Robotic End Effector Channel for Container Latch Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robotic end effectors with two-jaw parallel grippers are inadequate for opening and closing storage containers with stamped sheet metal latches, making automation of container inspection impractical or excessively costly, as they cannot effectively manipulate the latches.
Innovation Solution
An end effector for a robotic arm featuring a grasping apparatus with finger-type and thumb-type gripping members and extendable appendages forming a channel to receive and manipulate container latches, allowing for leverage to open and close containers, with optional sensors and lights for enhanced positioning and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional two-jaw parallel grippers are used on robotic arms, then the robotic system maintains simple structure and ease of operation, but the ability to manipulate container latches and open/close containers is insufficient
Solution Approach 1:
The end effector is divided into multiple independent gripping members (first gripping member, second gripping member, third gripping member) that can move independently. Each gripping member can be positioned and oriented separately to engage with different parts of the container latch mechanism, enabling complex manipulation tasks while maintaining modular simplicity
Solution Approach 2:
The invention transitions from traditional two-jaw parallel gripping to a multi-dimensional gripping configuration with three or more gripping members that can move in multiple directions and orientations. This dimensional expansion allows the end effector to engage with latches from multiple angles and apply forces in different directions simultaneously
2Adaptability or versatility
If containers are redesigned to be workable with current robotic end effectors, then compatibility with existing robotic systems is improved, but manufacturing costs increase significantly
Solution Approach 1:
The end effector is designed with multiple gripping members that can adapt to various latch types and container configurations. The system can handle different container sizes, latch positions, and opening mechanisms using the same robotic arm and end effector, eliminating the need for container redesign while maintaining broad compatibility
Solution Approach 2:
The gripping members are equipped with adjustable parameters including position, orientation, and movement range. These parameters can be dynamically modified through programming and control systems to match different container and latch configurations, providing versatility without physical redesign
3Ease of operation
If the end effector uses multiple gripping members with extendable appendages, then the ability to form channels and manipulate latches is improved, but the device complexity and number of components increases
Solution Approach 1:
The end effector employs a nested configuration where appendages are integrated into or extend from the gripping members. The appendages can be retracted into the gripping members when not in use, creating a compact form factor while providing extended reach and channel-forming capability when needed
Solution Approach 2:
The gripping members and appendages are designed with dynamic movement capabilities, allowing them to extend, retract, rotate, and position themselves as needed for different manipulation tasks. This dynamic behavior enables the system to perform complex latch operations with a relatively simple base structure
Data Source
AI summary
An end effector for a robotic arm is disclosed. The end effector includes a grasping apparatus having a gripping member and an appendage extending from the gripping member forming a channel between the griping member and the appendage. The channel is configured to receive at least a portion of an article, such as a latch for a container, to be manipulated by the end effector.
