R1-A7-D

R1-A7-D is Unitree's mobile dual-arm robot with seven-joint arms, a lifting column and a wheeled base. It is designed for developers working on manipulation, perception and human–robot interaction. A head-mounted binocular camera provides visual input, while chassis LiDAR supports the mobile configuration; wrist cameras and alternative end-effectors are optional.

The robot has 22 degrees of freedom with its grippers fitted and changes height for work at different levels. Unitree provides programming interfaces for the arms, vision, audio and other system controls, along with optional higher-performance computing modules. Its published arm-load range depends on the arm's extension and posture. R1-A7-D is distinct from the five-joint-arm R1-A5-D, the fixed-base R1-A variants and the walking R1 humanoid, each of which has a different mechanical configuration.
