Abstract
In this paper, we firstly develop the system which connects an end-effector with wire just before launching the end-effector. We then conduct the experiment and verify the stable connection by six trials. We secondly propose the method to decelerate the flight speed of the end-effector after launching it. The spring is used for smooth deceleration and the ratchet is used for prevent the expanded spring from restoring. We develop the ratchet-reel system and confirm that it decelerates the translational speed of the end-effector as well as its rotational speed through experiments.
