skruzic's profile - activity

I'm recording odometry and input speeds with rosbag in order to be able to process it later, draw trajectories, etc. Everything is done in simulation using Gazebo and Turtlebot.

The strange thing that happens is that there is about 20% of recorded samples have the same timestamp as other samples, which makes using this data almost impossible. I tried with different simulation step sizes and solvers and eliminated both of them as a reason. I also tried recording on another PC with a better processor and more memory and it did not help either. However, this does not happen when using real Turtlebot.

Can anyone give some advice on what to do?

P.S. I can provide examples if needed.

Hello everyone,

I'm wondering if it's possible to put some text on top of arrow marker in RVIZ. To be more clear, what I'm doing is that I'm collecting laser scan message with distances to obstacles, and showing arrow whose length is proportional to distance to obstacle in the direction of arrow. What I'm trying is to put text with distance in meters on top of that arrow.

I already tried with TEXT_VIEW_FACING marker, but it seems that changing its orientation doesn't help, it always stays same.

Any help is appreciated. Thanks!
