HI, I am having a couple strange issue on this chapter:
1 - unlike the other chapters, the rviz showsup on GUI automatically without me starting one on any terminal, and if I close the rviz it would also force the sim and terminals to reconnect.
2 - the laser & pose array often show weird jiggering with the following errors:
Transform [sender=unknown_publisher]
For frame [map]: No transform to fixed frame [summit_xl_a_odom]. TF error: [Lookup would require extrapolation into the future. Requested time 153.751000000 but the latest data is at time 153.072000000, when looking up transform from frame [map] to frame [summit_xl_a_odom]
Any idea if I had messed up some setting or its a bug in the coursework setup? would appreciate some help so that i can carry on the coursework~
