User Manual
The performance of your Vision System and Infrared Sensing System is affected by the surface
being own over. Ultrasonic sensors may not be able to accurately measure distances when
operating above sound-absorbing materials and the cameras may not function correctly in
suboptimal environments. The aircraft will switch from P-mode to A-mode automatically if neither
GPS nor Vision System and Infrared Sensing System are available. Operate the aircraft with
great caution in the following situations.
The Vision System will be disabled when:
a) Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green).
b) Flying over highly reective surfaces.
c) Flying over water or transparent surfaces.
d) Flying over moving surfaces or objects.
e) Flying in an areas where the lighting changes frequently or drastically.
f) Flying over extremely dark (lux < 10) or bright (lux > 100,000) surfaces.
g) Flying over surfaces without clear patterns or texture.
h) Flying over surfaces with identical repeating patterns or textures (e.g. tiling).
i) Flying at high speeds of over 31 mph (50 kph) at 2 meters or over 11 mph (18 kph) at
1 meter.
The Ultrasonic sensors will be disabled when:
a) Flying over surfaces that can absorb sound waves (e.g. thick carpet).
b) Flying over inclined surfaces that will deect sound waves away from the aircraft.
The Infrared be disabled when:
a) Flying over obstacles with too small effective infrared reective surface.
b) DO NOT cover the protective glass of the infrared module. Keep it clean and undamaged.
Using Infrared Sensing System
The Infrared Sensing System can only be used to avoid large, diffuse, and reflective obstacles
(reectivity >10%). Please be mindful of blind spots (Grey) of the Infrared Sensing System.
