![]() If needed, the gun can also be controlled using a regular gamepad or joystick connected to the laptop. According to the designer, the sentry is extremely accurate and will even anticipate where a target is moving to so as to catch up with them. So if a person is wearing that symbol on their shirt, for example, then they can safely walk in front of the sentry, while everyone around them attempts to dodge a hail of darts.Īs it stands, the gun can be loaded with a 100-round ammo belt, which runs out quickly but could likely be expanded with a little extra modification. The webcam scans the area, while the program automatically locks onto movement, aims the gun, and begins firing.Īs a added feature though, the gun can be programmed to cease fire when it registers a particular symbolĪs a added feature though, the gun can be programmed to cease fire when it registers a particular symbol. Then it was just a matter of downloading and running an open-source program created by Bob Rudolph of Project Sentry Gun and affixing a webcam to the front of the stand. She also added a higher-voltage battery pack to raise the firing rate. Aside from giving the darts some extra punch, the increased speed also improved the gun's accuracy. While she was at it, she swapped out the Vulcan's usual 2 kg (4.4 lb) firing spring for a 5 kg (11 lb) one, upping the dart's velocity from 12 m/s (39 ft/s) to 90 m/s (295 ft/s). From there, Michelsen crafted a stand from plywood and mounted the gun onto a couple of servos, which also control its turning and tilting through the Arduino. Luckily, the Nerf Vulcan already operates using an electric motor, so controlling the actual firing mechanism through a computer was just a matter of connecting it directly to an Arduino Uno and a laptop. This isn't the first time she's modified a Nerf gun, but building this robotic turret is arguably her most ambitious project to date. Using a custom program and some servos, the sentry can automatically locate targets and unleash a stream of foam darts at over seven times the usual speed, while keeping its owner out of the crosshairs.īritt Liv Ulrike Michelsen, a chemical and biological engineering student from Germany, designed and constructed the sentry using mostly basic electronics and some plywood. In the real world, though, even a person's bedroom or office could use a little protection sometimes, which is why one designer has built the Nerf Vulcan Sentry Gun. It is used at various facilities in Qatar and the United Arab Emirates, including Abu Dhabi, among other places, and has been tested in the Korean Demilitarized Zone.Anyone who plays video games will know that few things protect an area like a well-placed sentry gun. The system gives a verbal warning before firing, and though it is capable of firing automatically, the company reports that all of its customers have configured it to require human confirmation. It is able to function during nighttime and is unaffected by weather conditions. In December 2010, the South Korean firm DoDAAM unveiled the Super aEgis II, an automated turret-based weapon platform that uses thermal imaging to lock onto vehicles or humans up to 3 km away. The same sources report that the weapons are mainly used for "warning shots" if they are fired at all, since the mere opening of the protective dome is often enough to intimidate any potential contacts into retreat. According to Israeli sources, the process to authorize a kill is "complex" but can still be carried out in under two minutes. The first reported killing of an individual appears to have taken place during Operation Cast Lead in December 2008. The weapon is capable of acquiring targets and maintaining a firing solution independently, but still requires human input to fire or release ordnance.ĭozens of people have been shot with the Sentry Tech system. The gun is based on the Samson Remote Controlled Weapon Station. Connected via fiber optics to a remote operator station and a command-and-control center, each machine gun-mounted station serves as a type of robotic sniper, capable of enforcing a nearly 1,500-meter-deep area of denial. The weapon is operated by one soldier and fed information from cameras, long range electro-optical sensors, ground sensors, crewed aircraft, and overhead drones, as well as radar. 50BMG automated M2 Browning machine gun and a SPIKE guided missile in each pillbox covered by an opaque protective shield. ![]() The 4-million USD (3.35 million Euro) system was completed in late spring of 2008. In 2007, the Israeli military deployed the Sentry Tech system, dubbed as the Roeh-Yoreh (Sees-Fires) by the IDF along the Gaza border fence with pillboxes placed at intervals of some hundreds of meters. It is a stationary system made by Samsung defense subsidiary Samsung Techwin. The Samsung SGR-A1 is a South Korean military robot sentry designed to replace human counterparts in the demilitarized zone at the South and North Korean border.
