A force-feedback device comprising a first member; a first kinematics bond being coupled with said first member; said first kinematics bond being constructed to provide at least one degree of freedom for movements of said first member; said first kinematics bond comprising a braking device being constructed to constrain movements of the said first member in at least one of said at least one degree of freedom; and a energy storing/release device being constructed to store energy in response to a movement of said first member in at least one of said at least one degree of freedom constrained by said braking device. A method of providing force-feedback including constraining a movement of a member of a haptic device in at least one degree of freedom; moving the member, by an externally applied force, in at least one of the at least one constraint degree of freedom; storing energy generated by the moving of the member; determining a force required to move the member in at least one of the at least one constraint degree of freedom; releasing at least a portion of the stored energy to generate at least a portion of the required force and transmitting the at least a portion of the required force to the member.

Force-feedback device and method

A device for transmitting movements comprising a parallel kinematics transmission structure adapted to provide at least one degree of freedom including three translational degrees of freedom, the parallel kinematics transmission structure further comprising a base member (), a moveable member (), and at least one parallel kinematics chain () coupling the base member () and the moveable member (), each parallel kinematics chain () having a first arm () moveable in a movement plane wherein the movement planes are at a distance to a symmetry axis (), and each parallel kinematics chain () comprising a second arm () coupled to the moveable member (), wherein a first end () of the second arm () is adapted to be coupled to the first arm () and a second end () of the second arm () is adapted to be coupled to the moveable member ().
