For these reasons, undergraduate education has begun to focus on preparing engineering students to directly contribute to the design and use of such systems. However, robotics is inherently multi-disciplinary and requires knowledge of controls and automation, embedded systems, sensors, signal processing, algorithms, and artificial intelligence. This makes training the future robotics workforce a challenge. In this paper, we evaluate our experiences with project-based learning approaches to teaching robotics at the undergraduate level at Miami University. Specifically, we analyze three consecutive years of capstone design projects on increasingly complex robotics design problems for multi-robot systems. We also evaluate the laboratories taught in our course \u201cECE 314: Elements of Robotics\u201d. We have chosen these four experiences since they focus on the use of \u201ccheap\u201d first-principled robots, meaning that these robots sit on the fringe of embedded system design in that much of the student time is spent on working with a micro-controller interfacing with simple and cheap actuators and sensors. To contextualize our results, we propose the Robotic System Levels (RSL) model as a structured way to understand the levels of abstraction in robotic systems. Our main conclusion from these case studies is that, in each experience, students are exposed primarily to a subset of levels in the RSL model. Therefore, the curriculum should be designed to emphasize levels that align with educational objectives and the skills required by local industries.<\/jats:p>","DOI":"10.3390\/robotics14060070","type":"journal-article","created":{"date-parts":[[2025,5,29]],"date-time":"2025-05-29T03:30:19Z","timestamp":1748489419000},"page":"70","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["On First-Principle Robot Building in Undergraduate Robotics Education in the Robotic System Levels Model"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8286-2311","authenticated-orcid":false,"given":"Bryan","family":"Van Scoy","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, Miami University, Oxford, OH 45056, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3741-0201","authenticated-orcid":false,"given":"Peter","family":"Jamieson","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Miami University, Oxford, OH 45056, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6153-110X","authenticated-orcid":false,"given":"Veena","family":"Chidurala","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Miami University, Oxford, OH 45056, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1334","DOI":"10.1109\/PROC.1983.12775","article-title":"The OSI reference model","volume":"71","author":"Day","year":"1983","journal-title":"Proc.
