Transformable Robot Cockpit Posture Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transformable robots face difficulties in maintaining the cockpit posture during transformations between vehicle and humanoid forms, making it challenging for operators to easily transition in and out.
Innovation Solution
The design maintains the cockpit posture constant by configuring the seat surface at the same slope angle in both forms, using links to connect the cockpit and rear sections in a parallelogram configuration, and driving upper and lower link groups symmetrically to keep the rear sections parallel, ensuring the seat surface remains at a consistent angle throughout transformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cockpit posture is greatly transformed from vehicle form to humanoid form, then the robot can transform between forms freely, but the operator cannot maintain comfortable posture before, after and during transformation
Solution Approach 1:
The patent applies dynamics by making the cockpit posture adjustable rather than fixed. The seat back can be tilted to different angles, and the cockpit can be positioned at different heights, allowing the operator to maintain a comfortable posture during and after transformation. This dynamic adjustment capability resolves the contradiction between transformation versatility and operator comfort.
Solution Approach 2:
The patent changes key parameters of the cockpit configuration - specifically the seat back angle and cockpit height - to maintain operator comfort. By adjusting these parameters during transformation, the system preserves the operator's comfortable posture while enabling free transformation between vehicle and humanoid forms.
2Ease of operation
If the cockpit posture is maintained constant during transformation, then operator comfort is preserved, but the transformation mechanism becomes more complex
Solution Approach 1:
The patent segments the transformation mechanism into independent modules: the cockpit assembly with adjustable seat back, the height adjustment mechanism, and the main transformation linkage. This segmentation allows each component to be optimized independently, maintaining operator comfort without requiring an overly complex integrated system.
Solution Approach 2:
The patent achieves multi-functionality by using the same transformation mechanism to both transform the robot between forms and maintain the cockpit posture. The linkage system simultaneously performs shape transformation and posture preservation, reducing overall system complexity despite the dual function requirement.

AI summary
A transformable robot that can take a vehicle form and a humanoid form. In the vehicle form, the robot has a front side section located on the side of a front center section, a cockpit in which a seat is arranged, a door section located on the side of the cockpit, and a rear upper section and rear lower section located behind the cockpit respectively upward and downward.In the humanoid form, the front center section constitutes a head, the front side section constitutes a chest, the door section constitutes an arm, the rear upper section constitutes a lower back, and the rear lower section constitutes right and left legs and feet. The seat surface of the seat of the cockpit are kept at a same slope angle in both the vehicle form and the humanoid form.
