TL;DR: The proposed robot, namely, quadrupedal human-assistive robotic platform (Q-HARP), utilizes legged locomotion to provide an unprecedented potential to adapt to a wide variety of challenging terrains, many of which are common in people’s daily life.
Abstract:
With the rapid expansion of older adult populations around the world, mobility impairment is becoming an increasingly challenging issue. For the assistance of individuals with mobility impairments, there are two major types of tools in the current practice, including the passive (unpowered) walking aids (canes, walkers, rollators, etc.) and wheelchairs (powered and unpowered). Despite their extensive use, there are significant weaknesses that affect their effectiveness in daily use, especially when challenging uneven terrains are encountered. To address these issues, the authors developed a novel robotic platform intended for the assistance of mobility-challenged individuals. Unlike the existing assistive robots serving similar purposes, the proposed robot, namely, quadrupedal human-assistive robotic platform (Q-HARP), utilizes legged locomotion to provide an unprecedented potential to adapt to a wide variety of challenging terrains, many of which are common in people’s daily life (e.g., roadside curbs and the few steps leading to a front door). In this paper, the design of the robot is presented, including the overall structure of the robot and the design details of the actuated robotic leg joints. For the motion control of the robot, a joint trajectory generator is formulated, with the purpose of generating a stable walking gait to provide reliable support to its human user in the robot’s future application. The Q-HARP robot and its control system were experimentally tested, and the results demonstrated that the robot was able to provide a smooth gait during walking.

TL;DR: The Innovate Practice Work In Progress as discussed by the authors course is an integrated approach into a course-based STEM undergraduate research experience that provides students with proven hands-on experience that teaches integration of discipline-specific knowledge with engineering practice on challenging multidisciplinary projects.
Abstract: This Innovate Practice Work In Progress paper presents an integrated approach into a course-based STEM undergraduate research experience. The objective of the course is to provide students with proven hands-on experience that teaches integration of discipline-specific knowledge with engineering practice on challenging multidisciplinary projects. The course design, instruction delivery, project preparation, team formation, system, and sub-system construction, as well as student and course assessment will be discussed and faced challenges emphasized. Initial feedback from students and faculty shows that the benefits include increasing interaction with the faculty and increasing intellectual maturity, knowledge, and confidence for the students. As for the faculty, this includes furthering of research projects and achieving some of program objectives as required by accreditation boards.
