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 can move independently is called the degree of freedom of the robot, or simply the degree of freedom. Usually, the degree of freedom is a technical indicator of a robot that reflects the flexibility of the robot's movements and can be expressed by the number of linear movements, swings, or rotations of the axis.

Industrial robots How many degrees of freedom do they have?

Industrial robots generally have 4 or 6 degrees of freedom. Articulated robots are mainly designed to imitate human arms. So the degree of freedom of an articulated robot refers to the number of axes driven by several motors. The higher the degree of freedom, the higher the flexibility. There are also 1, 2, 3, 5, etc., mainly based on the work content and scope, to design different degrees of freedom to meet the requirements.

Although the flexibility of the robot increases with the increase in the number of axes, that is, the degrees of freedom, but in current industrial applications, the most commonly used are three-axis, four-axis, five-axis dual-arm and six-axis industrial robots. The choice of the number of axes usually depends on the specific application.

The control method currently used by industrial robots is to treat each joint on the robot arm as a separate servo mechanism, that is, each axis corresponds to a servo, and each servo is controlled by the bus and uniformly 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 an industrial robot is its important technical indicator.
