Pneumatically actuated soft robots have recently shown promise for their ability to adapt to their environment. Previously, these robots have been controlled with electromechanical components, such as valves and pumps, that are typically bulky and expensive. Here, we present an approach for controlling the gaits of soft-legged robots using simple pneumatic circuits without any electronic components. This approach produces locomotive gaits using ring oscillators composed of soft valves that generate oscillating signals analogous to biological central pattern generator neural circuits, which are acted upon by pneumatic logic components in response to sensor inputs. Our robot requires only a constant source of pressurized air to power both control and actuation systems. We demonstrate this approach by designing pneumatic control circuits to generate walking gaits for a soft-legged quadruped with three degrees of freedom per leg and to switch between gaits to control the direction of locomotion. In experiments, we controlled a basic walking gait using only three pneumatic memory elements (valves). With two oscillator circuits (seven valves), we were able to improve locomotion speed by 270%. Furthermore, with a pneumatic memory element we designed to mimic a double-pole double-throw switch, we demonstrated a control circuit that allowed the robot to select between gaits for omnidirectional locomotion and to respond to sensor input. This work represents a step toward fully autonomous, electronics-free walking robots for applications including low-cost robotics for entertainment and systems for operation in environments where electronics may not be suitable.
Interpretative phenomenological analysis (IPA) is a contemporary qualitative research method grounded in phenomenology, hermeneutics, and idiography. Philosophical principles and rigorous methodology make this approach well suited for research in counselor education and supervision. In this primer, the authors introduce counselor educators, counseling students, and counseling researchers to IPA theory and methodology and discuss considerations for implementation in counseling research.
Multiculturalism and social justice are considered major forces in the counseling profession, revolutionizing the complexity of social identity, cultural identity, and diversity. Although these major forces have influenced the profession, many challenges exist with their implementation within counselor education curriculum and pedagogy. A major challenge is the complex dynamics of privilege and oppression that both counselor educators and counseling students face. This article discusses the use of intersectionality to approach counselor education pedagogy and practice.Keywords: counselor education, intersectionality, multicultural counseling, social justice, pedagogy El multiculturalismo y la justicia social están considerados como fuerzas importantes con las que la profesión de la consejería está revolucionando la complejidad de la identidad social, la identidad cultural y la diversidad. Aunque estas fuerzas importantes han influido en la profesión, existen desafíos relacionados con su implementación en los planes curriculares y pedagogía de la educación de consejeros. Un desafío significativo es la compleja dinámica entre privilegio y opresión que enfrentan tanto los formadores de consejeros como los estudiantes de consejería. Este artículo discute el uso de la interseccionalidad para enfocar la pedagogía de la educación de consejeros y la práctica.
The emergence and global spread of COVID-19 precipitated a massive public health crisis combined with multiple incidents of racial discrimination and violence toward Asian American and Pacific Islander (AAPI) communities. Although East Asian communities are more frequently targeted for instances of pandemic-related racial discrimination, multiple disparities converge upon Filipino communities that affect their access to mental health care in light of COVID-19. This article empowers professional counselors to support the Filipino community by addressing three main areas: (a) describing how COVID-19 contributes to racial microaggressions and institutional racism toward Filipino communities; (b) underscoring how COVID-19 exacerbates exposure to stressors and disparities that influence help-seeking behaviors and utilization of counseling among Filipinos; and (c) outlining how professional counselors can promote racial socialization, outreach, and mental health equity with Filipino communities to mitigate the effects of COVID-19.
Because of demographic changes and the prioritization of Medicare reimbursement, there is greater attention to the mental health needs of older adults. To better understand the current state of gerontological counseling research, the authors completed a content analysis of counseling scholarship spanning 26 years. Only 1.68% of the articles reviewed focused on topics related to gerontological counseling. The authors analyzed publishing patterns, topics explored, and the roles of theory and empirical research in gerontological counseling research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
