What is the function of an excursion amplifier?

The function of an excursion amplifier is to enhance the motion range of an actuator or similar device, effectively doubling the excursion or the distance the device can move. This mechanism achieves an increase in motion range but simultaneously requires the application of double the force to achieve this enhanced movement. This characteristic makes the excursion amplifier particularly useful in situations where a broader range of motion is needed, despite the increased demand for force. Such amplifiers can be crucial in applications like robotics or prosthetics, where the extent of movement is a key factor in overall performance and functionality.
