Spiro / Staircase

Spiro
Spiro

In this design, each stair that constitutes the assembly of the fold able staircase is in the shape of a sector whose narrow end is attached to a cylindrical ring which is placed onto a main solid rod one on top of the other to make it movable around this rod (axis). Each cylindrical ring has a groove at its top and a pin at its bottom, which draws the above step when the staircase is folded or unfolded. A programmed micro-controller governs the movement of the staircase through an electronic circuit. http://youtu.be/maNYWphrIX8
