About the project:
This device is a mouth-controlled mechanical grabber for everyday tasks
No such product exists that allows people without the use of limbs to manipulate objects in thier environment.
This simple and elegant mechanical grabber is easy and inexpensive to produce. The success of the initial prototypes had shown many need-knowers what is possible.

Yes, Noam and I were talking the other day and I was telling him that the mouth piece really makes the bottom of my tongue sore (my tongue ring is mostly to blame though lol). I also told him that when I got home, Adam and I re-examined the "type writer" grabber and its concept of opening/closing the grabber by pushing with my tongue is actually quite easy and I bring it up because I don't think we should rule it out as another option for operating the grabber. One thing that is difficult about the 'bite-to-grab" is that in order to get it into my mouth, I have to have my mouth wide open. Also, the spring that opens the grabber gets stuck and so I'm having to use my tongue to open the claw back up (which in turn, hurts my tongue).
Lets see....... I believe that's it. I'll write more when it comes to me

Thank you so much for this detailed feedback. The mouthpiece needs to be redesigned - hopefully when one of us gets the 3D printer we can continue to refine the ergonomics of this so its comfortable.I agree that using your tongue would probably be more comfortable and easy to do - this is def something we should look at.
I would like to try and prototype a hydraulic version where you have a liquid pouch that site in your mouth and when you compress the liquid the grabber operated.
As far as having your mouth wide open - i think this can be fixed by creating a mechanism that has a smaller profile and by using a thinner plastic to mold the mouthpieces.
How is the tension on the spring now? do you think you could handle a tighter/stonger spring? that would make the claw open again without your help.
There is still lots and lots of work to be done. hopefully when we receive a printer this work will continue with more speed.

Kim, you mentioned in private conversations some problems with the current prototype - could you details those so everyone can see and help solve these issues - thanks!!!
