Because of the use of scattering based communication channels, passivity based telemanipulation systems can be subject to a steady state position error between master and slave robots. In this paper, we consider the case in which the passive master and slave sides communicate through a packet switched communication channel (e.g. Internet) and we provide a modification of the slave impedance con...

In this paper two problems arising in the digital passive scheme for telemanipulation presented in [5] are addressed. At first, we show how to preserve system passivity in presence of quantization error introduced by position sensor (i.e. encoders) by introducing energy dissipation. Then, we introduce a scheme for a redundant communication channel that will compensate for missed packets improvi...

We present a retinal-surgery telemanipulation system with submicron precision that is compact enough to be head-mounted and that uses a full range of existing disposable instruments. Two actuation mechanisms are described that enable the use of actuated instruments, and an instrument adapter enables quick-change of instruments. Experiments on a phantom eye show that telemanipulated surgery resu...

Abstract Minimally invasive surgery (MIS) has been an essential tool in the surgical sector for many years due to its crucial advantages compared open surgery. To overcome remaining limitations, teleoperated MIS experienced a strong emergence. However, widespread usage of such systems is hindered by enormous financial hurdle. The use standard components and conventional tools can facilitate int...

A virtual transducer forming technique has been developed with an objective to enhance remote environment perception in tele-robotic systems by adding proximity feel in pre-contact phase during remote manipulation tasks. A fluidics inspired transducer model has been conceived and designed to serve for master side perception creation based on remote robot’s proximity with workspace objects and i...

Robots are used for the purpose of picking the object and placing it into another place. This robot runs with human guidance and communicates through blue tooth. The robot setup is controlled by the android mobile which is having the blue-control application. Tele-manipulation allows human to perform operations in a remote environment. This system provides human operators with the ability to se...
