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 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:

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.

孩子們兼天的挑戰是製造一個機車，沒有任何的參考或是說明，只有一張最後的成果圖!挺有趣的!!!

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!

In this week's coding class we discussed program threads and how Lego Mindstorms software allows kids to create multi-threaded programming.  The kids finished building the Znap robot from instructions and then started programming it with only the rough outline that was written on the board as a guide. They need to use multiple loops, variables, and a new loop interrupt instruction.

這星期我們探討了電腦程式裡的multi-threading功能，利用Lego Mindstorms的程式設計軟體，孩子們練習了multiple loops, variables, 還有 loop interrupt。
