Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assistive robot systems are not autonomous and pose difficulties for users, particularly elderly or individuals with reduced mobility, in lifting objects off the ground or floor surface.
Innovation Solution
A lifting robot system comprising a sensor device and a robot device with a lifting component and collection tray, which automatically detects objects, places them on the collection tray, and lifts the tray from a first height to a second height upon receiving a command.

Engineering Contradiction Analysis
1Extent of automation
If a manually operated arm with gripper is used, then the device structure is simple, but the system is not autonomous and still presents difficulties for users with reduced mobility
Solution Approach 1:
The robot device is divided into distinct functional modules: a mobile platform with sensors for autonomous navigation and object detection, a mechanical arm with gripper for manipulation, and a lifting component for elevation. This segmentation allows each module to be optimized independently while working together to achieve full automation.
Solution Approach 2:
The patent combines multiple functions into an integrated robot device: the mobile platform integrates navigation and detection, the mechanical arm integrates positioning and grasping, and the lifting component integrates support and elevation. This merging creates a cohesive autonomous system that eliminates the need for manual operation.
2Ease of operation
If the robot device includes multiple components (sensor device, lifting component, collection tray), then the automation capability is enhanced, but the device complexity increases
Solution Approach 1:
The robot device is designed as a multi-functional system where the mobile platform serves both navigation and object detection purposes, the mechanical arm performs both positioning and grasping operations, and the lifting component provides both support and elevation functions. This multi-functionality reduces the need for separate specialized components.
Solution Approach 2:
The collection tray is integrated with the lifting component, which is in turn integrated with the mechanical arm structure. This nested arrangement allows components to share structural elements and mounting points, reducing overall system complexity while maintaining full functionality.
3Adaptability or versatility
If the lifting component raises the collection tray to a second height, then accessibility for users with mobility issues is improved, but the device complexity increases
Solution Approach 1:
The lifting component is designed with adjustable height capability, allowing the collection tray to be dynamically positioned at different elevations. This dynamic adjustment enables the system to adapt to users with varying mobility needs and different task requirements, enhancing accessibility while using a relatively simple actuated mechanism.

AI summary
Lifting robot systems and methods for operating the same are disclosed. A lifting robot system includes a sensor device and a robot device. The robot device includes a body, a lifting component movably coupled to the body, and a collection tray coupled to the lifting component. Upon receiving a command to lift an object, the sensor device automatically detects the object, the robot device places the object on the collection tray, and the robot device causes the lifting component to lift the collection tray from a first height to a second height.
