Brief introduction： A roadheader, also called a boom-type roadheader, road header machine or road header. It is a piece of excavating equipment consisting of a boom-mounted cutting head, a loading device which usually involving a conveyor and a crawler travelling track which move the entire machine forward into the rock face.

Based on the Denavit–Hartenberg (D–H) convention (Craig, 2006), the link constants are a 1, a 2, and d 2, the joint variables are θ 2, θ 3 and d 3.
the roadheader was removed from the site and drill and blast tunneling was used instead. The special problems of drilling performance and its influence on the working cycle are discussed in Thuro 1997 b. Fig. 3: Typical asymmetric wear (type 3 ð Table 2) of the outer cutter head bits of the used 300 kW roadheader.
In this research, the D-H method was used to solve forward kinematics problem, which was the precise positioning of cutting head spatial pose; and an algebraic method was used to analyze inverse kinematics problem, which was the mathematical model of cutting head trajectory planning and control.
