Solution Overview
Problem
Existing cargo transportation methods, such as drones and Cargo Unmanned Aerial Systems, face inefficiencies in handling and transporting medium-sized cargoes with arbitrary shapes, particularly in loading and unloading operations.
Innovation Solution
A transporting robot with a main body, support frames, rotatable legs, and wheels, equipped with motors and in-wheel motors for autonomous movement, and a fastening mechanism for securing containers, allowing for stable positioning and efficient stacking and transportation of cargo.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If drones and Cargo Unmanned Aerial Systems are used to transport medium-sized cargoes, then transportation capability is improved, but handling efficiency and loading/unloading speed deteriorate
Solution Approach 1:
The transporting robot is equipped with autonomous navigation capabilities and self-controlled movable legs, enabling it to independently navigate to cargo locations, adjust its position, and perform loading/unloading operations without requiring external control or assistance, thereby improving handling efficiency
Solution Approach 2:
The robot employs movable legs with adjustable positions (first position for stability, second position for stacking, third position for height adjustment) that can dynamically adapt to different operational requirements, enabling efficient cargo handling and stacking operations
2Adaptability or versatility
If cargo is transported using aircraft with containers, then transportation versatility is improved, but loading and unloading time increases
Solution Approach 1:
The robot can perform preliminary positioning and preparation actions before cargo loading, such as navigating to the cargo location, adjusting its leg positions in advance, and preparing the stacking configuration, thereby reducing the actual loading and unloading time
Solution Approach 2:
The transporting system is divided into modular components including the robot body, movable legs, and stackable containers, allowing independent optimization of each component and enabling rapid assembly/disassembly operations that reduce loading/unloading time
3Stability of the object's composition
If the robot uses fixed leg positions, then structural stability is improved, but adaptability to different terrains and stacking operations deteriorates
Solution Approach 1:
The robot employs movable legs that can dynamically adjust their positions between a first position (below the main body) for stable ground operation and a second position (outside the main body) for stacking operations, allowing the robot to maintain stability while adapting to different terrains and operational requirements

AI summary
A transporting robot is utilized for rapid and efficient logistics and transportation. The transporting robot includes a main body having a flat upper surface, support frames that are respectively provided on both sides of the main body, extend downwardly, and define a predetermined angle with respect to the upper surface of the main body, a leg rotatably installed on the support frame, and a wheel installed at an end of the leg. The leg is configured to be folded below the main body, raised toward the main body, or unfolded outside of the main body.
