Product overview
About Zerith Z1
Zerith Z1 is a full-body bipedal humanoid first presented on 24 October 2024. Contemporary launch coverage described a 27-degree-of-freedom prototype. A 2025 Zerith product matrix later listed a 1450 mm Z1 with 31 degrees of freedom, indicating that the current production configuration differs from the launch unit.
Zerith's current Z-series page specifies a 672 mm single-arm reach, a maximum payload of 1.5 kg per arm and 150 NĀ·m peak joint torque. It lists approximately 2.5 hours of operation and a removable, replaceable battery. The perception system combines multi-camera stereo vision with a six-microphone array. The company presents the platform for service and research applications but does not publish its weight, maximum walking speed, battery capacity or a public price.
Chinese launch coverage places the unveiling before Zerith Robotics' January 2025 incorporation, so the robot appears to have originated with the founding team before the company was formally established. A February 2025 report said Z1 production had entered mass production, and the current official page provides a sales-contact route. On that evidence, this entry is classified as commercial.
