It was invented in the 1970s by a retired Boeing engineer as a gift for his grandson, using a tractor seat for the prototype toy. The vehicle consists of an injection-molded, polyethylene seat with rear wheels, attached to a T-style handlebar by a pin joint. The handlebars also have wheels, attached to what would be the vertical portion of the "T". In the 1980s the Roller Racer was sold under the WHAM-O brand name, but has been manufactured by Mason Corporation for three decades . The method of propulsion is unique to this scooter. The user moves forward by oscillating the handlebars from side to side. Published studies in Experimental Non-Linear Physics have been conducted worldwide on this product. It is used in amusement parks, schools, day care centers, family fun centers and homes. 〔"Oscillations, SE(2)-snakes and motion control: a study of the Roller Racer"http://www.isr.umd.edu/~krishna/images/DynSyst_RR.pdf〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Roller racer」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
