Troubleshooting
Q: Unable to connect to xiaoqiang after app launched
A: It may be because Xiaoqiang and your phone are not in the same LAN. It is also possible that Xiaoqiang's server-side program does not start. You can enter sudo service startup restart
to restart the service program and try again.
Q: Unable to remote control after successful connection
A: Check whether the driver is operating normally. Check whether the serial port USB of xiaoqiang is properly connected. Then enter rostopic echo /system_monitor/report
. If the voltage is normal, then the platform is normal. If the voltage does not display properly, restart the service and see sudo service startup restart
. If the voltage is normal but still can't move, check if infrared sensors triggered. The infrared sensor will glow red when triggered.
Q: No video transmission after successful connection
A: Check if the camera USB is connected properly. Then restart the service and try again sudo service startup restart
