Design and Workspace Analysis of Drilling Arm of Mining Anchor Drilling Robot

Abstract Bolt support is the main way of underground roadway in coal mines China. At present, there are some problems domestic mines, such as low efficiency and poor safety. In view above problems, a structural scheme omni-directional multi angle automatic roof bolter designed. Firstly, based on D-H method, kinematics model drill arm structure anchor drilling robot to side working environment established, space analysis four arms carried out; same time, due design robot, left right equipment extend, rotate work at time. Combined with MATLAB model, experiment out simulate spatial position end robot. research results show that can quickly replace ensure quality all-round drilling, meet requirements support.
