Abstract
A remote control system and a remote control method of a construction machine for reducing a fatigue degree of an operator at the time when the operator controls driving of the construction machine depending on his/her body motion in the remote control system of the construction machine. For this, according to the present disclosure, a value acquired by compensating for a predetermined value εwith respect to a finger bending angle βfor a palm is tracked by a bending angle βof a bucket at the time of tracking the position of the bucket depending on hand motion of the operator to reduce a finger bending movement amount of the operator, thereby reducing fatigue. Further, the workspace of the operator is set to be smaller than points which are maximally movable in each of X, Y, and Z-axis directions at the time of setting the workspace of the operator, the workspace of WSof the operator set to be small and a machine workspace WSmatch each other, and the operator performs an operation in the workspace which is set to be small, thereby reducing the fatigue.
