This portrait of Sun Yat-sen (孫中山 / Sūn Zhōngshān) was taken from the obverse side of a circulated 50 NT coin minted in 2005. The 28 mm wide coin was first minted in 2002 by the Central Mint of China (中央造幣廠) in Taiwan and features both the Chinese and Arabic numeral 50 (五十) on the reverse side.

The Three Laws of Robotics as defined by Isaac Asimov:

1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2. A robot must obey orders given to it by human beings, except where such orders would conflict with the First Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
