Nettet21. nov. 2024 · Too coarse collision checking: Sampling-based planning needs to validate whether a collision-free path exists between a newly sampled configuration and an existing one. This checking is performed in MoveIt in a discrete fashion. If this discretization is too coarse (larger than the smallest object dimension), the check …

Adding continuous self-collision checks. Currently with Bullet, CCD is only possible for robot-world collision checks. However, continuous self-collision checks are useful too and can be built upon the already … nettle tea plant feed

"NettetNo continuous collision checking is currently available in OMPL/MoveIt, though this is an area of current discussion. Specifically, longest_valid_segment_fraction is the fraction of the robot’s state space that, given the robot isn’t currently in collision, we assume the robot can travel while remaining collision free.

Nettet7. aug. 2024 · On move_base interface I can order the arm to move to a named target defined as group_state on the SRDF. But to do so, MoveIt! always perform self-collision checking, what is fine, except when I want to start the arm in the "home" position, that in my case is comfortably folded, so it keeps that pose when powered off (will post a … NettetTime Parameterization¶.
