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。

    In the last week’s activity, our team found that the strength of the structure was lacking to hold the vibrating-strong motors. It is necessary to develop more tough body, but the overall mass of the drone is limited. To develop light and strong structure, we decided to use three-dimensional structure. (see below two pictures) On other hand, our team built the software-developing-infrastructure in each computer. We are planning to develop the structure and its software at the same time.

    Hi, my name is Matsuura. I will report the progress of today’s meeting. In previous class, we discussed the structure of our plane, then, in this one week one of our team added some detail modifications to the specification. We discussed it more deeply and finally complete the specification in today’s meeting. Especially, we discussed the connection parts between the plane wings and the framework which fasten 4 motors to take off and ground. First, we planned to connect them with one vertical stick of balsa because the structure looks easy to make and was used in past successful body. However, we determined to challenge new structure. We wanted to make a different plane. Therefore, we are going to make V shaped structure under the wings by using two balsa sticks like framework of motors is hung from the wing. By using two sticks, we can spread the force out when the plane takes off and reinforce the connection. We also considered the connection parts of carbon pipe. There were some ideas, for example, using special adhesive, balsa and so on, but eventually we decided to print original joint parts by using 3D-printer to make our plane strong and stylish. It may be difficult for us to design the parts and operate the printer, but we are going to make efforts. By next class, we must make a list of materials, review the specification, print a big paper pattern, and design the joint parts with 3D-CAD. We are going to share the work, complete them and begin to build our plane in next class. Through today’s meeting, we made progress and were greatly motivated to perfect our plane while we found there are many things to be considered as we discuss in detail. We continue to make effort.

    Based on the meeting about the design of our model, we have created the model with CAD software by the beginning of this class. In the class, we learned how to use the laser cutter and actually made the model with it. It worked better than I expected even when cutting complex parts. The created model didn’t seem to be tough, so we discussed how to reinforce the multicopter. We also talked about the required components considering their restrictions. All of the discussion has not been concluded yet but we are going to elaborate them by next week. Finally, we divided ourselves into 2 teams; Structure team and software team. I will be involved in the software team so I am going to study a microcontroller called Pixracer and try it in the next class. Our work has just started but I cannot wait to experience how it will go.

    This week, we specifically designed the folding and unfolding mechanism of the airframe. After intensive discussion, aluminum was adopted as the material for the spars and the body because it is relatively light and easy to mold. Though aluminum is one of the lightest metals, it weighs more compared to other non-metal materials like balsa wood and CFRP. Therefore, reducing the mass of aluminum used for our aircraft is an important demand. So in this design, the volume of aluminum used in airframe is minimized. Since the basic structural design was fixed, we are planning to start processing from next week. For this sake, we ordered aluminum angles and other materials like carbon rods. We have a plan to use 3D printer effectively to improve precision of processing. After processing, we are going to have a flight test by manned operation on March 13. Though it is quite challenging to process an aircraft within a week, we are going to challenge it.

    This time we discussed the specific structure of the plane. It was necessary to change some points from the first idea. The main wing’s structure was determined to semi-monocoque, making much of the strength. So we changed the wings from delta wings to trapezoidal wings for ease of building it. In addition, it seems to be suitable for inverted flight to use symmetrical wings. Because of this, our plane’s nose have to look upward a little to obtain lift when it flies. Also, we increased the size of the wing’s area in accordance with the weight of semi-monocoque structure. Finally, we expected our plane to fly at a speed of 5 meters per second, weigh 250 grams, and the size of the main wing’s area is about 0.26 square meters, two times as big as the first idea. We decided to use a horizontal stabilizer which can turn itself because we thought it would give our plane nice controllability. But there seems to be still some room for consideration about this structure. For example, one axis on which the whole horizontal stabilizer turns has to support the weight of it and it is easy to break. We have to devise some methods to reinforce the tail. As for vertical tail, we decided to set rudder under part of which is cut because horizontal tail will turn. By next time, we will make these parts of our plane on our computers using CAD, assemble them and calculate the lifting power on each part. Next week, we are going to start tomato our plane at last.
