The invention discloses a remote operation method of a distribution network live working robot and a construction method of a motion track library for the distribution network live working robot. Theconstruction method of the motion track library comprises the following steps: 21, acquiring a standard action of an operator during live line work maintenance of a distribution network through a three-dimensional motion capture system; 22, calculating joint angles of a shoulder joint motor, an elbow joint motor and a wrist joint motor by analyzing and extracting motion tracks of mark points on arms of the operator; 23, using the double-arm robot to reproduce the motion of the arms of the operator, and acquiring motion tracks of mechanical arms through the three-dimensional motion capture system; 24, optimizing the motion tracks of the mechanical arms according to the completion effects of the tasks of the same type; 25, parameterizing the optimized motion tracks of the mechanical arms toform basic motion tracks; and 26, repeatedly executing the step 21 to the step 25, and establishing the basic motion track library of the distribution network live working robot. The remote operationmethod of the distribution network live working robot aims to solve the problems of low efficiency and multiple accidents caused by excessive fatigue of the operator in remote operation, and further achieve autonomous operation to a certain degree.
