Inverse Kinematics Software Application with Gravity and Friction

Click For Summary

Discussion Overview

The discussion revolves around the search for an Inverse Kinematics Software Application that incorporates considerations of gravity and friction, particularly in the context of a multi-component 2D system. Participants explore various software options and share their experiences related to modeling dynamics and kinematics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant seeks verification of results for variables calculated from constants and experimental data, specifically looking for software that accounts for gravity and friction in a 2D system.
  • Another participant suggests that modeling dynamics in MATLAB or similar software is possible and encourages the original poster to post questions in a single thread for coherence.
  • A third participant assumes the need for a dynamics package due to the mention of friction and gravity, recommending Working Model as a suitable program for linkage design and dynamics simulations.
  • A later reply mentions a personal project involving a speech to sign language translator that requires inverse kinematics, expressing a need for existing solutions in MATLAB and a desire to learn the software quickly due to an approaching deadline.

Areas of Agreement / Disagreement

Participants express varying opinions on the best software options for modeling the described system, indicating that multiple competing views remain regarding the most effective approach to the problem.

Contextual Notes

Some participants highlight the importance of distinguishing between dynamics and kinematics, suggesting that the original poster's needs may require a more complex modeling approach. There is also mention of the original poster's lack of familiarity with MATLAB, which may impact their ability to implement suggested solutions.

Who May Find This Useful

This discussion may be useful for individuals interested in inverse kinematics, dynamics modeling, and software applications in engineering and robotics, particularly those working on projects involving gravity and friction.

I have a multi component system, containing rotation of several linked elements, along with a linked rolling (w/friction) element, a beam element and GRAVITY. What I am trying to do is verify results for varriables calculated manually from constants and experimental data... does anyone know of an Inverse Kinematics Software Application with Gravity and Friction considerations? The system could be considered 2D.
 
Engineering news on Phys.org
Is it possible to model the dynamics in MATLAB or similar software?

P.S. welcome to the forum microRave!

When posting, please post your question to a single thread. It's easier to have a coherent conversation that way. If you put it in the wrong section, the mentors will move it for you.

Since you're talking about friction, gravity, and (presumably) inertia, I'll assume you want a dynamics package rather than just a kinematics one. Working Model is a pretty good linkage design program that allows you to run dynamics simulations, from what I remember. I'm sure there are others that I've either never seen or aren't coming to mind right now... If you really want to get to know your system, I'd go with enigma's suggestion and write your simulation in MATLAB. It's not that hard and you'll have a lot more confidence in your results (no matter how you decide to do it, you should be able to write out the equations of motion).
 
I'm doing a speech to sign language translator and i will need inverse kinematics to keep the avatar in it in shape. at 1st i didn't know its already there in MATLAB and I've been attempting to reinvent the wheel using vb6...my project dead line is in a month. does anyone by anychance have this kinda thing already done. i have no knowledge on MATLAB but I'm trying to learn it now. it would be gr8 if so. i could graduate with some sanity left in me
