Product Detail
High rigidity low inertia small envelope：Through the optimization of the robot arm topology, the high rigidity and low inertia arm body is realized. The horizontal cabling method greatly reduces the space of the robot envelope and facilitates the customer system layout and use.
Beautiful shape：Robot body with a screw-free design concept, with beautiful streamlined shape, shaping the industrial works of art.
Selection covers a wide range：400mm and 600mm wingspan two flagship product, and can choose 300mm, 500mm, 700mm range, support customization.
