Teleoperation systems are used when human planning and decision-making capabilities are needed during robotic remote operations. To execute meaningful tasks remotely, the operator has to be able to simultaneously control multiple degrees of freedom (DoFs) of the slave robot and efficiently receive information from the remote site. In these cases, haptic(More)
In part 1 of the current study of haptic displays, a finite element (FE) model of a finger exploring a plate vibrating out-of-plane at ultrasonic frequencies was developed as well as a spring-frictional slider model. It was concluded that the reduction in friction induced by the vibrations could be ascribed to ratchet mechanism as a result of intermittent(More)
