Servo power switch - if you want to add your own external switch, you can bypass the switch on the board by wiring directly to the solder connections labelled "Bypass" on the bottom of the board.

Wire the - terminal of the battery to the "GB -" connection on the Sentry Controller.

Wire the + terminal of the battery itself to the "GB +" connection on the Sentry Controller.

Wire the black (-) wire of the battery plug to the "GM -" connection on the Sentry Controller.

Wire the red (+) wire of the battery plug to the "GM +" connection on the Sentry Controller.

With the trigger held down completing the circuit, the battery plug now provides direct connections to the electric motor inside the gun.

Use a zip tie or hose clamp to hold the gun's trigger in the squeezed position.

Find the plug that the gun's battery normally would plug into (if used in normal gameplay).

Besides eliminating the cost and weight of one servo, this gives the sentry a slightly faster response time. If you have an electric airsoft gun (or some paintball guns with electric triggers), you can replace the trigger servo with a direct electrical connection to the gun. You'll need a logic-level N-channel MOSFET transistor for this (Q1 in the schematic below). This reduces weight and improves response time. If you are using an electric airsoft gun, this allows you to wire the Arduino directly to the electric motor inside your gun, instead of using a trigger servo.

Electric trigger function - this one is tough to wire up, but very useful.When the plate is shot, the sentry is disabled for 8 seconds. This usually takes the form of a small metal plate mounted on a hinge on the front of the sentry, with a button placed behind it. To fix this, you can add a disable plate. Disable Plate - in a paintball or airsoft game, the sentry can be unfair and take the fun out of a game.Flip the switch back to the 'off' position, and the sentry resumes it's automatic targeting. This functionality helps when the gun runs out of ammo and you need to reload it, as it holds the gun stationary while you reload. When the switch is flipped 'on', it overrides the automatic targeting and puts the sentry gun in the "Reload Position" - the default servo positions that are defined in the Arduino code.

Reload Switch - this switch usually goes on the back of the sentry.

Fire tells when the software is firing, status shows the mode the software is running in, USB shows if the board is receiving commands via USB, and Power shows if the board is getting power via USB. Power, Status, USB, and Fire indicator LEDs - these LED's will light up as indicators.Basically, it claims to be able to “identify and shoot a target automatically from over two miles (3.2 km) away.” Scary! When used on the DMZ, this robot will not distinguish between friend or foe – anyone who crosses the line is deemed as an enemy. It will make use of its IR and visible light cameras to track multiple targets and remains under the control of a human operator from a remote location. The whole idea of the Samsung SGR-A1 is to let this military robot sentry do the work of its human counterparts over at the demilitarized zone at the South and North Korea border, so that there will be a minimal loss of life on the South Korean side just in case things turn sour between the two neighbors.įirst announced in 2006 (where obvious improvements have been made since, and I am not surprised if much of it remained as classified information), this $200,000, all weather, 5.56 mm robotic machine gun also sports an optional grenade launcher. The SGR-A1 will be able to detect intruders with the help of machine vision (read: cameras), alongside a combination of heat and motion sensors. A Samsung Group subsidiary has worked on a robot sentry that they call the SGR-A1, and this particular robot will carry a fair amount of weapons that ought to make you think twice about crossing the borders of South Korea illegally – as it has been tested out at the demilitarized zone along the border over with its neighbor, North Korea.
