OpenRoberta / openroberta-lab

The programming environment »Open Roberta Lab« by Fraunhofer IAIS enables children and adolescents to program robots. A variety of different programming blocks are provided to program motors and sensors of the robot. Open Roberta Lab uses an approach of graphical programming so that beginners can seamlessly start coding. As a cloud-based application, the platform can be used without prior installation of specific software but runs in any popular browser, independent of operating system and device.

Nao robot not connecting #1532

Closed rbtnx closed 1 year ago

rbtnx commented 1 year ago

For approximately 3 weeks now all of our Nao robots are not connecting to OpenRoberta Lab. I didn't change anything and only had a look at main.py on the robot to see what's going on. The server responds with 404:

[DEBUG] - 2023-07-13 16:56:37.475379 - JSON decoding error (robot was not registered within timeout), reconnecting in 10 seconds...

/usr/lib/python2.7/site-packages/urllib3/connectionpool.py:857: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings
  InsecureRequestWarning)

The request that Nao sends looks like this:

{'files': [], 'cookies': None, 'url': 'https://lab.open-roberta.org/pushcmd', 'hooks': {'response': []}, 'auth': None, 'headers': {'Content-Type': 'application/json'}, 'json': None, 'params': {}, 'data': '{"menuversion": "1.0.5", "token": "TOKEN", "macaddr": "MAC ADDR", "nepoexitvalue": "0", "battery": 99, "firmwarename": "Nao", "cmd": "register", "robot": "nao", "firmwareversion": "2-8", "brickname": "nao"}', 'method': 'POST'}

The main.py script says the endpoint should be /rest/pushcmd so I manually also tried to send the request to https://lab.open-roberta.org/rest/pushcmd, this is the answer:

{"rc":"error","cause":"SERVER_ERROR","server.version":"5.2.2","message":"SERVER_ERROR","_version":"1","initToken":"error","server.time":1689263905130}

This is a bug and we know how to fix it, but unfortunately we do not have a "working" NAO by hand to test it. Have you installed the connector via Choregraphe? If so, I could prepare a fix and you might test it (for us)? If you have installed the connector via the aldebaran store it will be difficult, I think.

rbtnx commented 1 year ago

I did not install the connector, so I don't know how it was installed. I always start the app via Choregraphe and I found the python scripts on the nao itself in

~/.local/share/PackageManager/apps/v6_openroberta_connector/

I can manually patch the files and test it or reinstall the connector via Choregraphe, though.

It seems that this commit removed the deprecated REST API without prefix. Unfortunately this was still used in the naoclient.

bjost2s commented 1 year ago

Please checkout the latest release https://github.com/OpenRoberta/robertalab-naoclient/releases/tag/v1.0.8. It should work now: connecting to the lab and downloading user programs. Please let me know if this fixes your problem.

Thank you very much, worked like a charm!
