Mechanical arm motion visualization method and system, terminal equipment and readable storage medium

The invention relates to the technical field of mechanical arms, and discloses a mechanical arm motion visualization method and system, terminal equipment and a readable storage medium. According to the method, the target position, expected to reach, of the tail end of a mechanical arm input by a user in an interaction interface is received; obtaining a reachable area of the tail end of the mechanical arm to detect whether the target position is valid or not; when the target position input by the user is valid, the tail end of the mechanical arm is controlled to move from the current position to the target position, joint related connecting points and the tail end position corresponding to the respective motion planes are selected as key points, the motion state of the tail end is visually displayed, and the target position input by the user is effectively detected; the situation that normal movement of the mechanical arm cannot be controlled due to the fact that an unreachable target position is input can be
