Abstract
Abstract 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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
218 words
A robot toy including a body incorporating a movable arm operated by a motor through a transmission system, and the improvements wherein the movable arm is constituted of alternatingly interconnected first members and second members, each said first member having a first end, a second end and a first rotating unit, each said second member having a third end for connection with said first end and said first rotating unit which rotates said second member about the longitudinal axis of said first member, a fourth end for connection with said second end of the next first member, and a second rotating unit for rotating said next first member about an axis perpendicular to said longitudinal axis, and said transmission system includes first gear members separately mounted in said robot body and driven by said motor simultaneously, second gear members for meshing with said first gear members respectively, clutch members for engaging and disengaging said first and second gear members, and a plurality of transmitting cords which are made of metal wires twisted together each of said cords is interconnected to a different one of said second gear members and one of said first and second rotating units for transmitting the movements of its respective second gear member to its respective one of said first and second roating units.
Claim 2
Dependent Claim
