    A multipurpose robotic glove designed to teach sign language through guided manual motions
    (Industry, Engineering & Conference Management Systems Conference, 2021-03) Joshi, Soham; Malik, Raaghav
    Projections show the numbers of deaf and deafblind individuals are quickly increasing, as both the number of deaf and blind individuals are expected to double within the next 50 years. Additionally, there is limited support for deafblind individuals, as they have little sensory access to the world. Most existing solutions are inadequate because they are either not portable, readily accessible or are very expensive. The goal of our project is to create a low cost, accessible solution for those with these disabilities: a portable device that utilizes the sense of touch to teach sign language, instead of conventional sign language learning methods that rely on sight. By doing this, a more immersive and personalized experience is created. The implementation of this solution is two-pronged: first, the physical portion of the solution is equipped with servo motors that control the pulling and release of a cord threaded through rings on the fingers that moves the user's hands into various sign language positions, which is closely modeled after human hand anatomy. Secondly, feasibility is determined for an AI algorithm to take in data from an external camera to efficiently add new signs to the glove, and also to track the user's sign language patterns and rate the user's accuracy with various signs. Through these mechanisms the user is engaged in learning new signs and expanding their sign language vocabulary, all without their sense of sight. We were successful in creating a working prototype analyzed through hand-tracking mechanisms, and achieving a 91-92% accuracy for the American Sign Language alphabet.

    A brain computer interface system for the improvement of cognitive and communication abilities for patients with neuromuscular disorders
    (Industry, Engineering & Conference Management Systems Conference, 2021-03) Ramakrishnan, Navya
    More than 16 million people in the United States are living with cognitive impairment. Reports suggest that 12,000-15,000 people have amyotrophic lateral sclerosis and approximately 17 million people have cerebral palsy, globally. The engineering goals are (i) to design an experimental study to analyze and improve cognitive performance and (ii) to develop a communication aid to support people with neuromuscular disorders using non-invasive brain-computer interface. A low-cost EEG device, Emotiv EPOC+ is used to record EEG data and a Python interface is used to stream the data for analysis. The features extracted are used to train the classifier, Linear Discriminant Analysis. The participants' cognitive performances were measured initially and after giving 20 days of feedback sessions with alpha-numeric speller. The performances were in the range of 76%- 81% initially and accuracy improved for all the participants and are in the range of 84%-89.3% after feedback sessions. The proposed feedback training design is an excellent way to improve cognitive abilities and can be used for healthy individuals as well as people with attention deficiency to improve their attention. A software application is developed to use the system as a communication aid for neuromuscular disorder patients who are unable to communicate. The accuracy in identifying the words of participants' choice are measured only using their brain activity. The communication aid was able to predict more than 91% of the words correctly. The system is low-cost and easy-to-use with a short setup time regardless of users' expertise.

    Comparing the regional and international accreditation programs of NCAAA and ABET for undergraduate engineering education evaluations
    (Industry, Engineering & Conference Management Systems Conference, 2021-03) Alarifi, Ibrahim M.; Rahman, Muhammad M.; Asmatulu, Ramazan
    This research study was focused on the accreditation of a local university and its programs during the 2017-2018 and 2018-2019 periods. Accreditation requires that the university be under the consideration by an autonomous agency for the quality assurance. Accreditation can be done for the entire institution or for individual programs within an institution. Accreditation is a voluntary process that many institutions go through with multiple steps. Usually, universities request accreditation agencies to assess their programs, faculty, and students' achievements to establish if they meet the quality requirements every six years. When requirements are met, the organization is regularly reassessed and accredited to make sure that the whole body persists in meeting the standards. Majmaah University (MU) of Saudi Arabia has been recently prepared for both regional (National Commission for Academic Accreditation and Assessment - NCAAA) and international (Accreditation Board for Engineering and Technology - ABET) accreditation programs. Most of the undergraduate engineering teaching programs were certified by both NCAAA and ABET. These accreditation programs have mainly similar outcomes although there were some small variations. This study provides the details on the similarity, differences, strengths, and weaknesses of the two accreditation systems and the required documentations to meet the accreditation criteria and demands.

    A virtual STEM outreach program for elementary and middle school students during COVID-19
    (Industry, Engineering & Conference Management Systems Conference, 2021-03) Shen, Anthony
    Gender inequality has been a persistent problem in higher education and industry in the STEM fields in the United States. While progress has been made in the last decade, there is a potential for increasing inequality in the time of COVID-19 with the inability to engage students in a face-to-face forum. In order to introduce elementary and middle school students to robotics and STEM, a monthly, virtual online outreach curriculum, mostly led by female students has been developed to stimulate student excitement and encourage girls to get involved in the fields of science and technology. Robotics is used as a conduit to teach and stimulate interest in STEM. A fun, hands on, and interactive curriculum for a series of educational online workshops has been developed, covering the engineering design process, competitive robotics, 3D CAD tutorial, programming, and robot mechanics. Our findings suggest that in elementary school, girls and boys are approximately equally interested in STEM. The outreach workshop appears to be a useful way to encourage and engage boys and girls in STEM virtually during COVID 19.

    Real-time kinematics directed swarm robotics for construction 3D printing
    (Industry, Engineering & Conference Management Systems Conference, 2021-03) Wang, Darren; Zhu, Robert
    Architectural advancements in housing are limited by traditional construction techniques. Construction 3D printing introduces freedom in design that can lead to improvements in building design, resource efficiency, and cost. Designs for current construction 3D printers have limited build volume and, at the scale needed for printing houses, transportation and setup could become issues. This work is an exploration of and proposal for a swarm robotics-based construction 3D printing system that could bypass these issues. In this system, a central computer will coordinate the movement and actions of a swarm of robots which are each capable of extruding concrete in a programmable path and navigating on both the ground and the structure. The central computer will create paths for each robot to follow by processing the G-code obtained from slicing a CAD model of the intended structure. The robots will use readings from real-time kinematics (RTK) modules to keep themselves on their designated paths. The current progress in hardware and software is available on GitHub for collaborative development of this proposed approach towards construction.
