Realize this would be very involved compared to building a frame and shimming/wedging things underneath to create break. It's feasible to use small linear actuators (small electronic device that slides a bar in/out - typically used for car stereo installs/lowriders to move panels/amps/etc). They're typically strong enough to support your weight should you walk on them, relatively simple to wire/control, and would probably do the trick. You'd just need to build the top of the platform out of smaller square sections, and not screw them down. Sort of like a tongue and groove floor, you're just looking for a "floating" platform. When triggered, the actuator would lift one of the 4way corners, creating break. It'd be a bit of a pita to get them level, should you want a straight uphill putt, but from the sounds of things, you're looking for a lot of "randoms". You'd need to use some form of padding underneath to smooth the edges, and fabricate brackets to lock the plywood sections to the actuator, so they can't slip. A lot of potential pitfalls, but hey, I tried. ;) You could potentially mimic their methods, as well. The cheap scissor jacks for spare tires would do the trick, and absolutely support the weight. You'd just need to attach a bar extension to the eye ring, so you could adjust them from the side of the platform. In either case, you'd need to have excess fabric at the sides to prevent stretching. *shrugs*
In short, there's a reason the adjustable greens cost so much. ;) I'm curious as to how close I am to the patented methods though. :D
