Detachable Mobile End-Effector for Extended Robotic Arm Reach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operational limitations of robotic arms restrict the range of motion and functionality of their end-effectors, limiting their ability to access and interact with objects beyond their reach or perform tasks independently.
Innovation Solution
A detachable and mobile robotic end-effector system that includes a position detector, locomotion device, and control system, allowing it to operate independently of the robotic arm, with options for wired or wireless communication and a power source, enabling it to inspect, modify, or move around objects in ways the arm cannot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the end-effector is attached to the robotic arm, then the robotic arm can perform operations, but the range of motion and functionality are limited by the robotic arm's operational limitations
Solution Approach 1:
The system is divided into separate functional modules: the robotic arm for positioning and the detachable end-effector for operation. The end-effector can be detached from the robotic arm, allowing it to be repositioned independently via a mobile platform, thereby resolving the limitation of fixed attachment while maintaining system manageability through modular design
Solution Approach 2:
A mobile platform serves as an intermediary between the robotic arm and the end-effector. The end-effector attaches to the mobile platform rather than directly to the robotic arm, enabling independent movement and positioning of the end-effector while maintaining communication and control links through the platform
2Length of moving object
If the end-effector is detachable and mobile, then the operational range is increased, but the device complexity increases
Solution Approach 1:
The mobile platform is designed as a universal base that can support different end-effectors and perform multiple functions including positioning, communication, and power transmission. This multi-functional design increases operational range while minimizing the increase in overall system complexity by consolidating functions into a single platform structure
Solution Approach 2:
The system replaces direct mechanical attachment with wireless or cable-based communication and power transmission through the mobile platform. This substitution reduces mechanical complexity while enabling greater freedom of movement and extended operational range for the end-effector
3Adaptability or versatility
If the end-effector operates independently, then the versatility is improved, but the control and communication complexity increases
Solution Approach 1:
The mobile platform incorporates sensors and communication systems that provide feedback to the control system about the end-effector's position and status. This feedback mechanism enables independent operation of the end-effector while simplifying control through automated position tracking and coordination, reducing the manual control complexity

AI summary
A robotic system includes a robotic arm, a robotic end-effector detachably coupled to the robotic arm, and a control system. The robotic end-effector includes a locomotion device to move the robotic end-effector independent of the robotic arm, and the control system configured to control the robotic arm and the robotic end-effector to detach and attach the robotic arm and the robotic end-effector.
