[Artem Litvinovich] wanted to see by heat vision like in the Predator movies. He not only succeeded but went on to see in color, medium-wave IR, short-wave IR, and ultraviolet using a very unique approach since his effort began back in 2009.
He started with a box based on the basic pinhole camera concept. In the box is a physical X-Y digitizer moving a photodiode to collect the thousands of points needed to create a picture. First all he got, due to the high signal amplification, was the 60 cycle hum that permeates our lives. A Faraday cage around the box helped but metal foil around the sensor and amplifier finally eliminated the noise. Now he had pictures in the near infrared (NIR).

This Predator suit was premiered at this year’s Monsterpalooza conference. It’s nothing short of incredible. But the shoulder cannon is really what caught our attention. The thing is fully motorized and includes sound and light firing effects.
We saw a glimpse of what [Jerome Kelty] is capable of about two years ago. He was showing off an Arduino-based animatronics platform he put together for a Predator shoulder cannon that tracked based on where the predator’s helmet was pointing. But other than a video demonstration there wasn’t much info on the that actual build. This post makes up for that and then some.
A replica of this quality is rarely the work of just one person. A team of fans joined in to make it happen. After getting the molded parts for the backpack and canon from another team member [Jerome] set out to fit the support structure, motors, and control electronics into the space available. That meant a ton of milling, cutting, and shaping parts like the support arm seen above which integrates a servo motor into its rectangular outline. All of the controls fit in the backpack, with cables running to the helmet, as well as the cannon.

While the Kinect is great at tracking gross body movements and discerning what part of a person’s skeleton is moving in front of the camera, the device most definitely has its shortfalls. For instance, facial recognition is quite limited, and we’re guessing that it couldn’t easily track an individual’s eye throughout the room.
No, for tracking like that, you would need something far more robust. Under the guidance of [Krystian Mikolajczyk and Jiri Matas], PhD student [Zdenek Kalal] has been working on a piece of software called TLD, which has some pretty amazing capabilities. The software uses almost any computer-connected camera to simultaneously Track an object, Learn its appearance, and Detect the object whenever it appears in the video stream. The software is so effective as you can see in the video below, that it has been dubbed “Predator”.
Once he has chosen an object within the camera’s field of vision, the software monitors that object, learning more and more about how it looks under different conditions. The software’s learning abilities allow it to pick out individual facial features, follow moving objects in video, and can recognize an individual’s face amid a collection of others.
While the software can currently only track one object at a time, we imagine that with some additional development and computing horsepower, this technology will become even more amazing.

This Predator costume has an animatronic element in the shoulder cannon. It tracks the movement of the mask, aiming wherever the Predator gazes. [Jerome Kelty] was asked by a friend to help develop the costume and he ended up with an animatronics platform which can be adapted for many different uses.
Starting with an Arduino Pro Mini [Jerome] designed a host board which would breakout the pins of the Arduino and make it easy to connect and drive multiple servo motors. The board is powered by a 3.3v Lithium Polymer battery with charging handled by a MAX1555 that was included in the design. Check out the video after the break which shows off the Predator suit. Looks like [Jerome] got it right, and he’s also put the platform to use with an Ironman suit that has an arm-mounted missle feature.
Need some inspiration for you next costume build? Take a look at this animatronic collection to get you started.
