SIGMA ROBOTICS 西格瑪機器人 SIGMA ROBOTICS 西格瑪機器人 Japan's Preferred Robotics Kachaka Pro — the narrowest body of any commercial transport robot, made in Japan, with a four-year whole-unit warranty. No magnetic tape, no construction work; go live the same day with just a phone and WiFi. For how the brain layer works, see the AI solution →.
The robotics spin-off of Japanese deep-learning leader Preferred Networks
Per Fuji Keizai's 2026 survey, first in autonomous mobile robot units in the Japanese market; deployed by DENSO, KDDI, Asahi Kasei and others.
Winner of the Minister of Internal Affairs and Communications Prize at the Robot Award of Japan, Good Design Award 2023; co-developed station applications with JR East (2026).
