Solution Overview
Problem
Conventional multiarticular picking-up robots are large and cumbersome, making them difficult to transfer quickly to disaster areas and requiring significant storage space.
Innovation Solution
A compact picking-up robot design featuring a telescopic robot arm with nested arm tubes, a push chain, a sprocket, and rotary motors, allowing for up-and-down tilting and extension/contraction, which reduces the robot's size and enhances mobility and storage efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multiarticular robot arm is used, then the robot can perform complex picking operations, but the robot size increases making it difficult to transfer and store
Solution Approach 1:
The robot arm uses a telescopic structure with nested arm tubes that can fit one within another, allowing the arm to be compact when retracted and extended when needed for picking operations. This nesting principle directly reduces the robot's volume while maintaining its functional capability.
Solution Approach 2:
The robot arm transitions from a static multiarticular configuration to a dynamic telescopic structure that can change its effective length and configuration. The push chain mechanism enables dynamic extension and retraction, allowing the robot to adapt its size to operational needs while minimizing storage volume.
2Length of moving object
If a multiarticular robot arm is used, then the robot has sufficient reach and flexibility, but the transfer operation becomes complicated and time-consuming
Solution Approach 1:
The nested arm tubes allow the robot arm to be completely retracted into a compact configuration, dramatically simplifying transfer operations. The entire arm structure can be collapsed to minimal length, making the robot easy to transport and deploy without complex disassembly procedures.
Solution Approach 2:
The push chain mechanism extracts the complexity of arm extension from the transfer operation. By using a simple chain-driven telescopic system rather than multiple articulated joints, the extension and retraction functions are separated from the complex multiarticular mechanisms, leaving only simple linear motion for transfer operations.
3Adaptability or versatility
If a multiarticular robot arm is used, then the robot can handle various article positions, but the storage space requirement increases
Solution Approach 1:
The telescopic arm tubes nest within each other when not in use, reducing the robot's overall footprint to a fraction of what a conventional multiarticular arm would require. This nesting capability allows compact storage while maintaining full extension capability for handling articles at various positions during operation.
