Most of the robotic arms are single arms, and they are only applicable to the factory's standardized product line. The aging of the population has prompted more and more people to need robot care. In this non-standardized and real-time changing application scenario, designing a cloud-based intelligent dual-arm service robot can provide better services for people.Simple and friendly, the round and soft shape can reduce the user's feeling of coldness and alienation towards mechanical products. The application of carbon fiber tubes can increase the strength of the product, reduce the weight of the whole machine, and enhance the professionalism of the product.The robot consists of two mechanical arms with 6 degrees of freedom, embedded with 14 SCA2.0 actuators, the up and down grasping range can reach 2 meters, the maximum horizontal grasping distance is 750mm, and the end load is 3kg. The large-stroke lifting and rotating mechanism is equipped with a standard 1.5-meter lifting space, which can meet the practical needs of most space scenarios. The arm span can be customized between 600mm and 900mm, which is very flexible.
