Robotic end effector is a quick-change mobile robotic system that can deploy tools. They are also known as robotic accessories, robotic peripherals and robotic tools. A robotic end effecter is an object, which when connected to a robot flange, such as a wrist, serves the desired functions of the wrist. It can function as robotic collision sensors, robotic arc welding guns, robotic deburring tools, robotic rotary joints, robotic press tooling, or robotic tool changers. It operates as robotic welders, which can be articulating robots or rectilinear robots. Robotic end effectors are provided with flexibility to automatically change the peripherals by the use of robotic tool changer and find various applications such as various welding processes.
