Pretty darn good...
This flash had some awesome graphics and really well designed backgrounds, and I really like the song you used. This flash would be a good precursor to a longer flash movie, one with a story behind it.
Maybe the robot is pronounced defective, but fights its way off the production line dodging lazers and saws and all that. You should give it some semblance of a human face to allow viewers to empathise with its flight to freedom, maybe just grey lines outlining eye sockets and a mouth.
Make sure you don't do too many camera zooms in and out, it distracts from the running motion of the robot if the view is jumping all over the place. There should be a front on view of the running robot's face with the facility looming behind him as he runs.
Overall, a really good start and I hope you make many more like this!
Keep going, don't quit!
