SUMMARY

The discussion centers on designing a square spiral scissor lift for a robot intended for the VEX Worlds competition. The challenge arises from the need to create a stable structure using only two motors. Participants highlight that a traditional scissor lift narrows as it ascends, complicating the design of a spiral lift that maintains stability. Clarifications are made regarding terminology, specifically the confusion between "motor" and "mother."

PREREQUISITES
  • Understanding of VEX robotics components and configurations
  • Knowledge of scissor lift mechanics and stability principles
  • Familiarity with spiral structures in engineering
  • Basic robotics programming for motor control
NEXT STEPS
  • Research VEX robotics motor configurations and limitations
  • Explore design principles for stable scissor lifts
  • Investigate spiral lift mechanisms and their applications
  • Learn about hyperboloid structures and their stability advantages
USEFUL FOR

Robotics enthusiasts, VEX competition participants, engineers designing lifting mechanisms, and anyone interested in advanced robotics structures.

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.
 
i meant motor not mother.
