Noise from Motor 電機的噪音

Noice from motor affects the voice sensor. Kids suggest to wrap the motor with plastic sheets, for reducinng the noice. Not a bad idea !
電機的噪音太大了罷，干擾了聲音感應器，小朋友動動腦肋用膠紙包著電機以減低聲浪，效果不俗。

Voice-Activated Car 聲控小車

We have kids to plan for and build a voice-actived car. Car moves forwards and backwards while kids shout. The wind turbine direction also changes accordingly.

這星期的工作坊和小朋友一起計劃及建造這聲控小車。小朋友叫一聲，小車向前；小朋友再叫一聲，小車向後。小風車的轉向也隨之而轉變。

Basic Flow of Robot Design 機械人的基本設計流程

1. Plan the control logic between -- e.g., motor, sensors, etc. 
先計劃控制邏輯，例如：電機、感應器等關係。

2. Write the program, download to the robot's computer. Then, design your robot outlook. 
編程，並下載於機械人的大腦。 然後設計機械人的支架、外型。

3. Fine-tune your robot's design and program, until it meets your needs.

優化編程，並美化機械人的外型。

Nixie Tube LED Display 數碼管

This kind of Nixie Tube is having 8 pins for signals tranferred to 7 strokes plus 1 decimal place on the LED display.

Google-search with its model number "5101AS" for specifications.

這類數碼管共有8針 － 7 針控制數字上的 7 橫，餘下的 1 針是給小數點。

有關硬件規格可以其產品編號号 － "5101AS" 在網上搜尋到。

"Brain" of a Robot 機械人的"大腦"

"Brain" of a robot = CPU + Harddisk + RAM
that controls the power supplies, sensors (ie. input), and motors (ie. output), of a robot,
with proper control from programs (ie. logic).

機械人的"大腦" = 中央處理器 + 硬盤 + 記憶體
以控制機械人的 能量來源，感應器 (即: 輸入)，及電機 (即: 輸出)，
並配以切適的程序  (即: 邏緝)。
