A rubik's snake-like robot that senses different kinds of touch and responds in kind. Can tell the difference between gentle and harsh handling and then generates it's own responses that expressed physically. The robot is composed of a bunch of interconnected modules that each consist of 3d printed shell containing a few capacitive sensors, a battery, a smart servo, a slip ring and a control circuit. Each module is basically it's own robot, and when linked together the units talk to each other and coordinate actions. The length can grow by adding more modules. Current State: Not up to snuff...motors break. homebrew slip rings suck. Would like to improve with better sensing, more dynamic movement, better software. Would also like to chrome it up!
Enjoy this project?

This is really cool, was it 3D Printed on with FDM? Do you have any of the STL or STP files to share, I think this would make a great pet for the office. 

Are you sure? yes | no

Hi Peter, I've done a few versions on different printers. Most FDM, but also tried polyjet, and sls (through shapeways). The one pictured here is sls. I have some more work to do before releasing the files. Will post here when ready.

This robot seems innovative to me, though my experience with robotics is limited.  I compliment you on the sensory and emotional nature of the robot and I'd love to get one for my Mom!  Or better yet make one!  Please see #Ivan the TeamBot


p.s. I heart capacitive sensors!

Hi Les, Thanks for the support. I hope to day. Ivan is awesome...I see the similarities, but your design is very cool with the internal gears.

You should ping curtis.layton for suggestions. This is right in his wheelhouse.
