In order for you to use the GoTo prom the Position2dProxy, the driver that
provides the position2d must be capable of handling such commands...
Normally, robot drivers (like p2os), do not respond to such commands... You
should try using some higher level driver (if you aren't already) like vfh
What's the cfg file you're using?
