Discussion Overview

The discussion revolves around the design and mathematical modeling of a DSLR boom crane that operates using stepper motors on a turntable. Participants explore the mechanics of the system, focusing on the forces involved and the movement axes, while seeking guidance on how to approach the mathematical modeling without considering construction materials at this stage.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant describes the setup involving a boom crane mounted on a turntable, highlighting the adjustable load distance and the known weight at one end.
  • The participant expresses a desire to focus on the forces involved and the mathematical modeling of the system, specifically regarding the two axes of movement: vertical and rotational.
  • Another participant indicates their inability to assist due to the complexity of the problem and suggests that a textbook might be helpful.
  • A further reply questions the selection of an appropriate textbook given the vast number available, indicating confusion about where to start.
  • One participant encourages a proactive approach to learning, suggesting that engaging with the material independently is beneficial.

Areas of Agreement / Disagreement

The discussion does not reach a consensus, as participants express varying levels of ability to contribute and differing opinions on the usefulness of textbooks versus independent exploration.

Contextual Notes

Participants have not settled on specific mathematical approaches or models, and there are unresolved questions about the appropriate resources for learning.

Hi forumers!

I have a concept for a DSLR boom crane and I want to operate it using stepper motors via belts/gears or pulleys.

It will be mounted on a driven turntable bearing on a tripod.
The boom acts like a see-saw when mounted on the turntable.
The load distance from the apex of the tripod will be user adjustable (0.5m, 1m, 1.5m)
I have a known 5Kg load at one end.

I guess I have two axis of movement at the moment. Vertical (boom up/down) and rotation about the center of the tripod (turntable).

Where do I begin with the math for modelling this? I want to disregard construction materials just now and focus on forces involved.

Thanks
Andy

Bump!

Anyone? Thanks.
 
I have read this but I'm not able to help, I'm afraid. Too hard for me to deal with.
Maybe these two posts will find someone's email and they'll be able to help.

btw, Have you tried a textbook?
 
A textbook would be fantastic, but which is appropriate? There are a few thousand of them and I'm lost as where to start.

Thanks
 
Just get stuck in - like we all had to before the Internet and these friendly forums were invented! :smile::smile::smile:
