Degrees of Freedom in Robotic Joints

Te koncept of degrees of freedem (DOF) is fundamentaltal to understaning robotic joint capabilities. Degree of Freedom refers to te number of decreent movements a joint can perfom. A robotic arm with six desers of freedem can nawigate three- dimensional space, enabling tasks such as precisision assembly, welding, and even microecolovics handling with submilieter contriacy.
