The Challenge of Robotic Precision in Chemical Labs
Robotic manipulation in chemical environments requires extreme precision and reliability. Current systems face significant challenges in autonomously achieving precise measurements and collision-free path planning, especially for delicate tasks like test tube grasping and weighing. Improper trajectory planning can lead to joint instability, reduced motion smoothness, and compromised experimental accuracy, impacting efficiency and safety in automated laboratories.
Integrating Advanced Optimization and Kinematics
This study formulates trajectory planning as a multi-objective optimization problem, balancing motion time, joint jerk, and energy consumption. It proposes an improved OMOPSO algorithm coupled with seventh-order polynomial interpolation to ensure high-order kinematic continuity (C³), critical for smooth, vibration-free motion. Key algorithmic enhancements include a reference vector-guided leader selection and an archive update strategy based on ε-dominance and knee-point evaluation, improving solution diversity and convergence.
Superior Performance Across Benchmarks
Simulation results consistently demonstrate the superior performance of the improved OMOPSO algorithm. Compared to existing methods (CHLMOPSO, MOEA/D-DE, MODE, NSGA-III, OMOPSO), it achieves better convergence accuracy (lower IGD+ values), more uniform solution distribution (lower SP values), and broader Pareto front coverage (higher HV values) across complex benchmark problems like ZDT and DTLZ test suites. This indicates robust and reliable optimization outcomes.
Enabling Next-Gen Automated Chemistry
Experimental verification on a 7-DOF manipulator platform confirms the method's practical feasibility and effectiveness. The optimized trajectories enable stable, smooth, and energy-efficient execution of test tube grasping and weighing tasks without mechanical vibrations or abnormal movements. This significantly enhances the reliability and consistency of automated chemical preparation workflows, paving the way for more advanced and autonomous laboratory systems.
