Spiral scissor lift?

  1. Jan 11, 2014 #1
    I am building a robot for the VEX worlds competition and, I was thinking of a spiral scissor lift. But my problem is I only have two mothers to use on this part of the robot. The robot has a square base, so the spiral has to be square. If you could give your theories of how it would work, that would be great.

    Welcome to the forum.
    A scissor lift becomes narrower in one dimension as it gets higher. To do that in a spiral would require a cylinder that reduces diameter as it increases in height. That is not good for stability. What is a mother?
    Is this anything like your concept; http://en.wikipedia.org/wiki/Hyperboloid_structure
    It would be good if you could link to a picture similar to what you have in mind.

    This is the robots base if this helps.
