: Robotics Technology in the department of Computer Engineering Technology atCUNY-New York City College of Technology is offered as a technical elective to its senior students. Inaddition to introducing fundamental subjects in both Autonomous Mobile Robot [1] and RoboticManipulator [2], another goal is to prepare students with necessary knowledge and skills for roboticprogramming and design. The course is structured to have a 2.5-hour lecture session and a 2.5-hour labsession each week. When teaching onsite the school (i.e., in-person), students were given physical robotsfor implementation of the algorithms discussed during lectures. When access to laboratory facilities wasimpossible under e-learning (for example, during the COVID-19 pandemic

This is accomplished on thehardware through the employment of a wireless embedded Satellite control board programmedwith Simulink and a LabVIEW-based Base Station.

, assembly of the associated electronics during the lab period isoften included. Presently, labs are often either: 1) a series of disconnected/disjointed labs onlyfocused on a single-sensor-application or 2) pre-fabricated equipment setups purchased fromeducation companies, which are often costly and have a small scope with very limited possibilityfor future modifications. Both also suffer from “cookie-cutter” type approaches, which stiflestudents from experiencing true engineering design methodologies. Both existing solutions oftenhave no flexibility to be switched between in-person and online teaching; if it is even possible tobe implemented online.In this BYOE presentation, we present the design, fabrication, and implementation of a hybridSensors

Options for Analog and Digital Circuits Suitable for In-Class or At-Home ExperimentsAbstractDuring a pandemic such as COVID-19, many institutions need to increase the portion of onlineinstruction and enforce social distancing in the classroom. It is challenging to maintain the samelevel of hands-on lab experience, and yet lab experience is essential for many courses andperhaps the most effective pedagogy to help students learn. There are three alternatives totraditional labs: (1) purely virtual simulations, via an app or software, an online platform, or avirtual environment; (2) remote labs to run experiments on actual hardware hosted off-site viainternet and parallel access; and (3) individual lab kits so that each student can

The faculty members who developed the course identified the need to ensure that everystudent enrolled in the course has a 3D printer in their possession for the duration of the course tomaximize the hands-on applications of the course. Students are given two options forcompleting the laboratory course depending on their discretionary funds. Option 1 is to purchasea commercially available inexpensive kit, which they build and use for the course and then keepafter the completion of the course. Option 2 is to borrow a printer from the department, whichthey will need to repair or upgrade, use for the duration of the course, and then return to

However, recent data[1] from three institutions and nearly 3000 students showthere was no statistically measurable lab benefit in boosting content mastery of physics.Students perform similarly on questions whose target content was reinforced by a lab activity ason questions whose target content lacked an associated lab activity. This result, althoughsurprising, makes a strong case for reexamining the purpose of labs and how they are taught. Another cause of the

Thisleaves them at a disadvantage both in terms of success in mastering the curriculum and level ofcompetitiveness for internships [1, 2]. As these students move through a typical engineeringcurriculum, a focus on abstract theory and mathematical concepts over physical applications andmeasurable observations will fail to give them the necessary hands-on experience, reducing thechances that the information will be retained over the long term [3]. Students who have specificlearning styles that favor physical experimentation and real-world experience are also left at

This state-ment is made in comparison to the opportunities made possible with remote labs. Consideringthat remote labs are represented as equipment that can solve location, time and capacity con-straints in laboratory education, this is surprising as many educational institutions suffer fromexactly such constraints. Existing literature shows that classroom laboratory solutions aremainly stand-alone solutions which require physical equipment and cannot be used synchro-nously among several institutions [1], [2], [3].

Thishas presented a challenge, as we currently only offer a single "Electromagnetic EnergyConversion" course, which is in a lecture format with a required associated laboratory section.To address this challenge, we have been systematically phasing out older topics, i.e., D.C.motors, and adding course content relevant to photovoltaics and wind energy production, i.e.,microgrids [1].
