Slipping 4WD Mobile Vehicle Wheels Without Oil or Water

Click For Summary

Discussion Overview

The discussion revolves around methods to make the wheels of a 4WD mobile vehicle slip on a laboratory floor without using oil or water, focusing on maintaining electronic safety and cleanliness. Participants explore various approaches and materials that could reduce friction.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant suggests using snowboard waxing as a potential solution for reducing friction.
  • Another participant seeks clarification on the specifics of the floor and the wheels involved, questioning the context of the problem.
  • A participant proposes fitting outriggers with caster wheels for height adjustment as a means to facilitate slipping.
  • There is a suggestion to consider the coefficient of friction required for the desired outcome.
  • One idea is to make the tires from hard plastic instead of rubber to reduce grip.
  • Another participant recommends wrapping the wheels in tape, noting that different tapes will have varying coefficients of friction.
  • A suggestion is made to use fabric to wrap the wheels, comparing it to the effect of socks on a polished floor, and to consider using powders like drafting powder or corn meal to enhance slippage.
  • A participant mentions that previous attempts with powder resulted in minimal slippage and expresses the need to use rubber wheels.
  • There is a discussion about the potential use of water-based lubricants, with concerns about chemical damage to rubber wheels.
  • One participant questions the necessity of using rubber wheels while trying to eliminate their grip and suggests explaining the underlying goal of the project.

Areas of Agreement / Disagreement

Participants express a variety of ideas and suggestions, but there is no consensus on a single effective method to achieve the desired slipping of the wheels. Multiple competing views and approaches remain unresolved.

Contextual Notes

Participants have not reached a clear understanding of the specific requirements or constraints of the problem, including the type of floor and the desired outcome regarding wheel movement.

Hello Everyone,

I have a 4WD mobile vehicle, I am trying to get the wheel to slip in the floor.

I don't want to use oil or any water product (for my electronic safety and to keep the floor less messy)

Any idea how to make the wheel slip on the floor?

I was thinking about using snowboard waxing but not sure if that is a good idea.

Any idea is welcome here

Welcome to PF.
Is there a language problem here ?
The floor ? The internal floor of the vehicle, the roadway or the ground ?
Which wheel ? The spare wheel, one or all road wheels ?
Is the wheel lying flat or on the tread ? It only takes one or two slim rollers to slide a wheel.
 
For clarification > 1- laboratory floor 2- If the floor is slippery, all wheel should have a hard time gripping (Any wheel)
3- http://www.robotshop.com/en/dfrobot-4wd-arduino-mobile-platform.html (This mobile vehicle look similar)

My question again, how to make the laboratory floor slippery for a mobile vehicle robot?
I am not trying to use oil or soap or any liquid, trying to keep the laboratory floor clean

Any idea ?
 
Fit outriggers with castor wheels and height adjustment .

What coefficient of friction do you require?
 
Make the tyres from hard plastic rather than rubber.
 
Or for a more quick and dirty solution, put tape around the current wheels. Different tapes will have different COF's.
 
Can you wrap the wheels in fabric? Is this floor a waxed or polished floor? You would get the same effect of socks on a polished floor.

The added benefit is that you can scuff up parts of the floor to increase friction.

Is a powder acceptable? Drafting powder is basically finely divided erasers. It makes pretty much any surface slide against any other. Corn meal is used for the same effect on shuffleboards.

I tried powder altering the floor seem to give minimum slippage barely noticeable,

I need to use rubber wheel,

So my option is to change the floor,

I tried the never wet solution but still no luck

any material that has low coefficient of friction with rubber would be great?

If you must use rubber wheels then water based lubricants are really the only choice. Anything else will probably chemically damage the rubber and cause it to swell.

Do you want the wheels to spin under power, or do you want them to slide sideways?
Why can you not simply disconnect the drive shafts to the wheels?
Why must you use rubber wheels and then eliminate the good grip they are designed to provide?

Maybe you should explain what you are trying to do, rather than applying the same arbitrary constraints that are preventing you resolving the problem yourself.
