Agent falls over without effector messages #30

Open osrf-migration opened 8 years ago

Original report (archived issue) by Jens Fischer (Bitbucket: Gama11).

Originally mentioned in #24.

When the playmode is set to PlayOn, the agent will fall over if there are no effector messages sent.

The expected behavior is for the agent to remain in a stable, standing position like he does in SimSpark:

Just out of curiosity, why an agent doesn't want to send effector messages after spawning a model in simulation? Or is this a timing issue? Maybe it takes some time to apply the first effector message and the robot is already unstable.

magmaOffenburg's agent currently has some trouble with effectors. This seemed like a good way to debug it - start from a stable position, without sending any messages, and then start sending effector messages step by step to see where it goes wrong. Of course, this approach didn't really work because the initial position is not stable to begin with. :)
