About this paper
Martin Rudorfer
Researchers at Aston University developed RM4D, a novel combined reachability and inverse reachability map that reduces the dimensionality of robot workspace representation from 6D to 4D for common 6- and 7-axis robot arms. This approach achieves an order of magnitude reduction in memory requirements and construction time compared to existing methods, while maintaining high accuracy and demonstrating robustness to kinematic assumption violations.
Key insights
- The inherent kinematic structure of common 6- and 7-axis robot arms allows for a substantial and effective dimensionality reduction of their workspace.
- A unified 4D map, storing canonical end-effector and base parameters, can efficiently serve both reachability (forward) and inverse reachability queries, simplifying planning workflows.
- The derived 4D representation demonstrates robustness to moderate deviations from its underlying kinematic assumptions, broadening its practical applicability to various robot models.
