What are the degrees of freedom of industrial robots? How many degrees of freedom do industrial robots have?
What is the degree of freedom of a robot? Generally speaking, the number of joints that the robot mechanism can move independently is called the degree of freedom of the robot mechanism. Usually, as the technical index of robot, the degree of freedom can reflect the flexibility of robot action, which can be expressed by the number of linear movement, swing or rotation of the axis.
How many degrees of freedom do industrial robots have?
The degree of freedom of industrial robot is generally divided into 4 degrees of freedom, or 6 degrees of freedom. The joint robot is mainly designed by imitating the human arm. So the degree of freedom of the joint robot refers to several axes driven by several motors. The higher the degree of freedom, the higher the flexibility. There are also one, or two, three, five, and so on. It is mainly to design different degrees of freedom according to the work content and work scope to meet the requirements.
Although the flexibility of the robot increases with the increase of the number of axes, that is, the degree of freedom, but in the current industrial applications, the industrial robots with three axes, four axes, five axes, two arms and six axes are used more, and the selection of the number of axes usually depends on the specific application.
At present, the control method used by industrial robots is to treat each joint on the manipulator as a separate servo mechanism, that is, each axis corresponds to a server, and each server is controlled by the bus, which is controlled and coordinated by the controller. In industrial automation applications, the base of the robot can be fixed or movable. It can be seen that the number of axes of industrial robots is an important technical index.
