Canonical robot record
Overview
The Unitree Z1 is a lightweight six-axis collaborative robotic arm built to extend the capabilities of Unitree's mobile and legged robots, while also functioning on a fixed base. Unitree describes it as able to move smoothly and perform fine manipulation tasks such as picking up small objects, opening doors, and fastening screws.
The arm provides force feedback and collision detection and supports both position and force control. It communicates over Ethernet and exposes an open programming and extended interface, allowing replaceable end-effectors and integration with platforms running Ubuntu.
Through its SDK, the Z1 supports upper-level control modes such as joint-space and Cartesian-space control, as well as low-level control of the underlying joint motors, giving developers a foundation on which to build their own control algorithms.
RoboZaps maintains this record as part of its canonical robotics database. Specs are source-verified where linked; the record compares public facts across manufacturers rather than representing a single robot maker.
