This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,188.

Summary of the Inventive Concept

The present inventive concept discloses the adaptation of articulation assemblies, originally designed for surgical instruments, to various robotic applications, including agriculture, search and rescue, warehousing, environmental monitoring, and underwater exploration.

Background and Problem Solved

The original patent addressed the need for improved articulation in surgical instruments. However, the same core technology can be applied to other industries, where robotic systems require flexible and precise movement. The present inventive concept solves the problem of limited articulation in robotic systems by leveraging the wrist assembly design from the original patent.

Detailed Description of the Inventive Concept

The inventive concept comprises a wrist assembly moveably connecting an end effector to a robotic arm or system. The wrist assembly includes a first outer link, a second outer link, and a first inner link. The first outer link and second outer link are movably coupled to the robotic arm or system, while the first inner link is movably coupled to the end effector. The wrist assembly enables flexible and precise movement of the end effector, allowing the robotic system to navigate complex environments and perform tasks with increased dexterity. The drive mechanism extending through the wrist assembly can be configured for operation by various robotic systems, including those used in agriculture, search and rescue, warehousing, environmental monitoring, and underwater exploration.

Novelty and Inventive Step

The inventive concept's novelty lies in the adaptation of the wrist assembly design from surgical instruments to robotic applications. The inventive step is the recognition of the potential for this technology to be applied to other industries, where the need for flexible and precise movement is critical.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include variations in the wrist assembly's link design, materials, or drive mechanisms. Additionally, the end effector could be modified to accommodate different tasks or environments, such as grasping objects in warehousing or collecting environmental samples.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including agriculture, search and rescue, warehousing, environmental monitoring, and underwater exploration. The ability to provide robotic systems with flexible and precise movement can increase efficiency, reduce costs, and improve safety in these industries.

Field of Art

Robotic and surgical instrument design, focusing on articulation mechanisms for end effectors, with expertise in mechanical engineering, biomechanical design, and robotic system integration

Person of Ordinary Skill (PHOSITA) Profile

A mechanical engineer with advanced degrees and 5-7 years of experience in robotic system design, familiar with articulation mechanisms, drive systems, and cross-domain technology adaptation

Obviousness Rationale

A PHOSITA would recognize that the fundamental articulation assembly design from surgical instruments can be readily adapted to other robotic applications by substituting domain-specific end effectors while maintaining the core wrist assembly mechanical structure. The modular nature of the articulation mechanism inherently suggests broad applicability across different robotic platforms. The technical principles of precise movement and flexible joint design are universally valuable across multiple technical domains.
