IoT Based Fish Food Dispenser

Internet of things and Automation are two eyes that change the view of industries perspective. Automation happens in every part of the stage in day to day life. The problem statement chosen in this paper was identified during COVID pandemic situation. The problem statement was to feed the fish food into fish aquarium at work place during COVID pandemic. In order to maintain the fish tank properly it should be monitored and maintained at regular interval is necessary. During pandemic situation felt difficult in proper maintenance and feeding the fish. To overcome the difficulties, we have proposed a model to feed the food for fish. In this paper we have solved the problem by using Internet of Things, servo motor, Arduino and interfaced through Massachusetts institute of Technology (MIT) App inventor to control the device at any part of the world. © 2023 IEEE.

Learning Efficacy and Effect of Scaffolding in Online Engineering Education during COVID-19 Pandemic

We explore the challenges of teaching "hardware-embedded Robotic Operating System (ROS) skills" online in a lockdown situation to participants through a hands-on competition. Teamwork is a vital skill in solving modern engineering problems. During Covid-19 lockdown situations, the interaction between teammates significantly reduced compared to regular times. This prompted us to design an engineering problem statement with scaffolding that improves engineering education learning efficacy. A total of 465 teams (1860 participants) were introduced to a problem statement comprising of a autonomous robot navigation, manipulation and a perception task for an indoor unmanned ground vehicle. We study the performance of teams based on several factors such as participant's score, task's difficulty level, number of resources given and the nature of online sessions by instructors. We found the scaffolding approach helped teams in implementing a solution by exploring alternative methods and thus their knowledge. © ISLS.

Teaching complex skills through an online robotics competition during Covid-19 pandemic

As the hands-on engineering education got severely affected by the lockdown due to the COVID-19 pandemic, the present study discusses how to adopt the Project-Based Learning (PBL) approach to teach complex engineering concepts in this tough time. In this paper, we have discussed the design of a gamified problem statement (using a robotic simulation environment called CoppeliaSim) which was used to teach complex engineering concepts like image processing, control systems, path planning, etc to undergraduate students by a pioneering initiative in engineering education. The study was implemented on 469 teams (1876 students) and explores how the use of a simulation environment impacts the overall performance of teams in completing the assigned problem statement. In addition to this, we have demonstrated the use of a leaderboard to increase learner engagement and motivation in completing the problem statement. Our work is useful to anyone seeking to use PBL to teach and/or learn complex engineering concepts. © 2022 IEEE.
