On Sensorless Collision Detection And Measurement Of External Forces In Presence Of Modeling Inaccuracies, Vahid Sotoudehnejad
On Sensorless Collision Detection And Measurement Of External Forces In Presence Of Modeling Inaccuracies, Vahid Sotoudehnejad
Electronic Thesis and Dissertation Repository
The field of human-robot interaction has garnered significant interest in the last decade. Every form of human-robot coexistence must guarantee the safety of the user. Safety in human-robot interaction is being vigorously studied, in areas such as collision avoidance, soft actuators, light-weight robots, computer vision techniques, soft tissue modeling, collision detection, etc. Despite the safety provisions, unwanted collisions can occur in case of system faults. In such cases, before post-collision strategies are triggered, it is imperative to effectively detect the collisions. Implementation of tactile sensors, vision systems, sonar and Lidar sensors, etc., allows for detection of collisions. However, due to …

Scheduling For A Small Satellite For Remote Sensed Data Collection, Donovan Torgerson, Christoffer Korvalnd, Jeremy Straub, Ronald Marsh
Jeremy Straub
Small satellites, such as CubeSats, serve as excellent platforms for the collection of data that can be supplied to a geographic information system. To serve this need, they require a robust and lightweight task scheduler due to their limited onboard power production capabilities as well as internal space restrictions. Because of these constraints, schedules must be optimized; however, the scheduling optimization process must be performed using limited processing (CPU) power.
Several considerations must be taken into account in order to make a scheduler for these systems. This poster highlights requirements such as inter-dependency of onboard systems, and limited windows of …

Computer-Based Stereoscopic Parts Recognition For Robotic Applications, Ahmad A. Fayed
Computer-Based Stereoscopic Parts Recognition For Robotic Applications, Ahmad A. Fayed
UNLV Theses, Dissertations, Professional Papers, and Capstones
Most of robotic handling and assembly operations are based on sensors such as range and touch sensors. In certain circumstances, such as in the presence of ionizing radiation where most customary sensors will degrade over time due to radiation exposure, these sensors won't function properly. Utilizing two or more cameras (stereo vision) located outside the target zone and analyzing their images to identify location and dimensions of parts within the robot workspace is an alternative for using sensors. Object Recognition is affected by the light condition which oftentimes causes the gray-scale or red, green, and blue values to have a …
A Hybrid Visual Control Scheme To Assist The Visually Impaired With Guided Reaching Tasks, Duane Jacques
A Hybrid Visual Control Scheme To Assist The Visually Impaired With Guided Reaching Tasks, Duane Jacques
Electronic Thesis and Dissertation Repository
In recent years, numerous researchers have been working towards adapting technology developed for robotic control to use in the creation of high-technology assistive devices for the visually impaired. These types of devices have been proven to help visually impaired people live with a greater degree of confidence and independence. However, most prior work has focused primarily on a single problem from mobile robotics, namely navigation in an unknown environment. In this work we address the issue of the design and performance of an assistive device application to aid the visually-impaired with a guided reaching task. The device follows an eye-in-hand, …

Techniques And Directions For Building Very Large Agent Teams, Paul Scerri, Joseph A. Giampapa, Katia Sycara
Joseph Andrew Giampapa
We have developed probabilistic algorithms that leverage the associates network for distributed plan instantiation, role allocation, information sharing and adjustable autonomy with a team. By developing such new algorithms, we have been able to build teams of hundreds of cooperating agents, and test specific behaviors among tens of thousands of agents. In this paper, we describe the algorithms that we have developed, the tests that we subjected them to, and sketch some of the key challenges that remain to be addressed.

Certain robot missions need to perform predictably in a physical environment that may only be poorly characterized in advance. We have previously developed an approach to establishing performance guarantees for behaviorbased controllers in a process-algebra framework. We extend that work here to include random variables, and we show how our prior results can be used to generate a Dynamic Bayesian Network for the coupled system of program and environment model. Verification is reduced to a filtering problem for this network. Finally, we present validation results that demonstrate the effectiveness of the verification of a multiple waypoint robot mission using this …

Characterization Of Extended And Simplified Intelligent Water Drop (Siwd) Approaches And Their Comparison To The Intelligent Water Drop (Iwd) Approach, Jeremy Straub, Eunjin Kim
Characterization Of Extended And Simplified Intelligent Water Drop (Siwd) Approaches And Their Comparison To The Intelligent Water Drop (Iwd) Approach, Jeremy Straub, Eunjin Kim
Jeremy Straub
This paper presents a simplified approach to performing the Intelligent Water Drops (IWD) process. This approach is designed to be comparatively lightweight while approximating the results of the full IWD process. The Simplified Intelligent Water Drops (SIWD) approach is specifically designed for applications where IWD must be run in a computationally limited environment (such as on a robot, UAV or small spacecraft) or where performance speed must be maximized for time sensitive applications. The SWID approach is described and compared and contracted to the base IWD approach.

