Abstract：This paper prest3nts a new model of the force sensing telepresence system,discusses its two-portnetwork structure,deduces relevant hybrid matrix of the network,and analyses the meaning and measuringmethod of the parameters.Besides,the hyhrid matrix of the ideal system are also given,The research of thepaper lays the foundation for the development of the telepresence technology.
