Robotic Assistant Foldable Seat Control for Walking Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robotic assistants primarily focus on virtual or psychological interaction, lacking effective physical interaction and human-robot interaction, which limits their ability to provide substantial walking assistance and body training effectively.
Innovation Solution
A robotic assistant with a base, elevation mechanism, sensors, and a control system that includes a touch-sensitive display and camera, allowing for adaptive height adjustment, obstacle detection, and user interaction, enabling physical support and training through movement and bio-character monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If robotic assistants are designed with humanoid form focusing on virtual or psychological interaction, then user interaction capability is improved, but physical interaction capability deteriorates
Solution Approach 1:
The robotic assistant is designed to perform multiple functions including physical support through the support mechanism, mobility assistance through the base mechanism, and interactive communication through the display device. This multi-functionality allows the robot to serve both physical assistance needs and social interaction needs, resolving the contradiction between virtual interaction capability and physical interaction capability
2Ease of operation
If robotic assistants provide physical support for walking, then user fatigue is reduced, but device complexity increases
Solution Approach 1:
The robotic assistant is divided into distinct functional modules: a base mechanism for mobility, a support mechanism with adjustable height for physical support, and a display device for interaction. This segmentation allows each component to be optimized independently while working together to provide walking assistance, reducing overall system complexity
Solution Approach 2:
The support mechanism features adjustable height capability, allowing the robotic assistant to adapt to different user needs and walking conditions. This dynamic adjustment feature enables the system to provide optimal physical support without requiring a completely complex redesign for different scenarios

AI summary
A robotic assistant includes a wheeled base, a body positioned on the base, a foldable seat rotatably connected to the body, an actuator to rotate the foldable seat with respect to the body, and a control system that receives command instructions. The actuator is electrically coupled to the control system. In response to the command instructions, the control system is to control the actuator to rotate the foldable seat to a folded position or an unfolded position. The control system is further to detect whether an external force from a user has applied to the foldable seat, and release the actuator to allow the foldable seat to be manually rotated.
