We noticed that in some cases, the turtlebot struggles to setup its network connections and stays unreachable.
The script below acts as a workaround:
#!/bin/sh
# Turtlebot startup script
# By Grégoire et Amaury
# Executed at robot startup to speed up deployment when experimenting
# Starting the ssh server service
service sshd start
# Trying to ping the router
ping 10.0.0.1 -w 5 -c 5
# Trying to ping the desktop PC salade
ping 10.0.0.2 -w 5 -c 5
# To check if the script runned well
