Abstract: Provided is a tele-operated forceps-driver variable stiffness master device including a master member to generate an input displacement signal generated by pressing with a user's finger, and a slave member to operate based on the input displacement signal, measure operation information, calculate a gripping force based on the operation information, and provide the master member with at least one of a stiffness change command signal or a force feedback based on the calculated gripping force.
