The Unitree R1-A7 Smart D is a Smart package of the R1-A7, the fixed-base version of Unitree's seven-joint dual-arm humanoid. It is built to be mounted at a workstation — a bench, a table, a test rig or a cell — and to work the space around it: 555 mm of forearm and upper arm on each side, a waist that turns ±150° and a head that pans ±115° and tilts ±36°.
That waist range is the practical difference from the wheeled R1-A7-D, whose waist turns ±35°. Smart D gives up the chassis and its LiDAR, but it can swing both arms round to work on either side of its base, or turn from one fixture to another without moving. The robot measures about 835 × 357 × 190 mm and weighs about 13 kg on external power, and each arm handles 2–4 kg depending on posture.
Smart D is one of eight Smart packages, A to H, on the R1-A7. They share this robot and are sold as separate packages; the Smart D quotation itemises its end effector (two-finger gripper, three-finger or five-finger dexterous hand), any wrist camera and any high-computing module.
Onboard it has 8-core CPUs in the body and the head, 10 TOPS of AI compute in the head, a binocular camera, a four-microphone array and two speakers, with WiFi 6 and Bluetooth 5.2. It runs on external power or a Li-ion battery, and the arm, audio, lighting and vision interfaces are open for secondary development.
Key Capabilities
-
Built for a workstation: The fixed base mounts the robot at a bench, table, test rig or cell.
-
±150° waist rotation: Both arms swing round to work on either side of the base, against ±35° on the wheeled R1-A7-D.
-
555 mm arms: Seven-joint arms with 555 mm of forearm and upper arm cover the space around the station.
-
Head that follows the work: The neck pans ±115° and tilts ±36° to keep the binocular camera on the task.
-
Compact footprint: About 835 × 357 × 190 mm and 13 kg on external power.
-
Smart D contents itemised: The end effector and any wrist camera or high-computing module in Smart D are listed on the quotation.
