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。

    From today, we started to code our programs for controlling the aircraft. Since we decided to utilize quaternions to control the aircraft, we started by implementing a class for quaternions. We will be coding the programs with the C programming language, and this was the first time that I tried implementing a new feature to the C programming language. Therefore, I made the program while studying how to make a new program at the same time. By the way, the method of controlling the aircraft using quaternions is based on a research paper. In this paper, the method utilizing quaternions is applied to quadrotors, but we will be applying it to fixed-wing aircraft. According to the paper, the method using quaternions is useful because it can solve the problem such as singularity which exists in methods utilizing Euler angles and other conventional methods. Moreover, for me, this method is intuitive and easy to understand.
    For the next step, we will be trying to acquire values from the sensor, actually controlling the servo motors, and determining the parameters required for the control.

    Our group, Group A, has decided to make an all-wing aircraft. The all-wing aircraft has the complicated shape, because the main wing and the tail wing are merged. However, all of us would like to make the aircraft which has the big main wing, so we have decided this shape of the aircraft.
    In the class of this week, we continued the work as we did in the last week. Concretely, we assembled the parts. First, I connected the main wing and the fuselage. Second, I connected the body and the shaft.
    First, I will talk about the connection of the main wing and the body. I made the special parts for the connectors which let us connect the two parts firmly. Because of the large size of the wing, we had to cooperate connecting the main wing and the body. This work is very hard and difficult, but we were very impressed when we connected the main wing to the body correctly.
    Second, I will talk about the connection of the body and the shaft. We also made the special parts. This part needed a little twist in thinking so we made the hole in order to be able to pass the rod of the shaft. Therefore, assembling the parts together were difficult but that in the end created a very rigid aircraft.
    These special parts will reinforce the aircraft and the aircraft can fly stable.
    In the next week, we are going to fly the aircraft after some adjustment.
    Thank you for supporting our study every week.

    In the previous plan, we wanted to make a new drone body part slightly larger than the existing drone body part with plywood and continue to make the propeller protection part.
    In the actual work, focusing on the work of the microcomputer (Pixracer), we assembled the drone body part on the plywood and assembled it to produce the propeller protection part. The details are described below.
    On the microcontroller side, software QGC has been used to set the model type, compass calibration, flight mode, and other parameters. For the radio, we created an account and checked the switch of the arm and which stick was used as the rudder.
    As for the drone body, a revised version of the drone body previously made using plywood was printed with a laser cutter. After that, the soldering of the motor and the connector was completed three times, and it was confirmed that each motor turned from the signal from the radio using a 2-cell revolver. However, the fourth motor has not been made because the metal parts of the connector were missing. In addition, we confirmed which direction each of the four motors of the multicopter should rotate.
    Regarding the production of the propeller protection part, finishing touches were made on the joints.
    This is the end of the official work, but we hope to get together and do some final assembly and test flights in the future.

    Our group, Group A, has decided to make an all-wing aircraft. The all-wing aircraft has the complicated shape, because the main wing and the tail wing are merged. However, all of us would like to make the flying robot which has the big main wing, so we have decided this shape of the aircraft.
    In the class of this week, we continued the work as we did in the last week. We made the framework of the main wing on the blueprint which we printed out last week of it with wood and we also made the parts.
    First, I will talk about the main wing. Considering the weight, 200g, and the speed, 3m/s, we had decided the area of the main wing, 0.76m2, solving the equation of Lift. We put the wood parts which we made of the balsa on the blueprint. We have to work carefully.
    Second, I am going to the parts which connect the wing and the body, and which connect the body and the rod as axis. We used laser cutter. I moved the CAD data which shows the blueprint from my computer to the laser cutter’s computer. We cut the veneer as the blueprint shows on the computer. Veneer is more intense than balsa. So, we used it to reinforce the part which are very weak in terms of the construction. It is very interesting for me, because I have never done such operation. We also made the part which connects the body and the rod as axis. We also made this part, using the laser cutter.
    In the next week, we are going to assemble the flying robot.
    Thank you for supporting our study every week.
