Title: 6D Singularity Avoidance Proof for Industrial Robotics using $E_6$ Root System Lattices: Validation Description: This dataset provides a comprehensive mathematical and robotic proof for a 6D singularity-free path planning framework. Unlike traditional recovery methods that modify path geometry post-facto, this method utilizes an $E_6$ Lie Algebra root system to generate a 72-node lattice that inherently avoids kinematic singularities. Key Components of this Proof: The $E_6$ Manifold: A 72-node symmetric distribution in 6D joint space, ensuring optimal coverage of the ABB IRB 4600 workspace. Kinematic Validation: The data includes a full Jacobian analysis (Geometric Jacobian) using the standard Denavit-Hartenberg (DH) parameters of the ABB IRB 4600-60/2.05. Numerical Results: - Singularity Avoidance: The Condition Number ($\kappa$) remains stable across the lattice (Median $\kappa \approx 4.5$), representing a significant reduction in singularity risk compared to random joint configurations. Dexterity: The Yoshikawa Manipulability Index ($\mu$) confirms high robotic dexterity at all 72 lattice nodes. Files included: 6D_Lattice_Data_Proof_Corrected.csv: The primary dataset containing Joint Angles, Manipulability, and Condition Numbers. Singularity_Analysis_6D.png: Visualization of the Condition Number stability. Manipulability_Map_6D.png: Visualization of the robot's dexterity across the 6D lattice. E6_Lattice_Projection.png: A 3D projection of the 72-node lattice within the robotic joint space. 6D_Lattice_Robotic_Proof_math.py:The Python source code used to calculate the Jacobian and generate this proof.
