Here are some animations of the robotic arm named simply "Ivan" that I am
creating for e-NABLE.

Robot arms are very interesting to me and I'd like to build one someday.  I'd
love to learn more about this project.

Unfortunately your animations are not working on this forum, it looks like
you uploaded just thumbnails or a single frame somehow.  I know the forum
also has fairly low attachment filesize limits, which could be part of the
issue.

The purpose of Ivan is to help e-NABLE (who make the 3D printed prosthetic
hands for kids and adults as well) to branch out in a new direction of
serving handicapped (or differently abled) people.  My vision is to have a
variety of helper robots stationed in a home for doing a few different
challenging tasks (or helping out anyway).

Ivan is designed to be high in 3D printed content and low in other content
(motors, electronics, software, and fasteners).  Also the plan is for Ivan
to be build able in under $100, hopefully closer to $50 including filament.
By tipping the scale toward print time and away from cost and complexity, we
better meet the requirements of e-NABLE fabricators who can then build the
robot for others affordably and with minimal electronics skills.

Yes, the file size limits appear to be a reason the animations did not play.

Maybe post them to http://imgur.com/ and put a link to your images here?

Let's try this and see how it goes:
