H.J. Stauble with Aerobotics UAS Group is focused on technology solutions using UAVs (Unmanned Aerial Vehicles or “drones”), for high-resolution aerial data collection while minimizing human risk exposure.

Our UAVs are outfitted with stabilized High Definition optical zoom cameras, FLIR thermal imaging, and custom robotic attachments for precision applications. Each camera sensor has been designed to inspect, detect, and measure structural damage and potential failure(s).

We specialize in prevention and preservation of assets by replacing manned tasks with drone missions, which are less expensive, faster, more efficient, and much safer than traditional human risk exposure methods.

We are also pleased to offer the first collision-tolerant UAV, designed for confined space industrial and structural inspection inside tight, cramped, and often dark dangerous environments. The UAV comes equipped with both High Definition colour and Thermal Infrared cameras, powerful LED lights ready for your next confined area entry, and with our new long-range antennas, this UAV can be flown beyond visual line of sight over considerable distances.
