Top failure modes
Ranked by count. Parentheses show change vs. Week 16.
Repeat site issues
Sites with 3+ failures of the same type this week.
| Site | Failure mode | Count | Weeks running | Recommendation |
|---|---|---|---|---|
| RL-PHX-03 | Mapping · site change | 14 | 4 | Refresh map — new rack layout installed 3/31 not yet in deployment. |
| RL-DFW-07 | Blocked aisle · zone 4B | 22 | 3 | Ops to review pallet parking SOP for third shift. |
| RL-ATL-02 | Docking · charger C-3 | 9 | 2 | Hardware check recommended; isolated to one dock. |
| RL-ORD-01 | Human interference | 11 | 2 | Operational, not product. Raise with facility lead. |
Robots with unusual failure rates
Deviations > 2σ from fleet median this week.
| Robot | Site | Runs | Failures | Rate | Primary mode |
|---|---|---|---|---|---|
| R-12 | RL-PHX-03 | 38 | 17 | 45% | Navigation failure |
| R-24 | RL-DFW-07 | 41 | 14 | 34% | Blocked aisle |
| R-07 | RL-ATL-02 | 35 | 9 | 26% | Docking issue |
Operational vs. product signal
Our read on where each failure class originates.
Failures driven by environment, staffing, or site policy — not the robot or software.
- 142 Blocked aisles (pallets, shrinkwrap, spills)
- 48 Site layout changes not reflected in map
- 29 Human interference during active runs
- 11 Shift-handoff SOP gaps at DFW-07
Failures where the root cause is robot behavior, firmware, planning, or perception.
- 89 Navigation failures — R-12 disproportionate
- 71 Missed zones (path planner conservative)
- 37 Docking — hardware suspect at C-3
- 14 Edge-case behavior, unclear classification
Recommended actions
Concrete, ranked by expected impact.
- 01
Refresh map at RL-PHX-03
14 of 48 mapping failures trace to a rack layout change on 3/31. Updated map not yet deployed. Single change, ~30% weekly reduction in this mode.
- 02
Hardware check on robot R-12
45% failure rate vs. fleet median 8%. Primary mode navigation failure at dock pillars — consistent with encoder or LiDAR drift. Pull from rotation; bench-check.
- 03
Operational review at RL-DFW-07
Zone 4B pallet blockage recurring across 3 weeks, third-shift specific. Not a product problem; raise with facility lead.
- 04
Dock C-3 at RL-ATL-02
Charging failures isolated to one dock across 2 weeks. Likely contact or firmware-on-dock. Swap dock or firmware update.
