As a new generation of industrial-grade interactive body-work robot, it inherits the ecological advantages of G1, and its functions and parameters are fully upgraded. It can be called a "hexagonal soldier" in the robot industry ". The G2 waist adopts a 3-degree-of-freedom design, which can realize human-like movements of bending, rotating waist and swinging sideways. It is equipped with the world's first cross wrist force control arm, and the whole arm is equipped with a high-precision joint torque sensor. It realizes delicate external force sensing and compliant response through joint impedance control. With a rapid deployment tool chain, ordinary users can easily get started without force control and parameter adjustment experience. In terms of endurance, G2 supports autonomous recharging and dual-battery hot-plug power exchange, which can meet the 24-hour continuous operation requirements of the factory production line.
