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.

    2023 Winter Semester Flying Robot Project Team C Article 6

    This week, group C shaped both wings and cut out the excess parts for joining. First, we worked on attaching the right-wing plank, which we did not complete last week, by attaching both the upper and lower sections, cutting off the larger-sized sections with cutters and scissors, and then smoothing the surface with sandpaper. After that, we decided to move on to the installation of the joints, but the trailing edge was distorted and not in a straight line, so we removed it from the rib and finished the work after cutting out a new rib. This rib will be installed in the next project.
    Next time, we will cut some of the ribs, re-install the ribs so that the trailing edge is not distorted, and reinforce the ribs with square wood to contact the glued portion of the ribs to increase strength. In addition to reinforcing the ribs with carbon, we would like to add additional reinforcement with thin plywood and other materials we have available, install the elbows, apply Japanese paper or vinyl to the top and bottom of the wings, and then glue the tail wing in place. Although it is a lot of work, we have already secured the materials this week and have already confirmed some of the production methods, so we would like to divide the three of us into groups and work in parallel. As for the installation of the motor, we would like to adjust the center of gravity position after the overall work is finalized. Although there is not much time left, the three of us will work together to make the plane fly at the end of the project.

    2023 Winter Semester Flying Robot Project Team D Article 5

    This week, Group D continuously proceeded with both the software and the body of the multicopter.
    As for the making of its body, we already connected the upper half and the bottom half of the multicopter the previous time. Thus, we made some preparations to attach propellers for horizontal movement in the empty space between the upper and the bottom halves. First, we attached three carbon tubes in a diagonal direction as reinforcing material and glued them. Then, we cut 5cm-square wood slabs and tightened motors with screws. We could not attach propellers to the motors, so we will do it next week. Also, we were going to attach a 297mm×184mm-wood slab diagonally and attach motors to it, but we have to review its size. This is because there is a concern about a big air resistance if such a big part exists vertically to the direction the multicopter moves.
    As for software, we made great progress including lighting the LED. We are almost done with the LED when we decide where to put it. We are still thinking about how to communicate with the multicopter. We are still wondering if we should use Wi-Fi or other means of transmitting signals.

    2023 Winter Semester Flying Robot Project Team C Article 5

    This week, Team C completed one wing and started working on the other. The first task was to connect the left and right ribs to the upper and lower spars with boards. Balsa boards were cut to match the widths, roughly matching the top and bottom widths, and then glued together, sanded and smoothed. This was done between all the ribs, which gave the wing a D shape in cross-section and made it stronger. One wing is now complete.
    Next, we set about making the other wing. The workbench was too small for two wings, so we decided to make one wing and then combine them into one. The previously cut-out ribs were fixed with masking tape on the printed blueprint and the spars were passed over all the ribs front, back, left and right. After gluing the spars and ribs together, we set about fitting the planks. When bending the planks and gluing them to the spars and ribs, the planks were wetted with a misting spray to give them a bend. The work was completed when one of the upper planks was attached.
    This was the end of the work as a class, but we will be allowed to use the workroom in the same way from next week onwards. In the next class time, we will work towards completing the wings as one piece, making the motor mounts and stretching Japanese paper or cellophane on the top and bottom of the wings. We will also be looking at increasing the strength of the spars by making additional spars as we seem to have accidentally used balsa wood for the spars this time instead of cypress wood.

    2023 Winter Semester Flying Robot Project Team D Article 4

    This week, Group D proceeded with making the multicopter itself and operating the software.
    As we almost finished making the bottom part of the multicopter the previous week, we attached balsa wood members for landing it. Then, we continued making components made of carbon tubes and wood to connect the upper half and the bottom half of the multicopter. We also managed to connect them with four carbon tubes. In the remaining time, we cut more carbon tube components.
    In regards to software, we are still at the practice stage, but we tried rotating the motor. We could not rotate it at first, but we managed to rotate it after changing the hardware. We also confirmed that the LEDs flash.
    Next time, we hope to proceed to the stage of attaching propellers for horizontal movement in terms of the body of the multicopter. We also want to handle the software in a big way.

    2023 Winter Semester Flying Robot Project Team C Article 4

    This week, Team C split into teams of two and one to install the planks and cut out the ribs on the other side.
    Last week, we fixed the cut-out ribs on the drawing, corrected the misalignment of the spars at the four points on all the ribs, and installed the planks on all the top surfaces and part of the bottom surfaces. Then, the planks were glued in place. When sanding the adhesive area, we were advised that we should not use the sandpaper alone to sand the surface, but rather stick the sandpaper to a square piece of wood and apply force from various directions to create a clean curve and reduce aerodynamic drag, which we did.
    On the other one, we started assembling the right wing and cut out the ribs with a laser cutter. Using the lessons learned so far, we added legs to all the ribs and also made notches with the laser cutter to facilitate cutting the ribs and legs. Now that all the ribs have been cut out, we would like to start aligning the ribs in the next class, but we will be careful not to destroy the ribs and feet because they are very fragile.
    The goal for the next class time is to line up the ribs on the right wing side on the drawing, pass the spars and fix them, and then attach the planks. Since the remaining time for making this project is short and there are only three members in Group C, we will work as much as possible. We also hope to add a vertical board to reinforce the center plank and revise some of the design, such as how to position the sled and motor, at the same time before joining the right and left wings.
