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.

    We are still working on the gravity center adjustment device (GCAD). The main parts of GCAD were made and assembled, but 3 new problems came out as:
    1) The weight of GCAD could decline too low if the thread was not tense enough while keeping the thread tense is really hard.
    2) The thread is prone to fall out of the pulley.
    3) The length of the thread is unable to be adjusted once settled down.

    In order to solve these problems, several major changes were made to the design.
    1) A long stick is used to support the weight. The thread is connected to the stick instead of to the weight, which means that the connection is shortened. It would help to keep the weight in a stable position with less effort.
    2) Cable ties are applied to join the thread and make it flexible to change the length because cable ties could be easily increased. As well, it could be very easy to make the thread tense by fastening cable ties.

    With these solutions, we will continue to make more progress.

    We couldn’t finish soldering in the last time, so we continued doing it in this time.

    Basically, what we are doing now is almost as same as the thing that we were doing in the last time, but today we are making some parts that connects frames of the multicopter.

    We are getting accustomed using CAD tools such like Fusion 360, so the speed of our development is faster than before, we suppose.

    We’ve just finished soldering and making parts by laser cutter.
    We are going to assemble the multicopter in the next class.

    Today, our team continued to product the drone part.
    The size of the drone was a relatively large 70 cm square, so the wiring had to be longer than that of the initial condition. Therefore, we extended the cable in the same way as last week. And finally, the wiring part was completed. Next, we assembled carbon pipes to make a drone frame, and in order to connect the carbon pipes in the corners of the square, we constructed the parts of plywood. And we planned to use 4 carbon pipes assembled in a square shape and 1 through the center. But considering the propeller stability, we decided to use two more carbon pipes for the diagonal of the square. In addition, the drone needs feet when landing, so we cut the excess carbon pipes and made some holes on the plywoods to attach them.
    The next week, the drone will be completed. We hope it flies without any problems.

    Hello, We are team E
    Because I intended to do a flight test this time,I installed the all equipment on the aircraft. Picture shows full equipped plane.We put the plane's throttle a max but our plane SKHQ didn't run straight and he couldn't get enough speed to take off.It is clear that legs caused this problem.We made legs by hand bent wire but hand bending was difficult to realize ideal design.After this mistake, we decided to make leg by laser cut wood parts.We worried thin wood parts strength and We strengthen wood parts by stacking.This solution also cause more work process.Full equipped SKHQ has about 250 g so completed SKHQ may has 300 g.This is good news to us. We predicted more heavy plane.After ladder and modified leg setting, we want to try flight test.Because we need more time to making leg, we will do flight test at July.

    In today’s class, we attached two servos for rudders to wing tips and attached landing gears to the fuselage pole.
    The servos for rudders are used to move the rudders which are connected to the vertical stabilizers. The left servo and the right servo work in conjunction with each other. We bonded piano wire to the rotating parts of the servos so that piano wire connects each rudder to each servo. We also attached the servos itself to the ribs of the wing tips.
    Next, we attached landing gears. This aircraft has conventional landing gear, that is, has two front wheels and one tail wheel. We attached shock struts which connect wheels and fuselage pole. Shock struts are attached to the fuselage pole by engaging veneer parts. We also attached supporting struts in front and back of the shock struts.

    A teaching assistant pointed out our two mistakes.
    First, the connecting point of the servos and the rudders should be around hinges.
    Second, too much stiffness of the shock struts may break the aircraft during landing.
    We’ll make use of this advice when we make unit 2.

    In the next day, attaching front wheels is completed and the aircraft is ready for test flight. Although I wonder we can trim this aircraft, we’ll try test flight anyway.
