The smart robot arm is one of the core components in the field of construction robots, which is used to perform the functions of the execution end. It has excellent mechanical properties, equipped with integrated sensors, and has a payload of up to 25KG. It uses 6 groups of unit types to form the main body of the seven-axis robotic arm, and the detailed design of the diamond shape enhances the structural stability. The robotic arm realizes real-time motion control through sensor information such as machine vision and force sensing, and intelligent closed-loop control to the end of the tool, so that it can achieve complex applications that cannot be achieved by traditional industrial robots and has powerful application interaction capabilities, forming multiple coordination capabilities with humans, machines, and the environment.
