Robotic/animatronic skin system with elastomeric mechanical linkages.

Abstract

A skin or skin system for a robot or robotics assembly is provided that includes one or more integral elastomeric links (or bars) ('IELs') that are configured for receiving and connection with coupling elements or members (e.g., pivot pins) at the ends of mechanical links/bars. The IELs are also configured to act as a final link of a mechanical linkage made up of these mechanical links to provide a closed chain. For example, the body of each of the IELs, or a portion of the IEL body extending between connection points with the coupling elements of the links/bars of the mechanical linkage, provides a final link in a mechanical linkage forming a closed chain to allow it properly function.

Background

BACKGROUND 1. Field of the Description (1) The present description relates, in general, to designs for creating realistic skin or skin systems for robots or for use with robotics or other applications in which skin or similar coverings are applied (e.g., robotics used to simulate movement of a human's or a character's face, hands, or other body parts). More particularly, the description is directed to skin systems or skins for applying over robotics (and fabrication methods and completed robots/robotics devices with such skins) that facilitate connection of the skin systems/skins to robotic actuators or drivers and particularly to coupling members (e.g., pivot pins) at the ends of links/bars of mechanical linkages of the robotics (or its drivers or actuators) used to drive or animate the skin systems/skins. Preferably, the new skin systems/skins are designed to enhance durability of the skin systems/skins while also providing more realistic skin movements such as facial expressions or movement while the character is 'speaking' (e.g., providing natural lip, mouth, and surrounding facial feature movement when a robotic head is operated to simulate speaking). 2. Relevant Background (2) Durable materials that are often also flexible and elastic such as plastics and rubbers are used in many applications to create coverings or skins that are applied over an internal physical support structure or skeleton. For example, skins or skin systems are used to create realistic models of hum
