Drawing Machine Kinematic System

Hi all,

I’m looking at making a more complex version of my initial drawing machine test, originally posted here (for reference):

Kangaroo Kinematic System

Here is the simple version of what I am trying to achieve that is working fine. Note the “bending” input maintains an aligned straight line anchored at the midpoint “t”

Here’s the file:

The problem I am stuck on is in the more complex version of this script with 3 cogs and 8 line segments. The bending component is not working how I would like it to, yet. Here is an annotated diagram of what am trying to achieve. Note the two line segments that I would like to “align”. I can’t seem to figure out why the bending component is not working in this simulation
Here’s the script:

Any advice or suggestions would be most welcome. Is it not working like the simple version because the line input is a closed polyline? Or, have I not correctly ordered my data trees?

Many thanks in advance,


@DanielPiker, do you have any thoughts on this?

start the timer in the green group.

it’s not the same as you are planing but maybe a starting point

Hi, @Konrad, Thanks!

This indeed gives me some alternative ideas to try. Appreciate your sharing this.

I’ll give this some further effort and hopefully be able to post an update again soon.
