Quastion about parallel robot with rolling pairs

Click For Summary

Discussion Overview

The discussion revolves around the concept of parallel robots utilizing rolling pairs, specifically focusing on the application of such structures where spherical surfaces roll against each other. Participants explore the mechanics and potential uses of this robotic configuration.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Hossein inquires about the applications of parallel robots with rolling pairs, specifically involving spheres rolling on fixed spheres.
  • One participant interprets the question as relating to a ball used for robotic movement, comparing it to a mouse ball and discussing the mechanics of drive motors and balance circuitry.
  • Hossein clarifies that he is referring to parallel robots with higher pairs, emphasizing the contact surfaces as spheres rolling on each other.
  • Another participant expresses uncertainty about the topic, indicating it is beyond their expertise.
  • A participant questions whether the discussion pertains to a ball and socket joint.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the specifics of the topic, with multiple interpretations and uncertainties present in the discussion.

Contextual Notes

There are limitations in the clarity of terms used, such as "higher pairs" and "rolling pairs," which may depend on specific definitions within robotics. Additionally, the application context remains vague and unresolved.

Who May Find This Useful

hi
are every one know about parallel robot with rolling pairs for example one sphere rolling pn the fixed sphere.
my quastion is the application of this structure.
tnx

Hi, Hossein.
I anticipate some language difficulties here. Are you referring to a ball used instead of wheels for robotic movement? If so, such is set up much like a mouse ball for a computer. The drive motors run rollers or wheels which impart motion to the ball through friction. In cases with intense dedicated balance circuitry, one ball is enough. It is more practical in most cases, however, to have a stable structure with 3 or more balls, or with a drive ball and stabilizer wheels.
 
hi
thanks for your answer.
no i search about parallel robot with higher pairs infact. the contac surfaces are sphere and rolling on each other
 
Hmmm... I'm afraid that you'll have to wait for someone else to respond. This is out of my league.
 
do u mean ball and socket joint?
