Is GitHub - UniversalRobots/RTDE_Python_Client_Library: RTDE client library and examples still supported? Looks like it was checked in but then no activity since then.
I just posted this:
Copying here for convenience and visibility:
Seems like RTDE expects you to poll it continuously after you connect if you want fresh data. It’d be good if that was clearly called out in the docs.
If I do this:
rtde.connect() time.sleep(11) rtde.receive()
I get errors like
received 0 bytes from Controller, probable cause: Controller has stopped or
received 0 bytes from Controller. Also, I’ll often get two stale messages before it notices the disconnect.
Receive has to be called frequently, otherwise input buffers overflow.
UR should be more explicit about that in the API documentation. Thanks for reporting.
