In order to reduce the energy consumption of the welding robot and ensure the cooperative movement of the robot joints. a trajectory planning method with optimal energy consumption based on improved sparrow search algorithm is proposed. Firstly. the trajectory planning model with optimal energy consumption is established based on the joint torque and angular velocity of the robot. https://www.roneverhart.com/Apple-Watch-Series-6-GPS-Cellular-40mm-Silver-Aluminum-w-White-Sport-Band/
