Abstract
A force/tactile feedback device feeding back a force sense to a fingertip of an operator includes a fingerstall to which the fingertip of the operator is inserted, a position feedback means for feeding back a position to the fingertip held by the fingerstall, a fingertip contact point feedback means for feeding back a fingertip contact point to the fingertip held by the fingerstall and an unnecessary moment removal means for supporting the fingertip contact point feedback means so that unnecessary moment is not generated at a tip portion of the position feedback means.
Claims14
A force/tactile feedback device feeding back a force sense to a finger, including a fingertip, of an operator comprising:
- a fingerstall into which the fingertip of the operator is inserted;
- a position feedback means for feeding back a position to the fingertip held by the fingerstall;
- a fingertip contact point feedback means for feeding back a fingertip contact point to the fingertip held by the fingerstall, wherein the fingertip contact point feedback means is configured to move the fingertip contact point along the fingertip held by the fingerstall;
- and
- an unnecessary moment removal means for supporting the fingertip contact point feedback means so as to limit generation of unnecessary moment at a tip portion of the position feedback means.
A force/tactile feedback device feeding back a force sense to a finger, including a fingertip, of an operator comprising:
- a 3 degree-of-freedom arm for position feedback;
- a 3 degree-of-freedom gimbal mechanism;
- a more than one degree-of-freedom fingertip portion holding mechanism into which the fingertip of the operator is inserted;
- a 1 degree-of-freedom arm for feeding back a fingertip contact point to the fingertip held by the fingertip portion holding mechanism, wherein the one degree-of-freedom arm is configured to move the fingertip contact point along the fingertip held by the fingertip portion holding mechanism.
A force/tactile feedback device feeding back a force sense to a finger, including a fingertip, of an operator comprising:
- a fingerstall into which the fingertip of the operator is inserted;
- a position feedback unit configured to feed back a position to the fingertip held by the fingerstall;
- a fingertip contact point feedback unit configured to feed back the fingertip contact point to the fingertip held by the fingerstall, wherein the fingertip contact point feedback unit is configured to move the fingertip contact point along the fingertip held by the fingerstall;
- and
- an unnecessary moment removal unit configured to support the fingertip contact point feedback unit so as to limit generation of unnecessary at a tip portion of the position feedback unit.
