Towards a discretely actuated steerable cannula

Towards a discretely actuated steerable cannula

IEEE International Conference on robotics and automation (ICRA)

作者： Elif Ayvali Jaydev P. Desai Robotics Automation and Medical Systems (RAMS) Laboratory Maryland Robotics Center Institute for Systems Research Department of Mechanical Engineering University of Maryland College Park MD USA

Several percutaneous needle-based and intravascular procedures require guidance of the diagnostic or therapeutic tool to the target location by maneuvering the needle or catheter to correct for the error in reaching the target location. Hence, in this paper we present our work towards developing a discretely actuated steerable needle/cannula with multiple degrees-of-freedom to `steer' the cannula by discrete actuation along the cannula length. We are interested in using the cannula to introduce both diagnostic and therapeutic tools, which may otherwise be difficult to deliver to the appropriate location. We use two antagonistic SMA wires as actuators to generate the required bending forces at each joint. SMA wires were annealed through a customized training process to an arc shape and mounted in the machined grooves on the outer surface of the cannula to generate local bending upon thermal actuation. We propose to use temperature feedback to control the position of the SMA actuators. To use temperature feedback as the feedback signal for enabling individual joint actuation, we had to fully characterize the SMA actuator. Classical uniaxial testing devices and experimental setup used in characterizing straight annealed SMA wires are not applicable in this work since the SMA wire is annealed in an arbitrary shape. Hence, we also present an experimental setup and a procedure for characterizing an SMA actuator that transforms into an arc shape upon thermal actuation.

IEEE International Conference on robotics and automation (ICRA)

In this paper, we present the design and development of a magnetic resonance imaging (MRI)-compatible tendon-driven robot to overcome the limitations of our previous minimally invasive neurosurgical intracranaial robot (MINIR). In this prototype, the robot is made of plastic and the MRI-compatible shape memory alloy (SMA) actuators are placed away from the robot. The robot has four revolute joints which are placed orthogonally to have out-of-plane motion capability. Each joint is connected to a pair of antagonistic SMA spring actuators through the tendon-sheath mechanism. Each SMA spring actuator can be controlled independently to actuate the corresponding joint. A theoretical model and experimental setup have been developed to evaluate the recovery force of the SMA spring at different displacement and temperatures. The experimental results closely match the theoretical model and it shows significant promise for future development in this area. A series of MRI compatibility tests have also been performed to evaluate the MRI compatibility of the device and to assess the degradation in image quality, if any, during actuation. The experimental results clearly demonstrate that the robot is MRI-compatible and it creates no significant distortion in the MR images during actuation.

This paper explores the relationship between the structure of a network of agents and how efficiently they can learn a common unknown parameter. Agents repeatedly make private observations which are possibly informative about the unknown parameter; they also communicate their beliefs over the set of conceivable parameter values to their neighbors. It has been shown that for agents to learn the realized state, it is sufficient that they incorporate in their beliefs their private observations in a Bayesian way and the beliefs of their neighbors using a fixed linear rule. In this paper we establish upper and lower bounds on the rate by which agents performing such an update learn the realized state and show that the bounds can be tight. These bounds enable us to compare efficiency of different networks in aggregating dispersed information. Our analysis yields an important insight: for agents in large balanced networks learning is much slower compared to that of a central observer regardless of the distribution of information in the network, whereas unbalanced networks result in near efficient learning if the observations of the centrally positioned agents are much more informative than others' observations.

In this paper a pattern classification and object recognition approach based on bio-inspired techniques is presented. It exploits the Hierarchical Temporal Memory (HTM) topology, which imitates human neocortex for recognition and categorization tasks. The HTM comprises a hierarchical tree structure that exploits enhanced spatiotemporal modules to memorize objects appearing in various orientations. In accordance with HTM's biological inspiration, human vision mechanisms can be used to preprocess the input images. Therefore, the input images undergo a saliency computation step, revealing the plausible information of the scene, where a human might fixate. The adoption of the saliency detection module releases the HTM network from memorizing redundant information and augments the classification accuracy. The efficiency of the proposed framework has been experimentally evaluated in the ETH-80 dataset, and the classification accuracy has been found to be greater than other HTM systems. © 2012 IEEE.

