Arduino Animatronics Make Your Awesome Costumes More Awesome 1. Steps with PicturesExample 7 Predator cannon. Using a modified Wii nunchuck board we can make a head tracking system to control an animatronic Predator cannon. This system was designed to look like the cannon mechanism in the first Predator movie. The nunchuck board is removed from its case, the joystick is removed and the board is placed level in the top of the Predator Bio helmet. The wires are extended for the buttons so they can be used as fingertip buttons to activate the cannon and trigger the firing sequence. To remove the circuit board from the Wii nunchuck case youll need a tri wing screwdriver http www. OS 1. 3 7. 1 1e 4. The sound effect is handled just like the Iron Man repulsor in example 4 using the Adafruit Wave Shield. Since the Wave Shield code used can support six individual sounds you can add five other Predator sounds and activate them using fingertip switches neat There is one servo that is geared 4 1 that raises the cannon arm in the code you can see this as the servo rotating 1. The other two servos aim the cannon using the accelerometer inputs. There are transistors that turn on the aiming servos and laser sight when one button is pressed. If the aiming servos were always on then the cannon would rotate even when it was in the lowered position, so they need a way of being turned off when the cannon is lowered. So push one one button and the cannon raises up, the aiming servos turn on and the laser sight turns on. Push the second button and the cannon fires two transistors turn on the cannon LED and activate the firing sound. Three red LEDs can be used in place of the laser sight. The cannon LED can be anything from several small LEDs to a high power Luxeon LED. When using a high power Luxeon LED be sure to use a constant current driver to power it. Servos can draw a fair bit of power so I use a TIP 1. The prototype cannon mechanism was built using Delrin plastic scraps and timing belts and gears from old desktop printers and photocopiers I found in the trash.

For Predator costuming info check out http www. Those individuals interested in obtaining a resin cannon casting should contact my friend Carl here http www. Carls work is absolutely brilliant check out the photos below of the Predator backpack clay sculpt that he created for this project. Thats a lot of clay When contacting Carl please be patient as hes extremely busy and he has a large backlog of work.
