Hi, I have since tried the Pyrobot knopix distro, and I still have
issues with the blob handling.
In the pyrobot Interface app, when I try to interact with the robot
and simulator to try and retrieve blob info ( this is with stage,
using a world file with blobs, and a cfg file with blobfinder)
When i issue commands like robot.blobfinder[0] to access data I get
nothing, is there any good reference for me to try and understand the
pyrobot blob routines any better, It seems like the docs on the web is
a bit dated?
Has anyone gotten the player/stage blobfinder stuff to work in pyrobot?
