Right (Airflow Side)
Within 3 m (≈ 10 ft)
The Blower pauses the auto plan, shuts off the fan, and plays a “Person detected” or “Animal detected” voice alert. The system uses a wider detection range here because this is the discharge side where air velocity is strongest.
When Yarbo is traveling along a Pathway and detects a vehicle or large obstacle, it will perform a confirmation sequence before taking action — reducing false stops caused by misidentification:
Initial detection — Yarbo reverses 30 cm, then moves forward 25 cm to reconfirm whether an obstacle is present
No obstacle confirmed — Yarbo resumes the plan normally
Obstacle still detected — Yarbo repeats the confirmation sequence up to 2 more times (3 attempts total)
If any attempt finds the path clear, Yarbo resumes the plan
If all 3 attempts confirm an obstacle is present, Yarbo pauses the plan
Behavior after 3 confirmed detections:
If Yarbo is leaving the docking station, it will return to the docking station
If Yarbo is returning to recharge, it will pause the plan and notify you in the app
Note: This confirmation logic reduces unintended stops caused by people walking past the mower or brief misidentifications, while still protecting Yarbo from navigating into genuinely blocked pathways.
When the Blower detects an obstacle within 1.5 m (≈ 5 ft) behind it:
It slows down to about 0.3 m/s.
After closing the gap by about 1 m (≈ 3 ft), it performs an in-place zero-turn maneuver.
The unit adjusts its path to move around the obstacle on the already-cleared side, keeping the blower running so that leaves continue moving in the intended direction instead of being scattered backward.
If light contact occurs, the bumper triggers immediately—the Blower backs off, changes its angle, and resumes blowing safely.
The collision bar is always active, serving as the final safeguard. When light contact happens, the system instantly triggers a back-off and re-approach maneuver from a safer angle.
