[Solved] Timed out waiting for transform from base_link to map during map navigation

[wdxpz]

Hi, Adam,

Thanks very much for your help!

for the error I mentioned in

@wdxpz

Recently, I installed Ubuntu 16.04 + ROS Kinetic for Upboard on my rosbot 2.0 pro and connected it with roscore running on another ubuntu 16.04 machine (with ros-kinetic-desktop-full and dependencies installed).

Currently, I can control my robot to do map slam and map navigation. But there is a Extrapolation Error always poping up during the map location.

I tried to solved it by rospy.Time.now() to rospy.Time(0), but I wondering if it is right?

BTW, I am now trying to do the multirobot navigation by namespace, but encountered some errors, I post another article Multirobots navigation with namespace failed to seek help. Would you please have a check and give me some guidance!

Thanks very much!
