SCHED_DEADLINE is a free real-time Linux scheduler.
This demo shows a Linux PC driving, at the same time:
- 2 ball-and-beams with different time granularities
- one robotic arm with inverted pendulum
- a graphical monitoring application

The robotic arm moves along an ellipse keeping the pendulum in position. Ball-and-beams, instead, have been given less bandwidth, because most of the CPU bandwidth was needed by the inversed pendulum.

The ball and beams and the robotic arm where running all at the same time. Unfortunately, however, the movie has been filmed in sequence, and then assembled to let people understand that all these activities were concurrent (we were not able of making three video simultaneously). The robotic arm has been started after the ball-and-beams, and this is the reason why you can see the arm stopped in the background of the ball-and-beams. The full movie (i.e., filmed in sequence) is available at http://www.youtube.com/watch?v=UJSWvC...

The demo has been realized for the ACTORS project (http://www.actors-project.eu) financed by the European commission.
