Transport Robot Load and Angle Control for Stable Cart Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport systems require modifications or attachments to transport objects, such as turntables, support rods, eyebolts, or grip mechanisms, limiting their ability to transport various types of carts or freight without reloading, especially those without pre-installed support structures.
Innovation Solution
A transport system comprising multiple robots that sandwich and stabilize the transport object using a contact part with a rotation mechanism, load sensor, and angle sensor, allowing for controlled load distribution and rotation to maintain stability during transport without modifying the object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If turntables or support structures are installed on transport objects, then transport stability is improved, but the transport object must be modified and reloading is required
Solution Approach 1:
Instead of modifying the transport object with turntables or support structures, the invention inverts the approach by equipping the transport robots with rotation mechanisms and contact parts that can actively adapt to and stabilize various transport objects without modification. The robots provide the stabilization function rather than the objects.
Solution Approach 2:
The transport robots are designed with universal contact parts and rotation mechanisms that can work with various types of transport objects (carts, dollies, platforms) without requiring object-specific modifications. This multi-functional design eliminates the need for reloading different object types.
2Quantity of substance
If multiple transport robots collaborate to transport an object, then transport capacity is improved, but coordination complexity increases
Solution Approach 1:
The invention employs feedback mechanisms where each transport robot is equipped with sensors (load sensors, angle sensors, position sensors) that continuously monitor the transport object's state and the robot's own status. This real-time feedback enables automatic coordination and load distribution among multiple robots, reducing manual intervention and simplifying control complexity.
Solution Approach 2:
The transport robots are designed with autonomous capabilities to automatically adjust their positions, loads, and coordination without external control. Each robot can independently sense the transport object's weight distribution and automatically adjust its contact force and position, enabling self-organized collaboration that reduces overall system complexity.

AI summary
A transport system transports a transport object in a state sandwiching the transport object between a plurality of transport robots, wherein the transport robot comprises: a main body; wheels; a rotation mechanism that makes a contact part rotatable relative to the main body; a drive part(s) mounted on the main body and driving the wheels; a load sensor detecting a load when the contact part contacts the transport object; and an angle sensor that detects a rotation angle of the contact part relative to the main body, wherein using hardware resources, processings are executed to control the drive part so that load and rotation angle approach a first target value and a second target value based on information of a load and a rotation angle detected by the load sensor and the angle sensor.
