Servo motor with linear output

Abstract

A rotary to linear converter in a remotely controlled toy environment for translating the bidirectional rotation of a servo motor into the linear displacement of a tab connection point. A single spool member which is driven to rotate incrementally from one angular position to another, and a flexible, nonstretchable linkage, which is integral to the spool at one end and integral to a tab at the opposite end. During the period of rotation of the servo motor-driven spool, the integral linkage is either fed off the spool or wound onto the spool thereby traversing the linkage and the integral tab through guides in the housing and lid, which act as alignment restraints tensioning the linkage and tab to eliminate slack.
