Ground Robotic Hand Applications for the Space Program study (GRASP)

This document reports on a NASA-STDP effort to address research interests of the NASA Kennedy Space Center (KSC) through a study entitled, Ground Robotic-Hand Applications for the Space Program (GRASP). The primary objective of the GRASP study was to identify beneficial applications of specialized end-effectors and robotic hand devices for automating any ground operations which are performed at the Kennedy Space Center. Thus, operations for expendable vehicles, the Space Shuttle and its components, and all payloads were included in the study. Typical benefits of automating operations, or augmenting human operators performing physical tasks, include: reduced costs; enhanced safety and reliability; and reduced processing turnaround time

Design and evaluation of a soft and wearable robotic glove for hand rehabilitation

In the modern world, due to an increased aging population, hand disability is becoming increasingly common. The prevalence of conditions such as stroke is placing an ever-growing burden on the limited fiscal resources of health care providers and the capacity of their physical therapy staff. As a solution, this paper presents a novel design for a wearable and adaptive glove for patients so that they can practice rehabilitative activities at home, reducing the workload for therapists and increasing the patient’s independence. As an initial evaluation of the design’s feasibility the prototype was subjected to motion analysis to compare its performance with the hand in an assessment of grasping patterns of a selection of blocks and spheres. The outcomes of this paper suggest that the theory of design has validity and may lead to a system that could be successful in the treatment of stroke patients to guide them through finger flexion and extension, which could enable them to gain more control and confidence in interacting with the world around them

Design and Testing of Torveastro: An Outer Space Service Robot

Space robots are one of the most promising solutions for on-orbit servicing (OOS) duties like docking, berthing, refueling, re-pairing, upgrading, transporting, rescuing, and orbital trash disposal. Numerous enabling techniques and technological demonstration missions have been developed and completed over the past two decades. There have been several successful manned on-orbit service missions, but unmanned service missions have not yet been conducted. Robotic maintenance continues to be an important area of investigation with numerous technical challenges. This report outlines the design and initial testing of Torveastro, an astronaut service robot. The specifications are provided concurrently with the design and simulation. In comparison with the simulation results, preliminary tests demonstrated promising behavior for future development

Development and Design of ROV Manipulator

The thesis is carried out in collaboration with the student organization UiS Subsea. The primary objective of this thesis is to design and develop a manipulator for the ROV, named YME, using the product development process (PDP). The end goal is to showcase the final product at the MATE ROV Competition 2023. The importance of sustainability has been highlighted in recent years, and this year, MATE ROV Competition focuses on the United Nations Decade of Ocean Science for Sustainable development (2021-2030), and challenge students to contribute to UNs Sustainability goals by seeking sustainable solutions for their projects. The product development process consisted of four phases: planning, concept development, concept generation, and product concept selection. The planning process focused on resource allocation, declaring a mission statement, and establishing a good foundation for the process ahead. Gathering benchmarking information and establishing target specifications was a crucial part of the concept development phase, prior to the concept generation process, as the information and specifications served as a guidance and outline for the concepts to be generated. By a circular economy approach, the reuse of old components within UiS Subsea was evaluated, and potential components were located. The circular economy approach influenced design decisions, and resulted in cost and timeefficiency, and contribution towards sustainability in engineering practices. Concepts were generated for both the manipulator arm and end-effector, and the most promising ones were selected for further development. Eventually one concept for the arm, and one for the end-effector, was selected and further developed through detailed design. Through detailed design, a complete CAD model of the manipulator was made, also material was selected and necessary calculations were performed. The outcome was a three degree of freedom manipulator arm with a rotating end-effector, pitch function, xv and a telescope function. Through prototyping and extensive testing, the design was evaluated and deemed sufficient according to customer needs and target specifications. The outcome of the project was a fully functional ROV Manipulator able to perform all the required MATE tasks, and contributed greatly towards the successful qualification to the 2023 MATE ROV Competition. However, there was room for further improvement and optimization of both the manipulator and the process, and hopefully the manipulator can serve as a foundation for future UiS Subsea manipulator projects.The thesis is carried out in collaboration with the student organization UiS Subsea.
