Load Carrier Leg Structure for Wide Robot Under-Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous mobile robots are limited by their width, preventing them from entering under load carriers with legs wider than the robot's width, necessitating the use of specialized robots with narrower designs.
Innovation Solution
The implementation of U-shaped members on the load carrier's bottom surface allows autonomous mobile robots with larger widths to enter and maneuver underneath, enhancing flexibility in robot selection and enabling stable conveyance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a robot enters under a load carrier for conveyance, then the conveyance function is achieved, but the robot width must be smaller than the distance between the legs of the load carrier, limiting robot selection flexibility
Solution Approach 1:
The load carrier's leg structure is segmented into multiple components including U-shaped members and leg parts that can be independently configured. This segmentation allows the space between legs to be effectively expanded or adjusted, enabling robots of various widths to enter and perform conveyance operations without being constrained by a fixed narrow opening.
2Adaptability or versatility
If the robot width is increased to improve task capability, then the robot can perform more complex conveyance tasks, but the robot cannot enter under the load carrier due to width constraints
Solution Approach 1:
The leg parts and U-shaped members are designed with dynamic adjustment capabilities, allowing the effective opening width to be modified based on the robot's dimensions. This dynamic configuration enables larger robots to enter the load carrier while maintaining structural integrity and proper support during conveyance operations.
3Measurement precision
If sensors are positioned on the robot body for detection, then the detection function is achieved, but the load carrier blocks the sensor view creating blind spots
Solution Approach 1:
A plate structure is introduced as an intermediary component that extends the robot's sensor positioning capabilities. The plate allows sensors to be mounted at extended positions that protrude beyond the load carrier's obstruction zone, maintaining unobstructed detection fields while the robot operates underneath the load carrier.

AI summary
An automated conveyance system that enables an autonomous mobile robot having a width larger than a distance between the legs of a load carrier to enter under the load carrier is provided. The automated conveyance system is an automated conveyance system for conveying a load carrier by an autonomous mobile robot entering below the load carrier, in which the load carrier includes a plurality of leg parts on sides of a bottom surface thereof, and at least one of the plurality of leg parts includes a U-shaped member, and the U-shaped member is disposed so that two end parts of the U-shaped member on an opening side thereof are arranged in a vertical direction.