Dexterous Hexrotor Uav Platform, Guangying Jiang
Electronic Theses and Dissertations
Mobile manipulation is a hot area of study in robotics as it unites the two classes of robots: locomotors and manipulators. An emerging niche in the field of mobile manipulation is aerial mobile manipulation. Although there has been a fair amount of study of free-flying satellites with graspers, the more recent trend has been to outfit UAVs with graspers to assist various manipulation tasks. While this recent work has yielded impressive results, it is hampered by a lack of appropriate testbeds for aerial mobile manipulation, similar to the state of ground-based mobile manipulation a decade ago. Typical helicopters or quadrotors …

Development Of Pneumatic Robot For Outreach, Eshamogbo E. Ojuba, John Lumkes
The Summer Undergraduate Research Fellowship (SURF) Symposium
To encourage the current generation of high school and middle school students to pursue careers in engineering, it is important to have challenging hands-on engineering activities for them. Such activities should be interesting, compelling, and, most importantly, educative. A mini-excavator was built for fluid power outreach, but this tool only demonstrates fluid power, without showing other important aspects of engineering. The tool being developed is able to demonstrate fluid power, as well as other important aspects of engineering, such as controls, electronics, and programming. This tool is an electronically-controlled device that allows the user control a pneumatic circuit, coupled with …

Performance Guarantees For C-Wmd Robot Missions, Shu Jiang, Ronald C. Arkin, Damian M. Lyons, Tsung-Ming Liu, Dagon Harrington
Faculty Publications
Robotics has been considered as one of the five key technology areas for defense against attacks with weapons of mass destruction (WMD). However, due to the mass impact nature of WMD, failures of counter-WMD (C-WMD) missions can have catastrophic consequences.To ensure robot's success in carrying out C-WMD missions, we have developed a novel verification framework in providing performance guarantees for behavior-based and probabilistic robot algorithms in complex real-world environments. This paper describes the system architecture and discusses how the verification framework can be used to provide pre-mission performance guarantees for robots in executing C-WMD missions.
Reasoning Across Language And Vision In Machines And Humans, Andrei Barbu
Reasoning Across Language And Vision In Machines And Humans, Andrei Barbu
Open Access Dissertations
Humans not only outperform AI and computer-vision systems, but use an unknown computational mechanism to perform tasks for which no suitable approaches exist. I present work investigating both novel tasks and how humans approach them in the context of computer vision and linguistics. I demonstrate a system which, like children, acquires high-level linguistic knowledge about the world. Robots learn to play physically-instantiated board games and use that knowledge to engage in physical play. To further integrate language and vision I develop an approach which produces rich sentential descriptions of events depicted in videos. I then show how to simultaneously detect …

Hypothesize-And-Verify Based Solutions For Place Recognition And Mobile Robot Self-Localization In Interior Hallways, Khalil Mustafa Ahmad Yousef
Open Access Dissertations
There is much research interest currently in having mobile robots build accurate and visually dense models ofinterior space as they traverse through such spaces. One of the interesting problems that has came out of this research is that of visual place recognition and self-localization. This is the problem that forms the focus of the present dissertation. We show how dense and accurate 3D models of the interior space can be constructed using a hierarchical sensor-fusion architecture. Our system fuses images from a single photometric camera with range data from a laser scanning sensor. The range data used is rudimentary--the range …

We study the detailed locomotor mechanics of a small, lightweight robot (DynaRoACH, 10 cm, 25 g) which can move on a granular substrate of closely packed 3 mm diameter glass particles at speeds up to 50 cm/s (5 body length/s), approaching the performance of small, highperforming, desert-dwelling lizards. To reveal how the robot achieves this high performance, we used high speed imaging to capture kinematics, and developed a numerical multi-body simulation of the robot coupled to an experimentally validated discrete element method (DEM) simulation of the granular media. Average forward speeds measured in both experiment and simulation agreed well, and …
Semantically Grounded Learning From Unstructured Demonstrations, Scott D. Niekum
Semantically Grounded Learning From Unstructured Demonstrations, Scott D. Niekum
Open Access Dissertations
Robots exhibit flexible behavior largely in proportion to their degree of semantic knowledge about the world. Such knowledge is often meticulously hand-coded for a narrow class of tasks, limiting the scope of possible robot competencies. Thus, the primary limiting factor of robot capabilities is often not the physical attributes of the robot, but the limited time and skill of expert programmers. One way to deal with the vast number of situations and environments that robots face outside the laboratory is to provide users with simple methods for programming robots that do not require the skill of an expert.
For this …
Mobile Robot Navigation For Person Following In Indoor Environments, Ninad Pradhan
Mobile Robot Navigation For Person Following In Indoor Environments, Ninad Pradhan
All Dissertations
Service robotics is a rapidly growing area of interest in robotics research. Service robots inhabit human-populated environments and carry out specific tasks. The goal of this dissertation is to develop a service robot capable of following a human leader around populated indoor environments. A classification system for person followers is proposed such that it clearly defines the expected interaction between the leader and the robotic follower. In populated environments, the robot needs to be able to detect and identify its leader and track the leader through occlusions, a common characteristic of populated spaces. An appearance-based person descriptor, which augments the …
Continuum Robotic Surface: Forward Kinematic Analysis And Implementation, Jessica Merino
Continuum Robotic Surface: Forward Kinematic Analysis And Implementation, Jessica Merino
All Theses
This thesis presents a new class of biologically inspired robots: continuum robotic surfaces. This work is fueled by the question: can the interaction between robot and environment be advanced with “programmable surfaces in space?” The novelty of continuum robotic surfaces lies in their ability to be actively controlled and reconfigured in what we believe is the current “missing dimension” in robot movements — two–dimensional space. We believe that such surfaces will lend themselves to more complex applications. However, to effectively deploy such surfaces for these complex applications, kinematic models will be necessary to plan and control desired configurations. The forward …

