The main functions of industrial robot control include precise positioning, trajectory planning, speed control, and switching between multiple operating modes. The provided six-joint industrial robots possess high-speed motion capabilities, such as speeds up to 9 m/s, Z-axis speeds of 0-3 m/s, and Y-axis speeds of 0-9 m/s. They also boast high-precision repeatability (handling) of 0.1-5 mm and a wide working range of 750-2000 mm. Their control method utilizes numerical control (CNC), enabling flexible handling of various metal objects and supporting multiple welding methods such as argon arc welding, gas shielded welding, and laser welding. These robotic arms effectively meet these control requirements.
In industrial robot systems, software plays a crucial role. The software mentioned here specifically refers to the robot's control software, which encompasses motion trajectory planning algorithms, joint servo control algorithms, and corresponding motion programs. Control software can be written using various programming languages; however, the current mainstream trend in industrial robot control software is to use general-purpose languages for modular programming, thus forming dedicated industrial languages designed specifically for industrial applications.
A robot's control system is a complex system involving kinematics and dynamics principles, characterized by multivariables, coupling, and nonlinearity. Due to its unique nature, classical and modern control theories cannot be directly applied. Currently, robot control theory is still under continuous improvement and development.
