Hi,
Downloaded melody ros image for ROSbot2.0 and ubuntue 18.04, tinkerboard from the husarion website at step 2, and flashed to the sd card using etcher at according to step 4 at ROSbot 2.0 & ROSbot 2.0 PRO | Husarion.
Followed steps at ROSbot 2.0 & ROSbot 2.0 PRO | Husarion
- Connect to a Wi-Fi network using Ubuntu GUI…
The only option available is to connect hidden WiFi. After entering ssid and password. It would not connect
After 1/2 hour, i rebooted and it connected to WIFI.
To find ip address, I had to use
$ dig +short myip.opendns.com @resolver1.opendns.com, and then
$ ifconfig to ip address.
Next, i was able to ssh. (NOTE: I did have to activate ssh on my laptop due to installing ubuntu 18.04, and ros melody).
Then, it froze. I again connected the keyboard, and mouse. It ask me repeatedly to connect to WIFI. it does not connect to WIFI.
any suggestions?
Thanks
Vineet
Adam,
Answer to your questions
-
It is rosbot 2.0
-
reimaged again with balena three times.

This time, it listed WIFI available and connected to it. Battery low.
I will charge and see how it behaves tomorrow.
Thanks

Adam,
I am unable to connect again.
I connected the monitor, keyboard, and mouse.
I turn the switch, and it is not starting up.
Suggestions?
Hi Vineet,
Your problem can be connected with Wi-Fi antenna damage which you describe me in previous mails. May I ask you to try change antenna for different one or plug in some USB Wi-Fi module into back panel and check if connection still be very unstable?
Best regards,
Hubert
Hubert,
I have ordered antenna, and i will test shortly, and let you know the results.
Thanks
VIneet
Hubert, Adam,
Replaced antenna, and it connected right away.
as i am doing next steps, it keeps disconnecting.
Thanks
Vineet
Hubert, Adam,
After replacing the antenna, It is connecting to the wifi every time for the past 6 days.
I think after accidentally flipping the back end of the rosbot, i damaged the antenna.
Thanks again
Vineet
