| 英文摘要 | A method to solve the problem of configuration selection of super-redundant serial manipulators based on the workspace analysis is proposed. The Monte Carlo method for the robot workspace is improved using normal distribution. The normalized maneuverability index is used to analyze the flexibility of the manipulator's movement. The relationship between the maximum manipulability value and the number of random joint angle combinations is obtained by numerical simulation, and an algorithm to obtain a flexible workspace is proposed. Based on the obtained workspace, a voxelization algorithm is proposed to obtain the volume of the workspace, and the boundary and non-boundary parts of the workspace are found. Through the refinement of the boundary part, the volumetric error is reduced. A multivariant serials manipulator configuration design method is analyzed. For the nine-degree-of-freedom super-redundant series manipulator, 36 kinds of configuration schemes to be selected are determined. The workspace of the nine-degree-of-freedom super-redundant series manipulator is simulated and analyzed, and a set of optimal configurations is selected in the candidate configuration. The results show that the improved Monte Carlo method generates accurate workspace; the volume extraction algorithm has high efficiency and the relative error is less than 1%; the workspace index of the selected configuration is better than the configuration developed by this research group. Reachable workspace volume increases by 26.49% and flexible workspace volume increases by 36.63%. 2019 Journal of Mechanical Engineering. |
