Scuba S3 Obstacle Avoidance Not Working
The S3 uses ToF (Time-of-Flight) sensors for obstacle detection. If the robot keeps bumping into walls or obstacles, the sensor lens likely needs cleaning — or there’s a hardware fault.
The Scuba S3 relies on ToF (Time-of-Flight) sensors for obstacle detection and avoidance. If the robot repeatedly bumps into walls, steps, or other obstacles, the most common cause is a dirty sensor lens. Wipe all sensor lenses gently with a soft, dry microfibre cloth — do not use water, detergent, or abrasive materials. If cleaning does not restore normal avoidance behaviour, the sensor module may have a hardware fault requiring after-sales service.
How to Clean the ToF Sensor Lenses
Locate the ToF sensor lenses on the robot body — they are small, round, dark-coloured windows, typically positioned on the front and sides. Use a clean, dry microfibre cloth (the kind used for eyeglasses or eyeglass lenses). Gently wipe each lens in a circular motion. Do not use water, glass cleaner, or any solvent — these can leave residue that degrades sensor performance.
Normal vs. Faulty Avoidance Behaviour
With clean sensors, the S3 should slow down and change direction when approaching a wall, step, or large obstacle within a short distance from the obstacle. It may not avoid very small objects — the ToF sensor has a minimum detection threshold. If the robot collides at full speed with large, obvious obstacles despite clean sensors, the ToF module may be faulty.
When to Contact Support
If cleaning all sensor lenses does not restore normal obstacle avoidance, the ToF sensor module may have a hardware fault. Contact Aiper after-sales support with your device serial number (SN) and a description of the behaviour (e.g., ‘robot hits the same wall repeatedly at full speed’). Video footage of the collision behaviour is helpful for diagnosis. Do not attempt to disassemble the sensor housing — this voids the warranty.
