We are making a computer programmed robot that works according to a

The problem is that I have some slippery objects (pencils with
newfangled paint that is very slippery) and they slip out of the
claw.

It is not easy to increase the strength of the claw, so, I was looking
for some soft material that has an adhesive side and provides a lot of
friction on the other side, but NO sticking (not like glue).

Anyone knows what I can buy that would work?

An example of a high friction material are those car cell phone mats
that keep the phone in one place on the car dash.

Thanks

Rubber weather stripping for doors . Comes on different thicknesses and
degrees of stiffness . Or maybe some strips of that cellphone mat stuck on
with double stick tape .


Yeah, I think that you are right, I ordered a cell phone mat

That sounds good. FWIW, a lot of soft grippers are made from silicone,
which is available in a wide range of durometers.

But it sounds like all you need is some foam tape or something like
that. If you want to see what's done in industry, search on SOFT
GRIPPER FOR ROBOT.
