In recent time, manufacturing environment are bracing higher end technologies to achieve high productivity, efficiency and effectiveness. Due to the adoption of the sophisticated technologies, the system is becoming very complex and stochastic. Moreover, the manufacturing system is interconnected among its different subsystems and components, which cannot be described only through the theoretical explanation. Here, computer simulation can be integrated to design and visualize the stochastic and complex system. This paper uses the advantage of simulation to describe a series classroom activity using SIMIO software, which are deployed in industrial systems simulation course in the University of Texas at El …
A Biomimetic Approach To Controlling Restorative Robotics, Matthew T. Boots
A Biomimetic Approach To Controlling Restorative Robotics, Matthew T. Boots
Graduate Theses, Dissertations, and Problem Reports
Movement is the only way a person can interact with the world around them. When trauma to the neuromuscular systems disrupts the control of movement, quality of life suffers. To restore limb functionality, active robotic interventions and/or rehabilitation are required. Unfortunately, the primary obstacle in a person’s recovery is the limited robustness of the human-machine interfaces. Current systems rely on control approaches that rely on the person to learn how the system works instead of the system being more intuitive and working with the person naturally. My research goal is to design intuitive control mechanisms based on biological processes termed …
Ambiqual – A Full Reference Objective Quality Metric For Ambisonic Spatial Audio, Miroslaw Narbutt, Andrew Allen, Jan Skoglund, Michael Chinen, Andrew Hines
Ambiqual – A Full Reference Objective Quality Metric For Ambisonic Spatial Audio, Miroslaw Narbutt, Andrew Allen, Jan Skoglund, Michael Chinen, Andrew Hines
Conference papers
Streaming spatial audio over networks requires efficient encoding techniques that compress the raw audio content without compromising quality of experience. Streaming service providers such as YouTube need a perceptually relevant objective audio quality metric to monitor users’ perceived quality and spatial localization accuracy. In this paper we introduce a full reference objective spatial audio quality metric, AMBIQUAL, which assesses both Listening Quality and Localization Accuracy. In our solution both metrics are derived directly from the B-format Ambisonic audio. The metric extends and adapts the algorithm used in ViSQOLAudio, a full reference objective metric designed for assessing speech and audio quality. …
Skin Deformation Feedback For Force Sensory Substitution In Teleoperation And Virtual Reality Training, Samuel Schorr
Skin Deformation Feedback For Force Sensory Substitution In Teleoperation And Virtual Reality Training, Samuel Schorr
Link Foundation Modeling, Simulation and Training Fellowship Reports
For this work, we developed a wearable skin deformation device that is worn on the tip of the finger. The devices have two separate components, the first of which is a finger grounding interface that straps to the medial phalanx. The interface holds a magnetic tracking sensor from an Ascension 3D Guidance trakSTAR system, which provides tracking information about the position and orientation of the fingers in free space at 200 Hz.
A Virtual Reality Based Powered Wheelchair Simulator, Yuliia Sergeeva
A Virtual Reality Based Powered Wheelchair Simulator, Yuliia Sergeeva
Masters Theses
Power wheelchairs provide great assistance for people with locomotion disabilities. However, for those who have tremor, operation of the wheelchair can be challenging and result in a chance to get into an accident. The focus of this research project is to create a semi-virtual reality power wheelchair driving simulator that can be used for testing a notch filter for tremors in a safe laboratory environment and obtain data on human operator movements for future mathematical modeling. The simulator incorporates a realistic and immersive virtual environment and power wheelchair movement into it. For the experiment, a physical PWC joystick was connected …
Vrshape: A Virtual Reality Tool For Shaping Movement Compensation, Matthew Hale Foreman
Vrshape: A Virtual Reality Tool For Shaping Movement Compensation, Matthew Hale Foreman
Arts & Sciences Electronic Theses and Dissertations
The majority of persons living with chronic stroke experience some form of upper extremity motor impairment that affects their functional movement, performance of meaningful activities, and participation in the flow of daily life. Stroke survivors often compensate for these impairments by adapting their movement patterns to incorporate additional degrees of freedom at new joints and body segments. One of the most common compensatory movements is the recruitment of excessive trunk flexion when reaching with the affected upper extremity. Long-term use of these compensations may lead to suboptimal motor recovery and chronic pain or injury due to overuse. Rehabilitation focuses on …
Optimizing The Robot Arm Movement Time Using Virtual Reality Robotic Teaching System
Optimizing The Robot Arm Movement Time Using Virtual Reality Robotic Teaching System
Faculty of Engineering University of Malaya
Robots play an important role in performing operations such as welding, drilling and screwing parts in manufacturing. Optimizing the robot arm movement time between different points is an important task which will minimize the make-span and maximize the production rate. But robot programming is a complex task whereby the user needs to teach and control the robot in order to perform a desired action. In order to address the above problem, an integrated 3-dimensional (3D) simulation software and virtual reality (VR) system is developed to simplify and speed up tasks and therefore enhance the quality of manufacturing processes. This system …
Augmented Reality Navigation Interfaces Improve Human Performance In End-Effector Controlled Telerobotics, Keshav Chintamani
Augmented Reality Navigation Interfaces Improve Human Performance In End-Effector Controlled Telerobotics, Keshav Chintamani
Wayne State University Dissertations
On the International Space Station (ISS) and space shuttles, the National Aeronautics and Space Administration (NASA) has used robotic manipulators extensively to perform payload handling and maintenance tasks. Teleoperating robots require expert skills and optimal performance is crucial to mission completion and crew safety. Degradation in performance is observed when manual control is mediated through remote camera views, resulting in poor end-effector navigation quality and extended task completion times. This thesis explores the application of three-dimensional augmented reality (AR) interfaces specifically designed to improve human performance during end-effector controlled teleoperations. A modular telerobotic test bed was developed for this purpose …
