Security V is a small security robot. It’s equipped with the following capabilities:

  • Automatic electric gun (Airsoft pellet gun) with ammunition cage
  • Pan-Tilt Gun Turret
  • Targeting laser
  • FPV Camera
  • (3) Ping sensors for object avoidance
  • LED Light Strips
  • MP3 Sound Player
  • IR Human Detection Sensor
  • Moto Controller
  • Two motors
  • Two treaded drive wheels and two omni wheels
  • Arduino Mega Microcontroller
  • Xbee Radio for remote control
  • Button panel for selecting the mode

We programmed it with five different modes:

1. Roams autonomously around the house, playing R2-D2 like sounds as it explores & avoids obstacles
2. Remote Control
3. Dance Mode (Plays the song Mr. Roboto and dances around)
4. Guard Mode (enables its infrared human detection sensor and plays a police siren if anyone tries to sneak past it)
5. Shoot (shoots the gun)

    Just curious what you used for the gun. Looks very small. I’m experimenting with a vision type targeting gun for a robot and looking for something small like that to experiment with.

    Ty J, That’s an electric air soft gun from an RC tank.

    Hi there. What chassis did you use?

    Hello, AW. We did not use a pre-made chassis. We fabricated it ourselves out of various aluminum pieces that we cut. The top piece is an aluminum perforated sheet, which we cut to size. You can get this material from,, and other places that sell metal sheet. The side, front, and back structure is made from C Channel, which you can get from various places. For example, Vex Robotics sells some: Here is another link: Here is another link (I think this is what we used):

    We used machine screws to hold it all together. The tricky part here, and in general, is mounting the motors and wheels. When you buy your motors, make sure you have a plan for the motor mount.
