Learn how to make your own soft robotic tentacle using silicone rubber and some ball point pens!
This project is an easy and affordable way to demonstrate soft robots. The molds only take a few minutes to make and do not require any careful measurements. A single trial size unit of Ecoflex 00-50 (approx. $30) contains enough rubber to make over 40 tentacles. This makes it an ideal project to introduce students to the the field of soft robotics.
