This is | How can we move something in every three dimensional direction? <br><br> | ||
A mechanical feature of thread is that it can pull - but it can't push. <br> | |||
This structure helps to move things with thread by the use of additional mechanical support.<br> | |||
It is meant to be used by two peoples who operate two strings (yellow, each person) in order to move the object.<br><br> | |||
One important part of that structure is a spring (green). <br> | |||
It is attached to a fixed spot in the room. It stretches and contracts itself when the attached object is moved 1) parallel to the ground and 2) up and down. <br><br> | |||
Another essential aspect is the thread that goes through / is attached to the middle of the object. <br> | |||
It holds the object in place so that a precise movement is assured.<br> | |||
It also takes away some of the objects weight in order to exonerate the operator strings.<br><br> | |||
A third important part are the structures that attach the "middle-thread" (red) to the ceiling and the ground.<br> | |||
They 1) hold the middle-thread in place, they 2) react to the operators movements by turning in the required direction (blue wheel) and they 3) provide a bracket for the spring.<br> | |||

== Pulleys == | |||
<br> | |||
This is an assembly kit that allows to work with pulley/thread constructions in a flexible way. <br> | |||
It works best with flat and smooth surfaces and it can be used in vertical and horizontal constructions<br> (such as logical operations, see Rachel Smith's and + or gates).<br> | |||
The parts:<br> | |||
1) 3D printed pulley wheels <br> | |||
2) metal ball bearings <br> | |||
3) plastic suction pads and <br> | |||
4) thread. | |||
