Beyond imagination, create possibilities. As of December 27, 2024, the humanoid robot track is booming, and the research on embodied intelligent humanoid robot technology is also in full swing. On December 26, GAC Group’s independently developed third-generation embodied intelligent humanoid robot GoMate made a stunning debut, attracting widespread attention due to its unique configuration design and unprecedented ability expansion.
At the launch event, GoMate was full of highlights. It pioneered the variable wheel-foot mobile structure in the industry. In the four-wheel-foot mode, it has all-terrain trafficability. It has achieved complete independent research and development of core components such as drivers, motors, and dexterous hands. It has excellent autonomous navigation capabilities and can accurately locate and flexibly avoid obstacles. The combination of remote control and AI large models endows the robot with a smarter brain.
Why is GoMate designed with a “variable wheel-foot mobile structure”?
The “variable wheel-foot mobile structure” is the biggest highlight of GoMate. In the field of humanoid robots, there are two mainstream technical routes for movement methods: wheeled and legged. Legged robots have high flexibility but insufficient efficiency and have not yet reached the commercialization level. Wheeled technology has obvious advantages in maturity, stability, and cost and has greater market potential. The robot research and development team of GAC Group anchors the “wheel-foot” technical route and creatively proposes a configuration that can switch between two-wheel feet and four-wheel feet, taking into account efficient movement on flat ground and adaptability to complex terrain, and solving the problem of full-scene passage of robots. In the stable state of four-wheel feet, the robot is about 1.4 meters high and is used to deal with complex road surfaces and extreme working conditions. In the two-wheel-foot standing posture, the height can reach 1.75 meters. The robot mostly completes daily tasks in the two-wheel-foot mode.
What are the advanced features of GoMate’s dexterous hand in research and development?
GoMate’s dexterous hand is independently developed by GAC Group. Its advanced features are reflected in: supporting multiple communication interfaces, with strong flexibility and compatibility, providing more choices for humanoid robots to communicate with environmental information; having a forward and reverse flexible protection design to effectively avoid accidental touch or overload damage; equipped with tactile and visual sensors, capable of adaptively adjusting the grasping force and posture; weighing less than 500 grams and with a load of 1.5 kilograms, having an excellent load-to-weight ratio, and supporting more than 20 interaction gestures. The unique rigid-flexible combination structure enables the dexterous hand to achieve a perfect balance between high load and flexibility, reducing costs by 90%.
In addition to the dexterous hand, what other innovative breakthroughs does GoMate have in hardware?
The robot research and development team of GAC Group has built a low-cost and high-performance system platform architecture to enable GoMate to meet users’ dual needs for high performance and low cost. GoMate has achieved independent research and development of drivers, motors, and integrated joint modules. The driver has rich interfaces, is small in size and high in power, with a maximum continuous current of up to 50A and a space reduction of 80%. The axial flux motor has a maximum output torque of up to 800N·m and a torque density of up to 200N·m/kg, with an overload multiple of more than 5 times. The module height is 15% lower than that of competing products of the same specification. The integrated joint module with drive-control integration design provides two structural options of single and double encoders, realizing a highly integrated and miniaturized execution system. It weighs only 300 grams and can output a rated torque of 10N·m, and the temperature rise is controlled below 55℃.
How is GAC’s autonomous driving technology applied to humanoid robots? What are the essential differences between autonomous driving cars and humanoid robots?
The application of GAC’s autonomous driving technology on GoMate is reflected in two aspects: sensor configuration and technical route. In terms of sensor configuration, GAC Group has an innate advantage in cost control of humanoid robots. In terms of technical route, the traditional perception-decision-control route and end-to-end technical route are applied to humanoid robots, and significant progress has been made in sensor solutions based on lidar. The difference between autonomous driving cars and humanoid robots lies in practical application differences. Autonomous driving cars have relatively simple control dimensions and easy data collection, but have extremely high requirements for functional safety. Humanoid robots have greater technical difficulties, and data collection and skill generalization are difficult, but they have advantages in safety and have more potential in certain application scenarios.
