NAVIAI i3 (智御卫士, bei hg 'NAVAI-I3')

Built for mixed terrain rather than factory floors, NAVIAI i3, known in Chinese as 智御卫士 or All-Terrain Guardian, is a bipedal humanoid from the Zhejiang Humanoid Robot Innovation Center, which markets its machines under the NAVIAI brand. The maker stresses impact resistance and the ability to keep its balance after a disturbance, without quantifying either.

The robot is 1.80 m tall and has 37 degrees of freedom; joints deliver up to 360 Nm and the top speed is 9 km/h. Weight, carrying capacity, runtime, sensors and computer are not published. Software is released through the open ZJ-Humanoid organisation on GitHub, although how much of it covers the i3 is not stated.

Intended uses are guard duty, inspection and research, which points at research institutes and industry as customers. No market status is given, so the entry is recorded as a prototype with price on request. The centre claims to be the first to pass 2,000 humanoids produced, without saying how many are i3 units; its current range also includes the WA1 and WA2.

The institution's previous generation, shown in 2024, is described under Navigator 2.
