The video you are about to see is a scale model of a BackHoe excavator. It has simulated hydraulics, and was built by Michael Adler to demonstrate how this can be done in Meccano, and to experience controlling such a machine. The six motors are driven using a Pulse Width Modulation Controller with joysticks, just as in the prototype (Armchair Control).
This is believed to be the first time a working Meccano model has been demonstrated over the Internet.
The file was captured using a standard video camera. It was then linked to the computer via a video card and the appropriate software. This video runs for only 14 secs, but gives enough time to see the construction, as well as some of the main movements. If you can download at say 2.5k/sec, then the file will take 3.3 minutes to download. After you receive the file, the unzipped file is called capture.avi Windows 95/98 programs should be able to run this automatically by double clicking on the filename.
