Inquiry-based learning: Development of an introductory manufacturing processes course based on a mobile inverted pendulum robot

Abstract

This paper describes the development of an innovative introductory manufacturing processes course designed to expose students to a broad overview of fundamental concepts, methods, procedures, tools, and equipment used in the manufacturing industry. Based on an educational mobile inverted pendulum robot, students are introduced to product design and prototyping by identifying an existing problem with a component in the robot, redesigning the component using computer aided design software, and then building a prototype using additive manufacturing methods. Subsequently, a set of hypothetical design requirement changes is imposed, and various design methods and manufacturing processes that can be used to make components to satisfy these new requirements are discussed. Topics covered include integrated product design, additive manufacturing prototyping based on different technologies, plastic injection molding, sand casting, and fundamentals of both computer aided manufacturing and computer numerical control machining. Tools, fixtures, and accessories required in these processes, as well as associated challenges, are also discussed. This course adapts the inquiry-based learning active learning pedagogical approach and focuses on the development of students’ ability to conduct analytical analysis and to apply a knowledge of mathematics, science, engineering, and technology to solve practical engineering technology problems. As an introductory course designed to be offered to freshman level students, this course engages students in engineering technology related topics and stimulates their interest in manufacturing related subjects. It helps with improving the engineering student retention rate and serves as a pathway connecting students to more advanced specialized manufacturing courses such as computer numerical control machining technology. This paper presents course materials developed and student feedback as well as their evaluation of the course effectiveness based on a summative questionnaire-style survey from the first cohort of students.

Optimal fractional-order PID controller based on fractional-order actor-critic algorithm

“…The second one is to tackle the stabilizing issue of an inverted pendulum system. In fact, the inverted pendulum is a typical nonlinear, multivariable, and unstable dynamic system that is applied in many applications such as robotics [25] and general industrial processes [35]. Stabilizing issue of the inverted pendulum is used to verify that a new control method has a strong ability to address nonlinear and instability problems [62].…”

A Self-Stabilized Inverted Pendulum Made of Optically Responsive Liquid Crystal Elastomers

“…The pendulum in an inverted position is a multivariate, high-order, nonlinear, strong coupling, and natural unstable system (Nivedita and Soumitro, (2020); Gonzalez and Rossiter, (2020)). The implementation of an inverted pendulum system can effectively reflect many typical problems in control, such as nonlinear, robustness, stabilization, follow-up, and tracking problems (Junkun et al (2020); Atilla and Firat, (2020)). The stabilization of the inverted pendulum can be used to test whether a new control method has a strong ability to deal with nonlinear and unstable problems.…”

Two-loop controller design and implementations for an inverted pendulum system with optimal self-adaptive fuzzy-proportional–integral–derivative control

“…One of the systems on which control techniques are frequently tested and which forms the basis of many systems is the inverted pendulum systems (IPSs). These systems are based on many other systems in cars, aeroplanes, missiles, and human models (Anderson and Tadjbakhsh, 1989; Ma et al, 2019; Pawar and Ganguli, 2011; Shin and Kim, 2014). The fact that IPSs have unstable, fast, and non-minimum phase structures, as well as nonlinearity, made these systems important in the development of control techniques.…”
