vehicle though, as drivers will have to keep the vehicle moving at a slow and steady pace, due to the Sentry Turret struggling to fire at enemies while the truck is moving too quickly. A deployable sentry that automatically shoots zombies within a 80 stud radius, first attacking the zombie closest to it. Turret on the truck trick works, just remember to drive slow.
