iPhoneDrone Project – UAS Equipment

The sUAS market is blossoming at an exceptionally swift pace. Being that I did not have a hobbiest background before starting this project, I wanted to find a package that was easy to use and that I could operate right out of the box. Autonomous capabilities were a must, and most importantly, it needed to be reasonably affordable for a someone still in college.

IRIS Package Includes: Copter, Battery and Charger, Tools, R/C, Accessories

After seeing a presentation by 3D Robotics last August, I was sold on their products based on their prices and track record. The IRIS is 3DR’s flagship product. The quadcopter comes with everything necessary, including a battery and R/C controller, in a convenient package. Technicians even pre-program the R/C with 5 different flight settings.

The other key component necessary was the camera and camera mount. I had an iPhone already, so the camera was taken care of. Configuring a mount though was a major challenge since nothing exists on the market for iPhones. Copters by nature produce high frequency vibrations and without the proper mount, the vibrations will bleed into your photos/video. This effect is commonly referred to as “jello.”

As I came to find out, the iPhone’s CMOS rolling shutter sensor is especially susceptible to jello. To fix this, I ordered a vibration dampening mount made for a DJI Phantom. To my surprise, the mounting screw locations matched the IRIS’ bottom vents perfectly! After finding some go pro mounts, extension legs, and clear iPhone case, I had pieced together a vibration free fixed iPhone 5s mount for the bottom of my IRIS (See gallery below).

Since installing the mount, the images from my iPhone are now about 90-95% jello free. More experiments are under way to improve image quality even more, but for now, I’m pretty satisfied with the results.
