The AgiBot D1 Ultra-W is the wheel-legged (wheeled) configuration of AgiBot's D1 Ultra quadruped platform, combining articulated legs with driven wheels so it can roll efficiently across flat industrial ground and switch to legged movement where wheels alone would stall. This hybrid locomotion suits inspection, security and patrol duties in energy, logistics, port and manufacturing settings that mix smooth corridors with kerbs, ramps and rough outdoor surfaces. Built for real fieldwork, it carries an IP54 rating with sealed, anti-corrosion construction for splashing, damp, dusty and sandy conditions, and at roughly 15 kg it transports easily and deploys by a single operator. A dual-encoder design makes it ready to use on startup with no zero-position calibration. High-torque actuation (about 48 N·m peak) and an embedded reinforcement-learning gait deliver self-balancing and disturbance rejection, while standardized Ethernet, USB, UART and SBUS interfaces with 12V/24V outputs integrate LiDAR, depth cameras, RTK and 4G/5G payloads.
