With these motion simulators they’re generally solving the same problem with two solutions.

The problem is moving the platform, ie you, in at least 2 degrees of motion quickly and a fairly large distance. However, every single solution relies on  basic premise that hasn’t changed since flight simulators were invented : they lift the platform. This means the motors must be expensive and use a lot of power since if someone weighs 100kg, even a 3dof platform needs to lift 33kg each and if you require a large amount of motion the power requirements are huge.

That is why this platform cost $10k, the motors were $5000 for six and the control unit was $2500.

Some prefer to balance the platform on a spring which reduced the power needed but we still have a small range of motion and this can be quite jerky.
