OmniWorm: An Omni-directional Inchworm made from scrap

All right, my robot is complete! It is an omni-directional robot that is also capable of inchworm-like movement. It is made from cardboard, dowel rods, and hot-glue. If you want to see how it is made, then check out my instructable!

Basically, this is a continuation of this project (which is now a dead pile of cardboard). Omniworm has two wheels beneath and two wheels on either side. When the sides are folded up only the bottom wheels move (tilt sensors). When it unfolds, the side wheels take the bottom wheels off the ground and become the main drive wheels. However, the fun does not stop there! Omniworm can also move like an inchworm (forwards/backwards) thanks to its "tail," or the top of the box, being able to unfold and scoot the "worm" along. If only it could inch more efficiently...

Hey Drew,

It would probably be good to eventually transition to different materials.  It’ll help when you want to put your robots on your resume.  As will good documentation (as already mentioned)

Here is the PVC that I have used on many projects: http://www.interstateplastics.com/plastic-sheets-details.php?sku=PVCWX&thickness=0.118&dim2=24&dim3=48&src=adwordspla&utm_source=adwordsfroogle&utm_campaign=adwordsfroogle&utm_medium=na&utm_content=plastic+sheets-PVCWX&gclid=CIbgjaXqnr4CFdSMMgodnz8Axg

(I recomend the .25")

Also, after my rescue robot lost a wheel at competition, I’ve tried to use screws and brackets for attaching everything now.  The thicker PVC is nice because you can drill into the side of pieces to make right-angle connections so long as you first drill a pilot hole.  

Thanks for the

Thanks for the reccomendation!

I started building this robot using PVC. However, my origional design became too heavy. I redesigned it and used cardboard since I was out of PVC.

I’ll really have to start using screws though.
