24 Mar 2002TL;DR: The Rutgers Master II-ND glove is a follow up on the earlier RutgersMaster II haptic interface and has all the sensing placed on palm support, avoiding routing wires to the fingertips.
Abstract: The Rutgers Master II-ND glove is a follow up on the earlier Rutgers Master II haptic interface. The redesigned glove has all the sensing placed on palm support, avoiding routing wires to the fingertips. It uses custom pneumatic actuators arranged in a direct-drive configuration between the palm and the thumb, index middle and ring fingers. The supporting glove used in the RMII design is eliminated, thus the RMII-ND can better accommodate varying hand sizes. The glove is connected to a haptic control interface that reads its sensors and servos its actuators. The interface pneumatic pulse-width modulated servo-valves have higher bandwidth than those used in the earlier RMII, resulting in better force control. A comparison with the CyberGrasp commercial haptic glove is provided.

TL;DR: The results to the design of haptic interfaces for teleoperation and virtual environments, which share some of the same reduction of sensory cues that the experimentally produced results share, are related.
Abstract: In the present article, we will consider how well people can haptically identify common objects when manual exploration is constrained. The constraints imposed in this study were produced by imposing a rigid link between the skin and the object, in the form of a sheath over the finger or a probe held in the hand. Any constraint that forms an intermediate barrier between skin and objects can be described as producing remote (or indirect) perception. Such intermediaries serve to constrain haptic exploration by reducing the cutaneous and/or kinesthetic inputs available. In earlier work (Klatzky, Loomis, Lederman, Wake, & Fujita, 1993), manual exploration has been constrained in several other ways that did not involve using a rigid link. In this article, we integrate the results of the earlier Klatzky et al. (1993) study with those of the present study to further our understanding of haptic object identification by direct and remote touch. In addition, we relate the result to the design of haptic interfaces for teleoperation and virtual environments, which share some of the same cue reductions that we have produced experimentally. Our article arises from two separate but related themes in previous research on haptic perception.

TL;DR: A novel robotic end‐effector is described that meets the requirements of endoscopic surgery and is sensorized for force/ torque feedback and can be used as the last arm of a surgical robot to incorporate haptic feedback and/or to evaluate skills and learning curves of residents and surgeons in endoscopic Surgery.
Abstract: Conventional endoscopic surgery has some drawbacks that can be addressed by using robots. The robotic systems used for surgery are still in their infancy. A major deficiency is the lack of haptic feedback to the surgeon. In this paper, the benefits of haptic feedback in robot-assisted surgery are discussed. A novel robotic end-effector is then described that meets the requirements of endoscopic surgery and is sensorized for force/ torque feedback. The endoscopic end-effector is capable of non-invasively measuring its interaction with tissue in all the degrees of freedom available during endoscopic manipulation. It is also capable of remotely actuating a tip and measuring its interaction with the environment without using any sensors on the jaws. The sensorized end-effector can be used as the last arm of a surgical robot to incorporate haptic feedback and/or to evaluate skills and learning curves of residents and surgeons in endoscopic surgery.

TL;DR: A variety of sensory and perceptual consequences of eliminating, via a rigid fingertip sheath, the spatially distributed fingertip force information that is normally available during tactile and haptic sensing are reported.
Abstract: This article reports a variety of sensory and perceptual consequences of eliminating, via a rigid fingertip sheath, the spatially distributed fingertip force information that is normally available during tactile and haptic sensing. Sensory measures included tactile spatial acuity, tactile force, and vibrotactile thresholds. Suprathreshold tasks included perception of roughness, perception of 2-D edge orientation, and detection of a simulated 3-D mass in simulated tissue via fingertip palpation. Of these performance measures, only vibrotactile thresholds and texture perception failed to show substantial impairment. The results are discussed in terms of their implications for the future design of haptic interfaces for teleoperator and virtual environment systems.
