November 1, 2018 Fighting Robots

Hello, it's Jonathan the camera guy. Today, I would like to introduce this week's activity in the Engineering Design class. You can read more about Engineering Design here. It is the course where students use design thinking and engineering skills to make things for society. This week, we are building robots using Lego Mindstorms. Lego Mindstorms is a platform for robots that can be programmed and built using Lego blocks, motors, gears, sensors, tires, etc.

This week's Engineering Design class was divided into two parts. In the first part, students were given a list of challenges to program their robot; such as "turn exactly 90 degrees", "move forward and bring back a box" or "move along a fixed path." Mindstorms has a visualized programming interface, and users can program their robot simply by connecting orders on a computer and uploading them to the robot. Students could do the challenges in any order they wished. There was much trial and error. However, students completed the challenges one by one thanks to Mindstorms' user-friendly interface.

The second part was more interactive. The goal was to build and program a robot to fight Sumo wrestling style. Students were given 45 minutes to build and program their robot. Afterwards, they would hold a single elimination tournament. Students quickly began preparing their robots for battle. Many students added weapons to the front, while some worked on reworking the tires. 45 minutes passed in no time, and many students rushed to finish up their programs. Students could not control the robots after the battle started and they had to predict and program their robots as best they could. Students completed their robots and the tournament began.

It was interesting to see the individual strategies each student came up with for exterior and movement. Some students programmed their robot to advance forward, while others took a more "clever" approach and programmed their robot to back off to the side and flank the opponent. You can see a couple of the battles in the video below. As you can see, things do not always go as planned. The robot that won the tournament looks innocent without any added weaponry. However, its secret is in the tire mechanism. The builder explained that working with the gear ratio of the motor and tires, he was able to create a robot that moves slow but powerfully. After the tournament, students gave a presentation on their robot and about what they would do differently next time.

I asked the students about the class and many answered that they enjoyed it. It was an intense schedule, but a fulfilling one. Ogawa sensei, who is in charge of the class, explained that Mindstorms is a perfect way to prepare students for more complex programming and robot building in the future. This technology can be utilized to create robots for manufacturing lines, rescue robots, etc. in the future. There is a distinct muscle in the brain for programming robots the way you wish them to move and I believe this class was a fun and effective way to tap into that field. Thanks for watching. See you next time.

こんにちは、ジョナサンです。今日は今週のエンジニアリングデザインの授業内容を紹介したいと思います。エンジニアリングデザインは学生がデザインシンキングや、ものづくりの技術を使って社会に役に立つものを作ることを学ぶ科目です。今週はLEGO Mindstormsを使ってロボットの製作をしました。LEGO Mindstormsはロボットのプラットフォームで、ブロック、モーター、ギア、センサー、車輪などを使ってロボットを組み立て、プログラミングを使って動かすことができます。
