Kachaka robots run PFN-lineage deep-learning autonomy: SLAM self-localization and mapping, sensor-fusion navigation combining three sensor types, image recognition for obstacle avoidance, and voice control. A 2024 update added large-language-model conversational operation with memory of past dialogue. Kachaka Pro adds a 12m-range LiDAR and 30kg towing capacity for larger commercial spaces, plus elevator integration for multi-floor operation.