Contact mode Atomic Force Microscopy (AFM) is popularly used by the biophysics community to study mechanical properties of cells and tissue due to its ability to quantify biological processes like disease proliferation and stem cell differentiation. While AFM indentation experiments are relatively straightforward, interpretation of the AFM data is subject to some debate. Three factors make the AFM force data prone to incorrect interpretation, namely, the appropriate contact model to use to fit the post-contact AFM data, identifying the point when the AFM probe contacts the cell, and variability in the stiffness of the probe used to estimate material properties of cells. A lot of research has been directed towards developing constitutive models based on sample material property assumptions, however, variability in the AFM probe stiffness and contact point uncertainty has received limited attention. This suggests the need to have an integrated probabilistic model to estimate mechanical properties from the AFM force data which can account for errors contributed from these two sources. In this work, we have developed an Error-In-Variables (EIV) based Bayesian Changepoint model to estimate the contact point and the Young's Modulus from AFM force curves on fixed mouse Embryonic Stem cells (mESC) in the indentation range of 1-1.5 μm. Our results indicate that the EIV-based Bayesian Approach can be used to obtain robust estimates of material properties of biomaterials.

Modern myoelectric hand prostheses continue to increase in functionality, while their control is constrained by the limits of myoelectric input. This paper covers the development and testing of grasp control systems for multifunctional myoelectric prosthetic hands. The functionality of modern hand prostheses is often focused on the task of grasping, which can be divided into high-level grasp planning and low-level finger control. Initially, models can used to test these control systems, but for proper evaluation actual implementation on a physical system is required. The University of Bologna (UB) Hand IV prototype is an anthropomorphic, tendon-driven robotic hand, which makes it well-suited to represent the structure of modern prostheses. One of the main control systems tested in this paper is based on the intrinsically passive controller (IPC), the structure of which offers guaranteed passivity and stability. After several grasping tests, the systems are evaluated on compliant behavior, grasping ability, and dynamic appearance. IPC proves to be a powerful approach to interaction control, without the associated sensor requirements which could be difficult to meet in modern hand prostheses.

Inducing self-rotation of Melan-a cells by ODEP

This paper presents our discovery that self-rotation of Melan-a pigment cells can be induced by applying appropriate optical dielectrophoretic (ODEP) parameters. Under optically induced DEP force, which is generated by specific optical electrode patterns and with a band-width of AC bias frequencies, Melan-a cells can be trapped or repelled away from the optical electrodes. In addition, the self-rotation motion of the Melan-a cells was observed. In particular, the applied frequency and voltage dominate the overall cell motion. Hence, the cells can be manipulated on an electrode-free surface. This project studies the rotation and translation motions of the cells in an ODEP system. We speculate that the unbalanced distribution of melanin inside the pigment cells causes this self-rotation phenomenon. Therefore, both pigment cells (Melan-a) and non-pigment cells (Raw 264.7) have been tested in the ODEP experiments to compare their motion behavior. Potential applications for this novel observation are to use the self-rotation phenomenon to elucidate the pigment cells' physical property, and separate the pigment and non-pigment cells. © 2012 IEEE.

We analyze a model of social learning in which agents desire to identify an unknown state of the world using both their private observations and information they obtain when communicating with agents in their social neighborhood. Every agent holds a belief that represents her opinion on how likely it is for each of several possible states to be the true one. At each time period, agents receive private signals, and also observe the beliefs of their neighbors in a social network. They then update their beliefs by integrating the information available to them in a boundedly rational fashion. We show that in spite of agents' making new private observations perpetually and the myopic and local updating rule employed by them, agents will eventually reach consensus in their beliefs. This is proved by first showing that agents' beliefs over any state whose truth is inconsistent with their collective observations go to zero exponentially fast.

The "SPAring robotics Technologies for Autonomous Navigation" (SPARTAN) activity of the European Space Agency (ESA) aims to develop an efficient, low-cost and accurate vision system for the future Martian exploratory rovers. The interest on vision systems for space robots has been steadily growing during the last years. The SPARTAN system considers an optimal implementation of computer vision algorithms for space rover navigation and is designated for application to a space exploratory robotic rover, such as the ExoMars. The goal of the present work is the development of an appropriate architecture for the vision system. Thus, the arrangement and characteristics of the rover's vision sensors will be defined and the required computer vision modules will be presented. The analysis will be performed taking into consideration the constraints defined by ESA about the SPARTAN system. © 2011 IEEE.
