Teaching Robotics by Building Autonomous Mobile Robots Using the Arduino

Abstract

In recent years I have been teaching a project-based Robotics course within our quarterbased Mechanical Engineering program using the Stamp microcontroller. Students work in teams to complete a number of weekly lab exercises designed to sufficiently build their robotics expertise to the level that they can complete a project to design, build, and test an autonomous mobile robot to successfully complete an assigned task of their choosing. The course was structured in such a way that course materials laid out everything explicitly for the students since time was short on a ten-week quarter schedule. They simply followed the directions given. This fall, we changed to a semester schedule, changed our microcontroller from the Stamp to the popular Arduino, and restructured the entire course. Since extensive information is available on-line and in the literature for the Arduino, the course philosophy and structure has changed. Instead of providing students with all the information they need, students are now presented with a task, and they are told to go discover how to do it. As a result, the course is more challenging and interesting for them. This is aided by the additional time available in the semester schedule and by the wealth of information available for the Arduino. The paper discusses the current structure of the course, how independent team effort is evaluated, and the problems encountered in switching from a Stamp-based ten week quarter course to an Arduino-based "self-discovery" semester course.

Using Arduino Kits and Discord to Implement A Fully Remote Laboratory Course During the COVID-19 Pandemic

“…The Arduino platform has become very popular in college-level education in the past decade, and most of the literature reports on its use by first-year or second-year engineering students (e.g., [2], [3], [4], [10]). Our course is senior-level; as such the students are expected to have advanced knowledge about programming and control theory.…”

“…Low-cost microcontrollers such as Arduino and Raspberry Pi have been used in engineering courses for more than one decade [2], [3], [4], [5]. Compared with the prior research about using Arudino platforms in the classroom, we used the Arduino in a senior-level laboratory course with more in-depth C/C++ programming.…”

Introducing Automation Concepts in a "Mechanisms and Robotics" Course

“…Arduinos also appear in various other contexts. They are used for teaching basic concepts in introductory Robotics courses [5] [6]. Project specific examples of Arduino systems include: use in a CNC plotter [7]; combined with a joystick for robot control [8]; to create a Spirograph style drawing machine [9]; and combined with LabView and SolidWorks to create virtual simulations of mechanisms and robots [10].…”
