HaiClimber from HAI Robotics is the core robotic unit powering the HaiPick Climb system, designed for high-throughput warehouse automation with increased storage density and flexible workflow support. It moves freely up, down, and beneath racks at up to 4 meters per second, accessing any tote without fixed retrieval paths or restricted storage zones, enabling delivery to picking stations within 2 minutes. Its compact structure enables narrow aisles and efficient rack layouts with a special picking method capable of retrieving double-deep totes, increasing overall storage density while maintaining fast inventory access.
