This paper analyzes the advantages and disadvantages of Cartesian space trajectory planning and joint space trajectory planning. To achieve the balance between efficiency and accuracy of trajectory planning, an excavation trajectory planning method based on path coarse interpolation is proposed. Firstly, a kinematic model of the excavator is established, and the excavation path is determined. Then, the excavation path is coarse interpolated in Cartesian space and divided into multiple excavation key points. Finally, the trajectory planning is carried out in the joint space. Taking space line and space arc as examples for simulation analysis, the simulation results show that the actual path under this method coincides with the planned path highly, and the maximum error and average error in X and Z direction are both less than 0.01mm, which ensures the accuracy of path execution and has small amount of calculation. This method achieves a balance between trajectory planning efficiency and accuracy.
