About the BUTLERBOT W3

The KEENON BUTLERBOT W3 is an autonomous indoor delivery robot designed for secure, hygienic, and contactless logistics in hotels, hospitals, offices, and other multi-storey buildings. Weighing 48 kg and equipped with up to four independently accessible enclosed compartments providing 90 L of storage and a 20 kg payload capacity, the W3 autonomously transports meals, medicines, documents, amenities, and parcels while maintaining privacy and hygiene through automatic compartment doors and active ventilation. Using LiDAR SLAM, dual stereo vision, IoT elevator integration, and intelligent fleet management, the W3 performs autonomous cross-floor deliveries, automatically calling and riding elevators without human assistance. Its long battery life, automatic charging, and multi-robot coordination make it a highly capable platform for 24/7 indoor logistics automation.
