ACTUATORS FOR PROVIDING MULTIDIRECTIONAL KINESTHETIC EFFECTS

Abstract:

Multi-directional kinesthetic actuation systems are provided. The multi-directional kinesthetic actuation systems are configured to provide kinesthetic effects in multiple directions through both pulling and pushing forces. Multi-directional kinesthetic actuation systems include at least an active linkage, one or more hinges, and a motor. The motor is employed to advance or retract the active linkage. The active linkage is activated to provide increased buckling strength to transfer force to the hinges and deactivated to increase flexibility to facilitate retraction by the motor. The hinges are configured to translate the pushing or pulling force provided by the active linkage into a torque to be provided to a user's finger.
