Stop Position Accuracy
When Kachaka reaches a destination, it does not stop on the exact same spot every single time. Stop position accuracy varies with the surroundings, typically landing within 5 to 15 cm.
Because Kachaka estimates its own position from the map before parking, accuracy depends directly on map quality. When the map lacks detail, or the real space does not match the map well, the parking error grows larger.
What affects accuracy
Accuracy comes down to how easily Kachaka can recognize its own position near the destination:
- Around 5 cm (tighter): There are structural features near the destination — wall corners, pillars, door frames — so Kachaka can readily match its position against the map.
- Around 15 cm (looser): The destination sits in an open space, or there are walls but the layout is plain and featureless — for example, a long flat wall with no protruding pillars and no doors. With few reference points to match against, parking is looser.
In short, the more feature points near the destination, the more precisely Kachaka stops.
Improving accuracy
If you need tighter stopping, there are two things you can do:
- Improve the map. Accuracy is anchored to the map, so building a solid map is the fundamental fix. For preparation and on-the-move tips, see Map Prep and Accuracy Tips.
- Use wall-marker stopping (Kachaka Pro). Kachaka Pro can read a dedicated marker placed on the wall directly above a destination and stop with high precision when carrying furniture — ideal for commercial settings with strict spot requirements.
