Fig. 2. Solution elements<br />

The trigger <strong>in</strong> the presented system is based on a TowerPro MG-995 servomechanism,<br />

that presses and releases the Tippmann E-Grip automatic trigger. This is<br />

the easiest solution, that doesn't require any modification of the Tippmann's electronic<br />

components.<br />

Because the automatic turret presented <strong>in</strong> this paper was created to be a universal<br />

construction - compatible with any mechanical trigger firearm, only the automatic<br />

fir<strong>in</strong>g was done us<strong>in</strong>g the E-Grip electronic control board, that was powered<br />

by it's own 9 Volt Battery hidden <strong>in</strong>side the grip.
