Multi-Objective Trajectory Planning with Dual-Encoder
CoRR(2024)
Abstract
Time-jerk optimal trajectory planning is crucial in advancing robotic arms'
performance in dynamic tasks. Traditional methods rely on solving complex
nonlinear programming problems, bringing significant delays in generating
optimized trajectories. In this paper, we propose a two-stage approach to
accelerate time-jerk optimal trajectory planning. Firstly, we introduce a
dual-encoder based transformer model to establish a good preliminary
trajectory. This trajectory is subsequently refined through sequential
quadratic programming to improve its optimality and robustness. Our approach
outperforms the state-of-the-art by up to 79.72% in reducing trajectory
planning time. Compared with existing methods, our method shrinks the
optimality gap with the objective function value decreasing by up to 29.9%.
