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 we wrote aircraft blueprint with a CAD software. We got used to using the new software. We could work smoothly now. Next week we will make aircraft parts using a laser cutter.

    On November 1st, we started the session by closing out the remaining construction of the horizontal and vertical stabilizers from the previous week. This meant cutting out balsa gazettes and gluing them together to rigidify the weaker joints. The parts are not perfect, as some of the bonding surfaces where not matched precisely, but they will be sufficient for construction. A picture of the final part is shown.
    Once this was completed, the team began to think about the wing design. Specifically, we needed to decide the spar and rib configuration, dihedral angle, and wing-fuselage attachment. We drafted several ideas and discussed the merits of each. How many spars will we use and out of what material will they be made? Should the spar run through the center of the ribs or through the top edge? Should we build our leading edge out of thin balsa sheet or will a lighter paper material suffice? These were among the questions we asked ourselves. Ultimately, we decided on a carbon square tube wing spar because it is rigid, strong, and the square shape will make it easy to set our rib twist angles. The ribs will be made out of balsa sheet, and will be reinforced with crosshatched struts aft and fore of the wing spar. Lightweight paper material will be used for the wing skin because it will save weight and it will be easy to repair if the plane crashes. As for the fuselage linkage, we decided to go with a T-joint as pictured. Once again, this simple design makes it easy to set the dihedral angle, and will provide a rigid joint.
    Once these design characteristics were agreed upon, we assigned parts for each team member to draft. By next week’s meeting, we expect to have drawings of the T-joint, ribs, and spar ready to laser cut.

    This week we wrote the aircraft blueprint with a CAD software. We will make parts of the aircraft using a laser cutter. For this week, We made a part which attaches to a propeller as shown in the picture. Next week we will make other parts to print on the laser cutter.

    2017 winter semester Flying Robot Project 1st Team Business

    As a business model by using drones, I suggested a cleaning agency of windows of buildings and apartments. This is because it is done manually and it takes a lot of costs. In addition, every year the accidents that a gondola falls in cleaning and some persons are injured happen in every place in Japan, so the work is really dangerous. And more, these days the urbanization is proceeding and buildings are becoming more and more higher in the world, so it is though that it is worthwhile and effective to make use of drones and let it work instead of humans in this market. At the beginning, the project will be started by manual operation of drones as a trial, and finally it is aimed by automation and remote monitoring. In automation, after a request of cleaning is sent by a owner of a building on the Web site or telephone, a drone flies to the destination automatically using the GPS function installed in it, and the building is identified with the image recognition technology, and then, cleaning is started. the location of the drone is constantly monitored from a remote office, and the status of the work is always confirmed by the camera attached with the drone. To implement and develop this system, there are two problems at the present. One is that it is needed to get legal permissions for unmanned flight in the DID area. And the other is that a technical problem. It is necessary to create a mechanism in a drone for autonomous flight and cleaning. I will consider the details of the system in the next step.

    After spending a few weeks planning the structure of the plane, we began to actually build the frame. This week, we almost completed building the frame of the vertical stabilizer and the horizontal stabilizer, including parts for elevator and rudder.Balsa wood was used as often used for small airplanes like ours. The process did not require complex procedure so it did not take much for us to execute it, and it won’t be long until the frame is completed. It should be done next week.
    Even though we almost finished planning the structure of the plane and are now building parts of it, we still have not decided the details of the main wing. The size is already planned but we are yet to decide how it will be shaped. Main wing is one of the most important parts of an airplane so we have to think about it carefully. In addition, our plane will have ailerons on its main wing. The process may not be easy. We have to finish the job next week.
    We are in a group of four so the process is going faster than usual. Hopefully we will finish building the plane soon and spend more time on flying it.
