Rigging robot toes

Support Animation and Rigging

Hello,

So I have this robot leg that I am almost finished rigging.

I have IK and some other stuff already in place but I’m facing a problem I don’t know how to solve :
I’d like the three toes to follow the main foot with some delay. Eg. when the foot goes up they point downward a little and when the foot goes up they point upward a little.

Here’s a mockup pose of what I’m trying to achieve.

I could animate it by hand later but if there’s a quicker solution involving bone constraints or drivers I’d be interested in one.
Any ideas or suggestions?

Delay drivers are a bit tricky to set up - drivers define a f(x) relationship where y = …x… same thing with bone constraints. You have to save all the x data and work with that data array:

Thanks, this looks quite complicated though, I was looking more for doing this with a bone constraint if possible.

There’s not a simple way to do this

I should clarify- doing this without the delay is extremely simple. Doing it with the delay requires scripting

The tricky way it is then ! I’ll give it a try.

Ok so how would you go about doing it without the delay?

If you’d require full control this set up may work for you, as there will probably be instances where you don’t want the toes to drag:

Ah that’s clever ! I’ll try this tomorrow !

I did a variation on your solution and it fits my needs. Thank you!
