Abstract
A force sense generator includes a rotatable circular plate having a rotation axis at a center of gravity; a motor that drives the circular plate to be rotated; a cam formed at a surface of the circular plate so as to surround the rotation axis; an anchor that is reciprocated along a linear trajectory that is perpendicular to the rotation axis of the circular plate; and a follower provided at the anchor and is moved along the cam, the cam being configured to include a first angle range and a second angle range such that the anchor is moved in opposite directions at different accelerations when the follower moves within the first angle range and when the follower moves within the second angle range, respectively, while the circular plate is rotated in one direction.
