few questions related to inter drone communication about ego-planner-v2 HOT 10 OPEN

1. Agents run ROS master individually and communicate via a bridge we wrote.
2. We use ntpdate for time sync.
3. Of course because the global time is synchronized.

Thanks for the info, I'll understand the bridge communication and update this thread

Hi @bigsuperZZZX
I was wondering, initially when the system starts, all the drones will have a odom "0, 0, 0", how did you find the position of each drone in world frame such that, the offsets are added to the odom of each drone. is it made in a way such that they are equally placed away from each other and this offset is added in the odom from the beginning?

thanks

We do it manually

oh i see, so you transform the odometry of other drones in some central drone's frame right?

from ego-planner-v2.

yes

yes

that's interesting, thanks for the info, I am facing difficulties in fetching orientation for accurate transforms, any ideas for that?

Hi @bigsuperZZZX
why is /others_odom being published from swarm_bridge and traj2odom_node I believe the odom published by traj2odom_node node is generated from received traj based on time allocations and the odom published by swarm_bridge is the true odom published by other agents, I am not sure why both of them are published on same topic and for drone_detect, which odom is useful?
is traj2odom_node only useful for simulation?

to reduce communication burden

I understand, but the o/p of traj2odom_node is useful for drone_detect only right?
