Hi Talk Robotics presents its line of open-source bipedal humanoid robots, designed for education and scientific research. The company, based in Guangzhou, has developed its own actuators, which integrate a motor, reducer, driver, and encoder into a single joint module. This design allows for high-accuracy motion control. The robots are built on an open-source platform, enabling customers to perform secondary development and test their own algorithms. https://www.hightorque.com/

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

The product family includes the Minipai, a 7kg tabletop robot, and the Minipai Plus, which adds two arms and a head to the Minipai base. A larger model, also named Minipai, stands 90cm tall. The core of these robots is a main controller board designed in-house, featuring the Rockchip RK3588 system-on-chip. This provides the necessary computational power for tasks including AI model integration, though the models shown were not running AI during the demonstration.
One of the key features of the robots is their stability, which is managed by a proprietary algorithm. This allows the robot to automatically get back up if it falls over. The robots are designed to be robust and are capable of performing synchronized movements, such as dancing, and participating in activities like robot soccer games. The company has been developing this technology for five years.
Hi Talk Robotics also produces the individual actuators used in their robots. These are planetary-geared actuators designed and manufactured entirely by the company. This vertical integration gives them full control over the robot’s core components, from the joints to the main controller and battery systems. The company collaborates with universities worldwide, including Stanford and Tsinghua, whose teams use the robots for research.
This demonstration was filmed at the Hong Kong Fairs April 2026. The company, a startup with approximately 160 employees, including 60 engineers, is focused on providing a complete hardware and software platform for humanoid robotics research. They have plans to develop a larger, 130cm tall robot in the future, expanding their product line for more advanced applications.
