For many engineers, the NAB 2015 convention will be remembered for the high interest in UAVs (drones).
To say that UAVs have caught the attention of the video production community is an understatement. Not only did this year’s NAB conference showcase at least 24 different manufacturers, distributors, and service providers, but paper sessions and a dedicated Aerial Robotics and Drone Pavilion grabbed buyers’ attention throughout the show.
First, a brief summary of why there has been a sudden explosion of activity in this product development space.UAV technology – specifically, multi-rotor aircraft – is the direct result of a confluence of the following synergistic technologies:
- Highly-efficient brushless electric motors
- Lightweight high-capacity Li-Po batteries
- Sophisticated electronic speed controls
- Active stabilization
- Advanced wireless control
- Lightweight HD and UHD cameras
The details of these technologies form a topic for a separate article, as is the subject of the evolving FAA regulations concerning UAVs. Suffice to say that, at present, flying a UAV for a commercial purpose, without a flight waiver, is in violation of FAA Regulations, and can result in a stiff fine.
The UAV market can be broadly separated into three main categories: consumers (toys), hobbyists, and professional. Roughly speaking, each of these markets is dominated by small midsize and large aircraft, respectively. The capabilities and features of the UAVs tend to cross each of these categories (a “crossover” machine), but the higher-end machines are usually distinguished by the cost, reliability and support that is available. Most of these UAVs are “quad” platforms that consist of a main structural body held aloft by a motor-and-prop assembly at the end of each of four booms. Variants include 6, 8, and 12-boom models as well.
A number of companies have developed “smart” navigation features that allow even inexperienced pilots to achieve professional-quality results. Another interesting feature is the ability to fly from the aircraft POV (point-of-view, also called FPV or First Person View), a capability that can incorporate the technical and artistic abilities of the pilot.
Many of these companies are new entrants (many from China), essentially startups jumping on the opportunity bandwagon. Presented here is a roundup of the various UAV products seen at NAB, including various gimbals and video links.
The 3DR Solo is a crossover UAV with features like push-button flight commands and computer-assisted “smart shots.” Solo is powered by two 1 GHz computers – one each in the aircraft and pilot flight control – and includes several flight technologies and built-in safety and support features. Unique safety features like pause and “safety net” provide fail-safe recovery and flight.A “Follow Me” mode enables Solo to automatically track and film any moving object.
Technologies now under development by the company include LiDAR-stabilized indoor flight, a ballistic parachute system, and flight rewind. Future-proof accessory and gimbal bays provide flexible accessory mounting options. The 3DR Solo lists at $1,399.90 w/ gimbal, $995 w/o, and is slated to ship in late May.
The 3DR X8-M is a large quadcopter platform from for creating high-resolution aerial maps. The platform offers low-flying and high accuracy mapping, with a fully redundant propulsion system for increased reliability. List price is $5400
ACR Systems, ACR the Plus is a small-camera stabilizer system. By removing a top handholding module, the device becomes a gimbal/stabilizer which can be attached to a UAV. ACR The Beast is a large-camera stabilizer using active sensors and brushless motors.
AEE Technology recently introduced the AEE F50, a small drone with a built-in 16MP 1080p60 camera.Additional features include a telemetry “black box,” autopilot, 3D-camera, GPS and Wi-Fi.Flight ceiling is specified at up to 1500 meters (way past legal FAA space!), maximum airspeed of 80km/h (50mph), flight time of 40 min, and all-up weight of 2000g (4.4 lb).

By using a “Smart Mode,” the UAV will always fly, with respect to the ground, in whatever direction the control stick is pushed, independent of the aircraft’s orientation with respect to the pilot.There is also a SAFE Circle geo-exclusion feature that prevents the aircraft from flying too close to the pilot. For more experienced pilots, the 350 QX3 can respond to control inputs like a conventional RC aircraft, where the controls steer the aircraft with respect to the vehicle, not with respect to the ground. This gives the pilot more control authority by allowing steeper bank and pitch angles, and by turning off the SAFE Circle.
The 350 QX3 also provides the option of accessing an alternate set of stability and agility flight modes. These flight modes are programmed for experienced pilots who have mastered the basics and are ready for more aggressive response and aerobatic flight.

Fotokite Pro is a tethered flying camera system, designed by a Swiss startup company, that offers reliable and safe flight with a quick setup time. A tether provides a safe, direct way to fly; the visible, load-bearing physical link allows direct visual pilot accountability for bystanders and property owners.Because the tether supplies power from the ground, the Fotokite Pro can fly for several hours. Company personnel believe that, because of the safety afforded by the tether, operation may not require full UAV operator licensing.
The Fotokite requires no active pilot control – it flies like a kite, always with a line attached – but is remotely oriented using a smartphone or tablet.It has no GPS and no RF communications dependency; a live low-latency 1080p60 uncompressed video downlink enables framing and live broadcast over both HDMI and USB 3.0.
Operation is limited to 65ft (20m) in height, so it cannot fly into controlled airspace; the weight and length of the cable is the limitation. At 1.3 lbs (600 g), it has several safety features including emergency landing, tether-cut detection, and propeller-impact detection. Flight is sustained as long as power is provided from the ground: a small backup battery guarantees safe landing under all circumstances.
