How does Loona perform obstacle avoidance?
Loona has a 3D-ToF (Time of Flight) laser sensor in front of the screen to sense the environment ahead, involving obstacles, cliffs, and objects that can be interacted with. Time-of-flight sensor (ToF sensor), is a range imaging camera system for measuring distances between the camera and the subject for each point of the image based on time-of-flight.
Sensor perception angle: horizontal 45°, vertical 45°
Sensor's farthest sensing distance: 3 meters
Sensor to distinguish minimum obstacles: height ≥3 cm
ATTENTION:
When Loona is on "Auto Pilot" or in the "Follow" mode, the ToF sensor will sense the environment ahead and plan a path for Loona to walk. However, when the App controls Loona or when performing movements such as dancing or voice command in a state of intense action, the function of the ToF sensor will be limited. Therefore, please ensure that Loona is in an open field when these functions are triggered to ensure safety.
Due to the limitation of the 3D-ToF operating principle, the recognition performance of the ToF sensor on the following types of objects will be decreased:
-
Direct sunlight
-
Mirror reflective objects (mirrors, bright reflective table legs, reflective floor, etc.)
-
Transparent objects (glass, fish tank, transparent plastic, etc.)
-
Pure black light absorbing object (such as black blanket, black matte object surface, etc.)
The current navigation experience of Loona has a lot of space for improvement. We will constantly strive to improve the recognition experience of Loona through algorithms and update it to all users via OTA.
Why does my Loona keep bumping into things?
Loona has a 3D-ToF (Time of Flight) laser sensor in front of the screen to perceive the environment ahead, obstacles, cliffs, and objects. Compared with the traditional laser, our sensor has incomparable advantages: like it can sense the 3D point cloud signal of the whole area in front of it, but it also encounters some limitations. Currently, Loona has occasional problems with obstacle avoidance and trajectory planning. We are trying our best to improve the experience through algorithms and update it to all users via OTA.

Keep the sensor cleanLoona's sensor is located at the bottom of her screen and should always be kept clean. You can wipe the sensor with a tissue. Meanwhile, do not cover some items (like decorations, etc.) on the sensor.

Limitations of Loona's object recognitionDue to the limitation of the 3D-ToF operating principle, the recognition effect of the Tof sensor on the following types of objects will be decreased:
-
Outdoor sunlight
-
Mirror reflective objects (mirrors, bright reflective table legs, reflective floor, etc.)
-
Transparent objects (glass, fish tank, plastic, etc.)
-
Pure black light absorbing object (such as black blanket, black matte object surface, etc.)

Loona may not recognize obstacles in these modesWhen Loona is on "auto pilot" or in the "follow" mode, the Tof sensor will sense the environment ahead and plan a path for Loona to walk. However, when the App controls Loona or when performing movements such as dancing or voice command in a state of intense action, the function of the ToF sensor will be limited. Therefore, please ensure that Loona is in an open field when these functions are triggered to ensure safety.
Can Loona sense obstacles in dark environments?
Loona's ToF sensor emits active light invisible to the naked eye so it can move around in dark environments. But Loona's sensors sometimes suffer from strong light.
Will my Loona fall off?
The current version of the Loona software is not yet supporting for use on the desktop, so please do not place Loona on the desk, which will cause Loona to fall off.
Meanwhile, please keep Loona away from the downward stairs to avoid Loona falling from that.
Loona's sensor can do edge detection, but it will take some time to tune and optimize the sensor's performance so that Loona can run in more scenarios. (Will be updated to all users via OTA)
