Re: ROS publishing tf info

Thank you so much fferi for you response. indeed, in RVIZ it looks normal! see pictures. Thats why I didn't realized it in first place But I have to send the inverse back to V-REP too, to move into the right direction. Could it be that I have to publish a /map coordinates?

Furthermore C has the best performance. If it's a specific question to V-REP, you have to wait for the supp...
