Yarbo Trimmer Operational Issues and Suggested Improvements

Issues observed with the Yarbo Trimmer during operation.

  1. Smart Turn / Reverse Behavior Near Perimeters and No-Go Zones
    During smart turns, Yarbo frequently reverses aggressively near perimeter edges and no-go zones. In many cases, this causes the trimmer head to dig into dirt, mulch, landscape beds, or uneven ground.

I believe the turning logic should be modified so that:

  • Yarbo avoids reversing when operating close to no-go zones or perimeter boundaries

  • Smart turns should be directed away from perimeter edges whenever possible

  • The system should prioritize forward pivoting or outward turning logic in tight areas to reduce trimmer head contact with the ground

  1. Trimmer Arm Extension Issues on Hills
    Another issue occurs when operating on downhill slopes around ~15% grade. During turns or certain maneuvers, the trimmer arm extends fully outward, which can cause the Yarbo to become stuck or short-cycle due to excessive resistance/load.

I believe an improvement could be:

  • If the trimmer arm is fully extended and the unit detects a stuck condition, Yarbo should attempt a recovery movement based on the previous direction of travel

  • Example:

    • If the last movement was forward, attempt a controlled reverse recovery

    • If the last movement was reverse, attempt a forward recovery

  • Potentially reduce arm extension aggressiveness while turning on slopes

These issues seem to happen more frequently around mulch beds, perimeter edges, and sloped terrain during autonomous trimming operations.
