Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teleoperational robotic systems face limitations in providing effective remote mentoring due to incomplete sensory information available to mentors, leading to suboptimal guidance for operators.
Innovation Solution
A system comprising a primary and secondary interface with a control system that generates simulated kinematic constraints and provides haptic guidance, allowing mentors to experience similar sensory constraints as operators, enabling precise guidance through the primary input device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If mentors provide remote guidance through a secondary interface system, then mentoring capability is enabled, but the sensory information available to mentors is incomplete, reducing guidance accuracy
Solution Approach 1:
The system creates a copy of the primary interface system's sensory experience at the secondary interface system. The processing unit generates simulated kinematic constraints that replicate the operator's sensory information, allowing the mentor to experience the same constraints and sensory data as the operator, thereby completing the information gap.
Solution Approach 2:
The processing unit acts as an intermediary that receives kinematic constraints from the primary interface system and transforms them into simulated constraints for the secondary interface system. This intermediary process ensures that mentors receive complete sensory information that would otherwise be unavailable at the remote location.
2Measurement precision
If the primary interface system provides full sensory information to the operator, then operational control is precise, but the mentor at the secondary interface system experiences incomplete sensory information
Solution Approach 1:
The system copies the complete sensory information stream from the primary interface system to the secondary interface system through simulated kinematic constraints. This allows the mentor to access the same operational context and sensory data as the operator, eliminating information loss while maintaining operational precision.
Solution Approach 2:
The system extends the sensory information dimensionally from a single-point operator interface to a multi-point system where both operator and mentor can access complete sensory data. The processing unit transmits kinematic constraints across spatial dimensions, enabling remote access to operational context without compromising local control precision.
3Measurement precision
If simulated kinematic constraints are generated for the secondary input device, then mentor guidance accuracy is improved, but system complexity increases
Solution Approach 1:
The processing unit generates simulated kinematic constraints by copying and transforming data from the primary interface system. This copying approach maintains guidance accuracy while using software-based solutions rather than adding complex hardware components, thereby managing system complexity.
Solution Approach 2:
The system replaces potential mechanical complexity with computational processing. The processing unit uses software algorithms to generate simulated kinematic constraints, substituting mechanical constraint transmission with digital signal processing, which reduces physical system complexity while maintaining guidance precision.
