WebbThe transformation matrix can be determined by successively rotating and translating coordinate frame k-1 to render it coincident with coordinate frame k. The four steps are: Rotate Lk-1 about zk-1 by ; this makes axis xk-1 parallel to axis xk. Translate Lk-1 along zk-1 by dk; this makes axis xk-1 collinear with axis xk.
