Footprint generator capable of applying constant force and footprint generation method using the same

A footprint generator capable of applying a constant force, the footprint generator comprising:

• a base plate in which a target surface is on an upper surface of the base plate;
• a shoe mounting member that is apart from the upper surface of the base plate and capable of mounting a shoe;
• a driving unit that is apart from the upper surface of the base plate and capable of moving the shoe mounting member up and down;
• a fixing unit configured to be directly connected to the base plate and fix the shoe mounting member and the driving unit in a position apart from the upper surface of the base plate;
• a force measuring unit configured to measure an impact force when the shoe mounting member descends and contacts the shoe with the target surface to generate a footprint on the target surface;
• an input unit configured to receive an input signal according to a user input;
• a control unit configured to operate the driving unit according to the user input to control the shoe mounting member on which the shoe is mounted to descend and generate the footprint on the target surface by an impact;
• and
• a display unit configured to display user input information capable of operating the driving unit with a constant force or operation information of the driving unit,
• wherein the driving unit is formed in a shape rotatable about a horizontal axis, and is capable of rotating the shoe mounting member at a certain angle or more about the horizontal axis of the driving unit,
• wherein the shoe mounting member comprises:
• a shoe fixing unit capable of fixing the shoe and adjustable based on length of the shoe;
• and a connecting unit formed to connect the driving unit to the shoe fixing unit to rotate the shoe fixing unit about the horizontal axis of the driving unit, and
• wherein the user input information comprises:
• the amount of force applied to the target surface, number of times the driving unit is operated, or an angle at which the shoe mounting member rotates about the horizontal axis of the driving unit.
