I'm sure you all have seen tons of R/C beds before...
For the school play Ben and I had to create a remotely driven bed, that rocks in all directions. We are putton A Christmas Carol, and this bed will be used during Scrooge's nightmares. We took the control systems off of one of our old robots, mounted it on the bed along with 6 air compressors, and a ton of air cylinders, 4 pneumatic pistons(1.5in diamater, 8in stroke) and 3 solenoids to actuate the bed. For the drivetrain, we have 2 dualie-style wheels in the center, run off of 2 CIM motors each in a tank style configuration. they power the bed, while the rest of it sits on 4 huge casters. Powering the bed from hell are 2 12v 12Ah gel cell batteries in parallel. We will probably have to add a 3rd or 4th if we plan to move the bed while the compressors are running.
These videos are in chronological order of us getting this bed to run. Expect more videos and pictures soon! sorry for no sound on some of them, I didn't realize I had my laptop muted. Also, nothing happens in the first one til 1:30
