Unitree R1-A7-D Wheeled Humanoid Robot

Product Description

The Unitree R1-A7-D is the mobile counterpart to the R1-A7 — a legless dual-arm humanoid from Unitree's R1-D family, mounted on a LiDAR-equipped wheeled base for autonomous navigation and mobile manipulation. It extends the same humanlike reach and dexterity of the R1-A7's 7-degree-of-freedom arms to applications requiring the robot to travel between workstations, shelves, or task zones rather than staying fixed in one place.

Quick-fitted with two-finger grippers or three- and five-finger dexterous hands, the R1-A7-D achieves the same ±0.1 mm end-clamp accuracy and 2–4 kg arm loads as its fixed-mount sibling, with a telescoping torso that shrinks or raises the working height to suit different tasks and reach envelopes. Built for factories, labs, classrooms, and the data-collection economy, it converts the R1 platform into a mobile manipulation worker for applications where fixed-station mounting isn't practical.
