Linear deploying objects at equal distances 1b

The green nut is fixed to the first pink slider.
Turn the orange screw to move the pink sliders, thus to control their linear positions.
The distances between the pink sliders are kept always equal to each other thanks to the blue bars that connect the pink sliders. The slider position accuracy is affected by the gaps in the blue bar revolution joints.
This video aims to overcome the disadvantages of the mechanism in the video
• Linear deploying objec...
in which the pink slider cannot move properly because the force acting on the slider is not symmetrical.
