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。

    Today was the first flying test. To make the long story short, our robot did not fly. This was because of tires. Our robot is VTOL (vertical take-off and landing), so we did not think we need to make tires for the flying. However, the regulation of the motors of the multi copter was not completed yesterday, so we suddenly had to prepare tires for the test in order to test if it can take off as the same way as normal planes do. I cut balsa wood and plywood board by laser and made tires yesterday. Just before the flying test, I set up them to our robot with piano wires. It was so stiff that I thought they must hold up our robot tightly. When our turn came at the flying test, we started the motor and the plane began to run. Soon after that, it lost its balance. The piano wires could not have stand up the weight. We really wanted to see our plane flying, but we changed our mood and returned to the work room. We started the left tasks. One of us repaired the string for regulating the aileron. I fixed wiring of the multi copter with solder. Also, we reinforced the tires by fastening them to the robot directly. Finally, our robot have been completed. We worked together not only in the class but also at extra time, and tried and failed one after another. Also, many people helped us with appropriate advice. We will have the second flying test next week. We are looking forward to seeing our plane flying.

    We change its electronic central control system (ECCS) with a new one. As changing its ECCS, we simplified and rebuilt its electronic components because of its complex wiring and was difficult to do maintenance. As a result of changing its ECCS, the four motors worked properly, but its calibration wasn’t good, so we couldn’t fly this drone.

    This week, we have worked to connect the main wing, horizontal stabilizer, vertical stabilizer and solder conducting wire of the esc and motor, and the esc and microcomputer. We felt uneasy about strength of the main wing because the parts of it were attached in a very small area, but it was firmly fixed more than we expected. I realized again how reliable instant glue was (also auxiliary parts worked). The pictures are the main wing, tail wing. At this point, all the parts were completed except for the details, and the overall picture of the flying robot was visible. Combining these will bring us into the actual flight, and I'm very looking forward to this. It turned out that there was a slight misalignment of the framework of the main wing and the connecting position of the body, so we plan to attach the plywood to the framework of the main wing along with reinforcement. From now on, we need to think about how to connect fine parts such as servo and wheels. We have already got connectors and servos, so we will connect this next time. After next week, we rush into test week, and we can meet only a few times until 27th, when we will do flying test. So, we need to work together and complete it efficiently.

    This week the other wing was fitted with the same poly-carbonate sheet cover as well. The cover was applied in the same manner as the previous week, using superglue. Additionally, the rear end of the wing frame was completed. First, missing spar like frame in the rear of the wing were cut out from 2x4mm (which was fabricated from two 2x2mm) wooden stick. They were glued into place using superglue. This does not actually function as spar, as it is constructed using multiple pieces, but function to hold wing cover into place. To two of such frames was attached elevon, using string, and to two other frames were attached drag rudder also using string. The rest of wing cover was done using thinner softer, and lighter sheet of plastic. First covers were glued to the elevons and drag rudders using adhesives pre-applied on the plastic sheet. The excess sheet was then trimmed into shape. Rest of the wing was covered using sheet without adhesive, using double sided tape. The joint between poly carbonate and the thin covering material was sealed using masking tape, to prevent air from rushing in. This week, we managed to cover the entire top sides of both wings. After that, fan duct was glued to the body frame using epoxy glue. The glue was left for curing as it takes 24hours to completely cure, according to the spec sheet.

    We built the structure of the drone, and its electric components. However, one of its motors did not work properly, so we couldn’t fly our drone. Through looking at our drone, we found that its flying control system had somewhat malfunctioned. In next week, we will replace its flying control system with a new one to have four motors working properly.
