Update GoToPlace to allow finding nearest spot
#308
Conversation
This commit adds support for selecting the nearest spot on the same floor. This behaviour is convenient when looking at things from a cancellation perspective. This commit depends on open-rmf/rmf_task#101 Signed-off-by: Arjo Chakravarty <[email protected]>

I have not implemented flexible constraints here. If we really need it can do it in a follow up pr. Signed-off-by: Arjo Chakravarty <[email protected]>
This pr depends on: * open-rmf/rmf_task#101 * open-rmf/rmf_ros2#308 You can ask a robot to go to its nearest spot using the newly added script. Signed-off-by: Arjo Chakravarty <[email protected]>

Thanks for working on this! Tried it out with the demos script and it's working for me 👍 I see that having the final selected destination to be on the same map is a requirement in the code itself because of the lack of API for constraints. Right now it seems like if all the locations provided are on a different map from the robot, the first place provided will be the destination. Should we not make this behaviour a default and allow the robot to take lifts? Or is this only temporary until the constraints API are added in? |

Constraint property should be category instead of type according to the schema

I can't believe I messed up my own schema.

This commit adds a stupidly simple parking spot system. It ensures the next location a robot goes to is not occupied. It also publishes currently free parking spots. When combined with #308 it allows a robot to move to the nearest free spot instead of the nearest spot only. note: This PR still needs more testing Depends on: - open-rmf/rmf_internal_msgs#63 Known issues: - When the robots start in simulation not all robots seem to be running the idle task, hence some robot dont end up claiming parking spots.

New feature implementation
Implemented feature
This commit adds support for selecting the nearest spot on the same
floor. This behaviour is convenient when looking at things from a cancellation perspective, one may want to go to the nearest parking spot for instance.
This commit depends on open-rmf/rmf_task#101
Note: While the schema supports contraints, we don't yet have an API to express such constraints, hence by default it will always use the same floor constraint.
