ATMega32u4 powers Hex ‘copter

Hex – powered by Atmel’s ATMega32u4 – is a 3D-printed nanocopter that can be controlled using the gravity sensors in a mobile device.

“Hex imitates the movement of the smartphone or a tablet in the air. In addition, traditional throttle, elevator, aileron, rudder control systems can be used to operate your Hex,” the HexAirBot team explained in a recent Kickstarter post.

“Hex’s flight control system is paired with various sensors help to make flying more safe and steady. These components massively reduce the risk of crashing. The sophisticated electronics in the copter allow it to sense when Hex is not balanced and adjust the motor speeds accordingly.”

The Hex team also noted that the open-hardware ‘copter allows users to view the world from a different perspective, as a camera can be easily attached to the ‘copter for aerial photography and videography. Plus, with FPV (first person view) glasses provided in the Hex Spy Kit, aerial navigators can realistically experience the thrills and joys of being in the air.

Last, but certainly not least, Hex’s autopilot system allows the craft to auto-balance itself in mid-air, although the sam circuit board can be modded to balance other devices such as a two-wheeled robot car, fixed-wing aircrafts, camera gimbals and submarines.

In addition to Atmel’s versatile ATMega32u4, key Hex hardware specs include:

• Propellers (size: 56×8.5 mm, fits shaft: 1.0 mm)
• Motors (diameter: 7.0 mm, length: 20 mm, over 50,000 RPM)
• Flight control system (Microwii Copter, MPU6050)
• Flight Time: 7 minutes
• Communication protocol: Bluetooth 4.0 (WiFi module for webcam)
