EXCELLENT DEMOSTRATION OF JOINT CONSTRAINS

A bit late to the party, but I'll give it a shot: What are the animation differences? For an exercise, I modeled a robotic arm. It has three segments and a claw, and what I wanted to be a swiveling base. I have failed miserably. The assembly model itself I'm good with. But, to get it animated, I brought everything together using constraints. Then, I tried to animate the constraints. Things start flipping all over the place and twisting in weird directions, and some relationships go in the wrong direction (e.g., the base moves when I'm trying to move a part of the arm). I went through this 2 or 3 times, then decided to try joints. I used several rotational joints, but also employed some mating constraints. I cannot make both animate in the same scene. And, I can make neither animate properly, as things begin to flip around or bend in ways I never intended. I've modeled other things, and their animations did not have these issues. So... Is there any way to combine animated joints and animated constraints? If not, what would cause all the flipping and reverse-direction relationships? Thank you.

You didnt really use Constrain at all. How does this video show the difference between the two? Its a really good video on joints but no mention of constrain

Loved the music.

There is a typo in the first cloud.

Why not add voice explaining whats going on?

do you have the part files to share?

the music is like Cooking

super

Do you have part drawing

Chris Bond, would you be willing to share the parts? I'd love to practice this

This song kicks ass. What is it?

lose the tunes

Absolutely useless
