About this paper
Jeremy Morgan, David Millard, Gaurav S. Sukhatme
CppFlow, developed at USC, presents a hybrid planner for Cartesian Path Planning that integrates generative Inverse Kinematics with global search and Levenberg-Marquardt optimization. It achieves a 100% success rate on challenging benchmarks and finds valid solutions up to 129 times faster than state-of-the-art methods, while maintaining comparable trajectory quality.
Key insights
- Integrating efficient, approximate solutions from generative AI with the precision and guarantees of traditional planning and optimization leads to enhanced performance.
- Learned generative Inverse Kinematics models can effectively explore the high-dimensional null space of redundant robots, producing diverse and smooth candidate trajectories.
- Employing a non-stationary objective function in the optimizer helps maintain valid pose trajectories while optimizing for smoothness and collision avoidance.
