Description

This PR introduces a comprehensive Workspace Analyzer module for robotic workspace analysis in EmbodiChain. The module provides both joint space and Cartesian space analysis capabilities to help understand robot reachability, workspace volume, and performance metrics.

Key Features Added:

  • Modular Configuration System: Type-safe configuration classes for sampling, caching, visualization, constraints, and metrics
  • Multiple Sampling Strategies: UniformSampler, RandomSampler, HaltonSampler, SobolSampler, LatinHypercubeSampler, ImportanceSampler, and GaussianSampler
  • Comprehensive Documentation: Complete user guides and API documentation for all components
  • Factory Pattern Implementation: Unified sampler creation and management system
  • Performance Optimization: Caching mechanisms and efficient sampling algorithms

Components Implemented:

  1. Core Workspace Analyzer (workspace_analyzer.py)

    • Joint space and Cartesian space analysis modes
    • Configurable analysis parameters
    • Integration with simulation manager and robot models
  2. Configuration System (configs/)

    • WorkspaceAnalyzerConfig: Main configuration dataclass
    • SamplingConfig: Sampling strategy configuration
    • CacheConfig: Result caching configuration
    • VisualizationConfig: Visualization settings
    • MetricConfig: Metric computation settings
    • DimensionConstraint: Workspace constraints
  3. Sampling Strategies (samplers/)

    • Multiple statistical and quasi-random sampling methods
    • Factory pattern for sampler creation
    • Performance-optimized implementations
  4. Supporting Modules

    • Caching system for performance optimization
    • Constraint handling for joint limits and collision detection
    • Visualization utilities for analysis results
    • Metric computation for workspace characteristics

Documentation Added:

  • Main Documentation (workspace_analyzer.md): Comprehensive usage guide with examples
  • Configuration Guide (configs.md): Detailed configuration system documentation
  • Sampling Strategies (samplers.md): In-depth sampling method descriptions
  • Visualization Options (visualizers.md): Visualization configuration guide
  • Caching System (caches.md): Performance optimization documentation
  • Constraint Handling (constraints.md): Constraint system documentation
  • Metric Computation (metrics.md): Analysis metrics documentation
