Business Context
Robotic systems can support servicing, assembly, inspection, sample handling, construction, and exploration activities that would otherwise require human intervention or dedicated spacecraft. Greater robotic capability, however, can require additional joints, actuators, sensors, mechanisms, and control systems, increasing the number of potential mechanical failure points.
Space TRIZ Resolution
Robotic capability should rely on simplified mechanical architectures combined with sensing, software, and task-specific tools. Common manipulators can use interchangeable end effectors, while passive alignment features and compliant mechanisms reduce the precision demanded from active joints. Complex tasks can be decomposed into simpler repeatable operations.
Applicable TRIZ Principles
Principle 1 – Segmentation divides complex robotic activities into simpler functional operations.
Principle 6 – Universality uses common robotic elements for multiple tasks.
Principle 28 – Mechanics Substitution replaces unnecessary mechanical complexity with sensing and control functions.
Expected Outcome
Greater robotic mission capability
Fewer mechanical failure points
Improved servicing reliability
Reduced robotic-system mass and complexity
Decision Indicators
Early indicators include:
Every new robotic task requires additional dedicated mechanisms.
Mechanical degrees of freedom increase faster than useful capability.
Robotic reliability is dominated by joints and actuators.
Tool specialization creates substantial hardware duplication.
Software or passive mechanical alternatives are underused.
