Demountable Paved Platform

 · Surface area: about 80 m2 (Modular construction. Each module size: 1.2m2)
    Shape can be varied from 9m x 9m to 2m x 34m (can be L shape, U shape etc...)

 · Interchangeable surfaces : concrete, asphalt etc.
    The platform has been designed to feel like solid ground by using robust structual elements to resist
    horizontal linear and rotational loads as well as vertical forces.

 · Vertical range: Maximum 500mm with an accuracy of 0.5mm
    The platform includes 176 computer controlled actuators, 52 reactive lateral stabiliser columns and 84 manually adjustable legs.

We can change its shape and surface profiles by means of its modular construction and the computer controlled arrangement enabling us to make slopes, gaps etc. which are repeatable thus enabling us to study the effects of changes in the surface (including surface type); we can place obstacles on it according to desired layouts. The platform can also be made wet if desired. Currently we have a surface akin to a pedestrian footway (concrete pavers) but this can be changed if desired. We can incorporate slopes of up to 20% (over a short distance) in different directions and step heights of up to 500mm. With PAMELINA, a small wooden platform, we can also test effects of horizontal gaps mixed with vertical gaps
