Project-Based Learning プロジェクト ベースト ラーニング

What is PBL?

Project-Based Learning (PBL)

Project-based learning is offered in the “Flying Robot Project”, a part of “Creative Engineering Projects”. Junior and senior undergraduate students, as well as graduate students are welcome to join the project. An important goal of the project is to offer a chance to students to put in practice the knowledge they have gained in lectures to build and test their own aircraft. Following a PDCA (plan-do-check-act) cycle, the students analyze and solve an assignment, and validate their answer. During the aircraft building and flight test phases, the students work in teams, where discussions about the progress of each task helps the students develop their leadership, management and organizational skills.

PBLとは

プロジェクト・ベースト・ラーニング(PBL)

「創造的ものづくりプロジェクト」・「創造性工学プロジェクト」で開講している「飛行ロボットプロジェクト」においてプロジェクト・ベースト・ラーニングを実施します。

このプロジェクトでは、大学３年生以上大学院生を対象として、講義などで培った知識を、飛行ロボットの製作と飛行試験を通じて実践的に身につけることを目指します。その中では、与えられた課題を分析して解を見つけ、それを検証するというPDCAサイクルの体験をします。製作と飛行試験はチーム単位で実施するために、プロジェクト進行におけるディスカッションを必要とし、リーダーシップやマネージメント、役割分担の能力を高めることにつなげて行きます。

    This week, the group continued to work on the main wings and stabilisers as per usual. The members in charge of the main wings focused on creating the ailerons, while the rest of the team applied some finishing touches to the horizontal and vertical stabilisers. The manufacturing process of the ailerons were very similar to that of the main wings, whereby laser-cut aerofoils were superglued to a thin sheet of balsa wood at predetermined intervals, and a stick of balsa wood was glued along the leading edge of the aileron for added structural support. As no hinges were made for the ailerons, it was decided that they would either be taped or sewn onto the main wings.

    Last week, significant weaknesses had been identified in the central support structures that connect the main wings to the fuselage, which could lead to catastrophic mechanical failure. To address this issue, the team brainstormed several options to improve the structural stability and durability of the aircraft, such as using suspension cables for extra support, making the central supports out of stronger material and improving the overall structural design of the supports, among others. The team had ultimately opted for improving the design and material quality of the central support structures.

    Additional design flaws in the ailerons and stabilisers were pointed out by faculty and TAs, which the team decided to address at a later stage as most of the fixes could be retrofitted relatively easily. Some of the members decided to meetup again later in the week to finish off assembling the ailerons and to cut out the redesigned central support structures.

    Work on the wheels, the battery and servo motor holders, and wiring will commence next week. The team is hoping to have most of the work done by the first flight test.

    I am Yuito Izumi, a first-year student in the College of Liberal Arts, Science I, and I am in charge of this week's blog post on the airplane project. I joined this project because it brought back memories of flying toy radio-controlled airplanes in my childhood, and I thought it would be fun to start building one myself this time.
    What I did in class this week was to cut out the missing parts of the main wing. Since the available balsa board was very depleted, Senoo carefully considered the placement of the parts on the balsa when printing. Thanks to his efforts, we managed to cut out all the parts. We also learned this week the necessity of temporary assembly. The TA taught us to assemble without gluing once before gluing and assembling, in anticipation of what would happen if we misplaced a part or a part was defective. And as he predicted, there were discrepancies among the members in the placement of the parts. I am so glad that I noticed it before gluing.
    Despite these problems, we were able to tentatively assemble the entire main wing at the end of the class. The wing was much larger and more authentic than we had imagined, and we felt a kind of sense of accomplishment. Next week, we will be printing the base for the motors, designing the electrical system, and discussing the payload mechanism. We don't have much time before the end of the class. We want to pace ourselves and work on our projects.

    This week we mainly connected electrical devices with conductors. We bundled several conductors with clips and then soldered them together. The most difficult part of this work was joining the four motors' conductors into a single strand. 5 conductors were to be connected, so it was difficult to ensure that all the conductors were connected. After the connections were made, the wires were covered with heat-shrinkable plastic to insulate the surface. This week we also worked on fixing the motor to the stand. The motor was pre-drilled with a wimble and fixed to the stand with wood screws. You can see in the photo just the holes being drilled with a drill. By this week, almost all the electrical equipment had been connected and other parts installed.
    Next week, we will continue with the assembly of the drone, which has a little bit left to do. We also hope to configure the PIXHAWK controller and learn about flight systems.

    This week Group A continued to work on the main wing and tail wing at the same time as last week. At the end of last week, we decided to cover the main wings with boards, so this week we started attaching the boards. The boards were cut in such a way that the main wing could be covered with as few boards as possible. After cutting one wing, we copied the shape of the boards before gluing them and glued them to the other wing at the same time. After temporarily fixing the board with masking tape when pasting it, I first attached it while holding it down so that there would be no gap between the ribs, etc., and the board. Then, masking tape was applied to the joints between the boards from the front, and glue was poured into the joints from the back to glue the boards together. Finally, the masking tape was removed. Both wings were glued in time. Finally, we checked the connection with the carbon pipe of the fuselage and confirmed that the strength of the connection needed to be increased. As for the tail fins, we proceeded to attach the film to the horizontal and vertical tail fins. The vertical and horizontal tail fins are almost in shape. Next week, we will attach the film to the main wings and create the ailerons. By attaching the film, we will further increase the strength of the main wings. We will also think about the placement of the servo motors that move the ailerons. We will also consider how to increase the strength of the connection with the carbon pipe in the fuselage. We will continue to work on the tail wing. We hope to have most of the wing completed by next week.

    This week we connected the PIXHAWK controller to the receiver and motors using the electronic speed controller (ESC). We soldered them together. Then, we tried to understand the working of the battery and the circuit through diagrams.
    The quadcopter body and motors are arranged in the QUAD X configuration.
    Next week we plan to fix the motors and wiring.
