Robot with improved transmission system
 A robot toy includes a movable arm which is constituted of alternatingly interconnected three first members and three second members. The first member has a first rotating unit for moving the adjacent second member about its longitudinal axis, and the second member has a second rotating unit for rotating the first member about an axis perpendicular to the longitudinal axis. The transmission system for transmitting the output motion of a motor to the arm includes a plurality of transmission cords which are made of metal wires twisted together for the transmission along long transmission lines.
