Nav2 robot jerks frequently on random occasions
Hi,
I have tried DWB and RPP controllers but my robot vibrates & jerks very intensely. plotting the cmd_vel shows the linear x jumping between +0.5 and -0.xx. My CPU load on a Jetson Xavier AGX is quite low during navigation.
Any suggestions to fix this issue? I am wondering if velocity_smoother is able to fix this issue but there are no humble binaries for velocity_smoother and i'd prefer not to build the whole nav2 from source.
