PrimeBot has officially released two consumer personal robots—Q1 and T1. The main focus of the hardware is on a mass-produced quasi-direct drive egg-shaped joint, which has a diameter of about 47 millimeters, weighs 260 grams, and demonstrates a stated peak torque density of 85 N·m/kg.
The PrimeBot brand (also presented as PrimeBOT on the company's website) is known in the domestic Chinese market through Pinyin transliteration within Swancor Advanced Materials, registered in Shanghai. The chairman of the materials parent company is Peng Zhihui, better known as Zhihui Jun, co-founder and CTO of AgiBot.
The Q1 model is positioned as a foldable humanoid robot approximately 88 centimeters tall and weighing about 15 kilograms. It is portable enough to be carried in a backpack or carry-on luggage and features full body force control, open SDK and HDK interfaces, as well as the ability to customize its appearance, movements, and voice.
The T1 robot, which is taller at about one meter and weighs 16 kilograms, is advertised as a transformable personal robot. It can switch between bipedal and wheeled humanoid modes, as well as a quadruped mode suitable for companionship both indoors and outdoors.
The standard versions of Q1 and T1 are priced at 19,999 RMB, while the Q1 Explorer and T1 Pro models are available for 26,999 and 29,999 RMB, respectively. Pre-orders began on August 23rd through the official mini-program and major e-commerce channels, with sequential shipments planned for October.
At a global product event held in September, these robots were presented as a way to enter the home companionship sphere, as well as for educational or content creation purposes, rather than for factory labor. Local reports mentioned the presence of demonstration stores in seven Chinese cities and partnerships with cloud assistants.
The primary emphasis in the development is placed on the small QDD joint, which ensures light and safe interaction in compact bodies, rather than on industrial load-bearing capabilities. The open software platform invites enthusiasts and researchers to customize it.
