SUMMARY

The forum discussion centers on designing a pole-climbing robot capable of ascending a 5-meter scaffolding pole while carrying a load of five standard engineering bricks. Key design considerations include the use of high-friction wheels to ensure grip on the pole and the need for calculations related to friction force, specifically using the formula F = μ * N, where μ represents the coefficient of friction. Participants suggest researching rope climbing techniques for additional insights and emphasize the importance of calculating the friction force to ensure the robot can support the weight during vertical ascent.

PREREQUISITES
  • Understanding of mechanical design principles
  • Friction calculations using F = μ * N
  • Basic robotics concepts, including motor selection
  • Familiarity with materials, specifically rubber and galvanized steel
NEXT STEPS
  • Research high-friction materials suitable for wheel design
  • Learn about motor selection for vertical climbing robots
  • Investigate rope climbing techniques for mechanical inspiration
  • Calculate the coefficient of friction for rubber against galvanized steel
USEFUL FOR

This discussion is beneficial for mechanical engineering students, robotics enthusiasts, and anyone involved in designing climbing mechanisms or automated systems for vertical transport.

Pole Climbing Robot, Please Help!?

Hi, I have been given a project for Mechanical Engineering 1st year. We have been given no ideas and I cannot go to the lecturers for any help and I do not have any previous knowledge even on the basics.

Guidlines are as follows:"Design an robot capable of climbing a standard scaffolding pole to a height of 5m while carrying a
load of 5 standard size engineering bricks. It must automatically stop at a height of 5m, then wait 30
seconds during which the bricks are manually removed before automatically reversing and finally
stopping at the bottom"



Homework Equations





The Attempt at a Solution


My initial ideas are four very high friction wheels incorporated into a sort of 'ring' that clamps around the scaffolding pole and some sort of tray with a hole to accommodate for the pole which attaches on top of this ring to carry the bricks. I haven't even thought about motors or any electronics as of yet, but how does this idea sound to you guys? Is it possible for the wheels to provide enough friction to withstand the weight of 5 bricks?

Something along the lines you have suggested sounds pretty good to me.Here's something else to think about...google rope climbing techniques and perhaps that may give you some ideas.It sounds like an interesting project.Have fun.
 


Im doing exactly the same thing for my project.
Im lost as to what calculations I need though.
My robot will be climbing a galvanized lamp post and am planning on using either wheels or tracks.
Do I need to calculate friction force seeing as it will be climbing vertically?

Yes, you basically need to use F = mu * N.
 


Thanks Berkeman. Ill see what figures I can come up with.
I will need to find mu for rubber and galvanised steel to get F.
