Mio stabilized camera or payload mount

The Two-Axis Mio is a two-axis stabilized gimbal from Gremsy for small cameras and sensors on unmanned aircraft. It holds an imaging payload steady and controls its pointing direction in tilt and roll, and is designed for front-mounted installation on industrial inspection and survey drones.

The gimbal weighs 180 g and measures 133 mm in depth, 101 mm in width and 94 mm in height. It carries payloads up to 400 g, so it fits compact RGB, thermal and multispectral sensors rather than heavy cinema cameras. The maker lists compatibility with several small sensors, including FLIR Duo Pro R, FLIR Vue Pro, Sony R10C, Sony QX1, MicaSense RedEdge-MX and Sony RX0. Low mass is a design goal: the unit weighs less than a third of the maker's original Mio, which helps preserve flight time.

Stabilization relies on an integrated IMU and motors with 14-bit encoders. The angular vibration range is +/-0.02 degrees. The tilt axis can be controlled over +/-127 degrees and the roll axis over +/-60 degrees, and each axis reaches a maximum controlled rotation speed of 100 degrees per second. Operating modes include follow mode, mapping mode and front mode, which correspond to pointing the camera with the aircraft, holding it fixed for survey passes, and mounting at the nose.

Integration is supported by an adapter board that exposes USB 2.0 (Type C), UART, SBUS, PPM and Micro HDMI connections, plus six auxiliary signals. Supply voltage is 14 V to 52 V, with a static current of 400 mA at 12 V and a locked-motor current of up to 1.7 A at 12 V. The gimbal speaks the MAVLink gimbal protocol and the maker's gSDK, and is listed as supported on Pixhawk-class, CubePilot and Skynode flight controllers. Third-party control is possible through SBUS and MAVLink. The unit mounts at the front of the aircraft with either standard damping or a custom damping system supplied for a specific airframe, and set-up software runs on Windows 10 or later and Mac OS X 12.0 or later. The operating temperature range is -15 degrees C to 50 degrees C.

The maker lists NDAA, Blue UAS, RoHS, CE and FCC among its trust marks for the product line. Typical applications are bridge inspection, wind turbine blade inspection and other industrial inspection, mapping and surveying where a small payload must stay stable during flight.