Modeling, Control, And Motion Analysis Of A Class Of Extensible Continuum Manipulators, Apoorva Kapadia
All Dissertations
In this dissertation, the development of a kinematic model, a configuration-space controller, a master-slave teleoperation controller, along with the analysis of the self-motion properties for redundant, extensible, continuous backbone (continuum) ``trunk and tentacle' manipulators are detailed. Unlike conventional rigid-link robots, continuum manipulators are robots that can bend at any point along their backbone, resulting in new and unique modeling and control issues. Taken together, these chapters represent one of the first efforts towards devising model-based controllers of such robots, as well as characterizing their self-motion in its simplest form.
Chapter 2 describes the development of a convenient set of generalized, …

Decentralized Collision Avoidance, Jayasri K. Janardanan
Department of Computer Science and Engineering: Dissertations, Theses, and Student Research
Autonomous Robots must carry out their tasks as independently as possible and each robot may be assigned different tasks at different locations. As these tasks are being performed, the robots have to navigate correctly such that the assigned tasks are completed efficiently, while also avoiding each other and other obstacles. To accomplish effective navigation, we must ensure that the robots are calibrated to avoid colliding with any kind of object on its path. Each robot has to sense the obstacles on its path and take necessary corrective measure to avoid those obstacles. In a situation with multiple robots, robots may …
Development Of A Novel Handheld Device For Active Compensation Of Physiological Tremor, Abhijit Saxena
Development Of A Novel Handheld Device For Active Compensation Of Physiological Tremor, Abhijit Saxena
Abhijit Saxena
In microsurgery, the human hand imposes certain limitations in accurately positioning the tip of a device such as scalpel. Any errors in the motion of the hand make microsurgical procedures difficult and involuntary motions such as hand tremors can make some procedures significantly difficult to perform. This is particularly true in the case of vitreoretinal microsurgery. The most familiar source of involuntary motion is physiological tremor. Real-time compensation of tremor is, therefore, necessary to assist surgeons to precisely position and manipulate the tool-tip to accurately perform a microsurgery. In this thesis, a novel handheld device (AID) is described for compensation …

Verifying Performance For Autonomous Robot Missions With Uncertainty, Damian M. Lyons, Ronald Arkin, Tsung-Ming Liu, Shu Jiang, Paramesh Nirmal
Faculty Publications
Establishing performance guarantees for robot missions is especially important for C-WMD applications. Software verification techniques, such as model checking (Clark 1999, Jhala & Majumdar 2009), can be applied to robotic applications but characteristics of this application area, including addition of a robot environment model and handling continuous spatial location well, exacerbate state explosion, a key weakness of these methods. We have proposed an approach to verifying robot missions that shifts the focus from state-based analysis onto the solution of a set of flow equations (Lyons et al. 2012). The key novelty introduced in this paper is a probabilistic spatial representation …

Leading research in robotics, especially in the areas of computer vision, planning, and probabilistic learning, require a mobile robot platform to program. The design and construction of such a platform is a laborious task, calling upon knowledge from many branches of engineering. Additionally, hot research topics in robotics such as vision-based Simultaneous Localization and Mapping (SLAM), advanced trajectory planning algorithms, and adaptive control for collision avoidance contain algorithms that build upon a localization and mapping architecture which is time-consuming to program in itself. To bring future senior project teams from Cal Poly's computer engineering and computer science departments closer to …

Flarebot - Analysis Of An Autonomous Robot, Sanat S. Sahasrabudhe
Computer Engineering
Autonomous robots are increasing in popularity for educational, research, and household purposes. This report analyzes the design and functionality of one such example, called FlareBot, which is designed to self-navigate and stack cans. Specifically, the robot is designed to follow a fixed path for navigation, and stack any cans it comes across. Once a maximum number of cans is stacked, the robot releases them and restarts the process. The design is achieved using three DC motors, two servo motors, one line sensor, and one infrared sensor. Designing autonomous robots is a strong test of the engineering design process, which includes …

Creating homemade robots are becoming a popular hobby among engineers. With the dramatic reduction in costs over the past few decades, it is finally possible to build a personal automated mailbox. Microcontrollers needed to function as the brains of the robot are also becoming powerful enough that relatively complicated instructions could be programmed into the robot to handle a plethora of sensors and peripherals. In order to demonstrate how the Computer Engineering department models the synthesis of computer science and electrical engineering, the topic chosen was robotics, specifically, a stuffed bear robot.
The microcontroller chosen was the Arduino Mega 2560 …
