兒童程式設計

In September 20th Lego Mindstorms EV3 Robotics class, Kids learned how to calibrate the sensors on the robots and how to code using "my blocks."

In this week's coding class, Owen and Jas worked hard trying to debug their spinner robot. It worked great _sometimes_! But they kept running into alignment issues.

In coding class today, the kids continued to build the massive Spinner Factory robot. But today I introduced them to a simple Kanban board to keep track of what was built. The instructions include 465 steps.

Over the weekend Mr. John saw a video from a young woman who studies robotics. Her advice on how to learn robotics was to tear things apart and then put them back together.

In coding class we finished the code for the ellaphants we built. The kids made a program that would use the robot keypad buttons to control what it did. Up button to make the elephant walk forward. Down button for backward. Left button for head tilt and trunk trumpeting. And right button for picking up an object.

For these two weeks, kids worked on an elephant robot. It is supposed to walk without wheels.

First week progress:

For this week's morning and afternoon closing class. We created animations for a space ship and floating monkeys. The kids learned to use loops and how to change the Sprite over time.

In today's coding class we started on a motorcycle robot. It will use the gyroscopic sensor to keep itself balanced on 2 wheels.  All they had for instructions was a video showing a working Lego motorcycle. No build instructions and no programming instructions.

今天的兩堂Code Club在孩子們的不捨回家當中結束，雖然今天最重要的事就是把帳號建立好，所有學員互相追蹤，加上開始讓一隻貓滾來滾去，又忙碌，又混亂，又好玩的一堂課!雖然孩子們之間的英文程度有些較好，有些還在起步，可是大家都很勇於發問，沒有因為要跟Mr. John溝通而不敢問問題或是不願意學習。搭家的學西精神都好好喔!

The coding class finished programming their recent robot. They learned how to have multiple threads of program execution and how to interrupt one thread from another and how to use global variables as flags to send quick messages across threads.

利用multiple threads和program execution, 機器狗終於完成了!
