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.

    2019 Autumn Semester Flying Robot Project Team F Article 1

    We are taking this course again to complete building Sierra, the plane we are making since the last semester. Our first and second Sierra plane didn’t fly as we’d expected, mostly because of our lack of experience in creating the auto-pilot program and systems. In this semester, we are going to improve the circuit board and program. Also the aircraft itself has been redesigned. We worked on the third Sierra on the first week and it’s almost completed as you can see in the attached picture. Next week we’ll look into the old circuit board we made to find what was wrong with it and how to fix the problems.

    Making the Flying Robot report
    Group A, Takumi Endo, November 5

    Our group, Group A, has decided to make an all-wing aircraft. The all-wing aircraft has a complicated shape, because the main wing and the tail wing are merged together. However, all of us would like to make the flying robot which has one big main wing, so we have decided on making a aircraft of this shape.

    All of the members of Group A are the bachelors 1st grade student. So, we are very nervous on completing the aircraft, but we are trying to get over the obstacle with the help of Teacher's Assistants.
    In this week, we completed three things. First, deciding the role of each member, second, deciding the aircraft shape in detail and third, deciding the material of the framework. I will introduce each thing briefly.

    First, I will talk about the role of each member. We have five positions and they are the person who draws the blueprint, the person who creates a CAD model based on the blueprints, the person who decides the motor, the person who decides the servo and the person who decides the position of various items. Each member holds one position.

    Second, I will introduce the shape of the aircraft. Considering the weight, 200g, and the speed, 3m/s, we have decided the area of the main wing, 0.76m^2. In addition, we simulated the shape with the paper plane in order to imagine how the aircraft will fly. Third, we are going to use the balsa wood with a thickness of 3mm and whose width is 10mm and use this vertically in order to increase rigidity.

    Thank you for supporting our study.

    2019 Autumn Semester Flying Robot Project Team D Article 1

    Hello, I'm Masaya Ido, from group D of flying robot project 2019autumn. We are going to build an autopilot airplane aiming to participate in the next Indoor Flying Robot Contest in 2020.
    While three members are engaging in designing and crafting the airplane body, the other two are developing an autopilot system. There are three Bachelor 1st year students, one Masters 1st year student (me) and one Masters 2nd year student in our team. My background is aerospace engineering.
    The design of our plane is truly orthodox, with a large tough wing and ailerons. This is because an autopilot airplane should fly slow and steady. The wing area is estimated about 6000cm^2 and it is designed to fly at 3.5 m/s. Aileron is aimed at turning quickly.
    In today's class, we started making tail wings as shown in the photo. And I have just decided the airfoil and started designing wing structures. Next week, we are attaching the tail wing to the body and we will learn how to use the laser cutter, which is necessary to generate wing structures. Also, we are collecting electric parts such as motors, servomotors and a microcomputer in order to make a electric circuit by using these parts.
    Thank you.

    2019 Spring Semester Flying Robot Project Team E Article 9

    Hello, I'm K form team E.
    This time we made all the parts set.
    Picture shows the completed plane "SKHQ".
    At taxing test, we checked SKHQ could run straight.
    I was relieved because I personally made leg and wheel.
    It was rainy so we couldn't do flight test, but we checked the
    control surfaces.
    Right and left elevon linkage moved unbalance but was easily modifiable by controller setting.
    However, vertical wings rudder trouble was difficult to solve.
    This trouble was rudder control was not effective because the link between servo and rudder was not good.
    Reason of this trouble was that wire used for connection servo and rudder couldn't stand bending load.
    Best method was set link system to protect wire from bending but we didn't design main wing with extra space,
    so, this method was difficult to do.
    We may change our mind and do not set rudder.
    Plane can fly without rudder we know this is very extreme theory.
    Anyway, next is flight test.
    To tell the truth this blog was written one week later because I forgot writing
    Sorry for late.
    Flight test results will be show next blog!!

    2019 Spring Semester Flying Robot Project Team E Article 10

    We conducted our first flight test for our plane. We were excited that we will finally were able to see our work take to the skies... but unfortunately, the best we could achieve today was a few "hops" during taxiing, despite our best efforts to lift the plane with the eleovons. There are a several likely causes for the problem, the largest of which are the fact that the moment pushing the nose downwards are too strong, due to the aerodynamic forces and the center of gravity being at too front of the plane. There is also the fact that the front wheels are currently too unstable for gaining speed, and the point of force working on the elevons from the servos are placed at a bad place.
    We addressed all of the problems and challenged on the Second test flight on the 23th. This time, we managed to achieve a good stable flight. We crashed the plane a few times due to piloting error, but ended the day with no major damage except a broken propeller .It seemed that for airplanes with a high thrust to weight ratio, at this scale, the accuracy of the assembly is less important compared to the adjusting of Center of gravity and trims.
    Can’t wait for the next, last test flight day!
