The details of how the unknown subsystems of the stock PHANToM can be replaced with known, high-performance systems and how additional measurement electronics can be interfaced to compensate for some of the PHAN toM's shortcomings are presented.
Abstract
This paper presents a critical study of the mechanical and electrical properties of the PHANToM haptic interface and improvements to overcome its limitations for applications requiring high-performance control. Target applications share the common requirements of low-noise/granularity/latency measurements, an accurate system model, high bandwidth, the need for an open architecture, and the ability to operate for long periods without interruption while exerting significant forces. To satisfy these requirements, the kinematics, dynamics, high-frequency dynamic response, and velocity estimation of the PHANToM system are studied. Furthermore, this paper presents the details of how the unknown subsystems of the stock PHANToM can be replaced with known, high-performance systems and how additional measurement electronics can be interfaced to compensate for some of the PHANToM's shortcomings. With these modifications, it is possible to increase the maximum achievable virtual wall stiffness by 35%, active viscous damping by 120%, and teleoperation loop gain by 50% over the original system. With the modified system, it is also possible to maintain higher forces for longer periods without causing motor overheating.

Haptic guidance: experimental evaluation of a haptic training method for a perceptual motor skill

TL;DR: While visual training was better for teaching the trajectory shape, temporal aspects of the task were more effectively learned from haptic guidance, suggesting a possible role for haptics in the training of perceptual motor skills in virtual environments.

A robotic indenter for minimally invasive measurement and characterization of soft tissue response.

TL;DR: An inverse finite element solution was developed using ANSYS finite element package to estimate the optimum values of viscoelastic and nonlinear hyperelastic material properties of pig liver through iterations and the initial estimates of the material properties for the iterations were extracted from the experimental data for faster convergence of the solutions.

Creating Realistic Virtual Textures from Contact Acceleration Data

TL;DR: This paper employs a sensorized handheld tool to capture the feel of a given texture, reduces the three-dimensional acceleration signals to a perceptually equivalent one-dimensional signal, and uses linear predictive coding to distill this raw haptic information into a database of frequency-domain texture models.

The Benefit of Force Feedback in Surgery: Examination of Blunt Dissection

TL;DR: It is hypothesized that force feedback is helpful in this blunt dissection task because the artery is stiffer than the surrounding tissue, which serves to constrain the subject's hand from commanding inappropriate motions that generate large forces.

Intelligent Control Algorithms for Robotic-Assisted Beating Heart Surgery

TL;DR: Here, a model-based intelligent ARMC algorithm employing biological signals, such as electrocardiogram, to achieve effective motion cancellation is proposed and experimental results of the algorithm on a 3-degree-of-freedom robotic test-bed system are reported.
