Soft Robotic Actuator Without 3D Printing

Harrison Young has returned with another excellent forum post on his experiments in fabricating building soft robots with everyday materials. This time, he's fabricated an actuating tentacle that is able to swing around in a full circle. The tentacle was molded using ballpoint pens and syringes and he's published a detailed guide to making your own over on Instructables.

It's such a simple and straightforward design. This project is something anyone interested in exploring soft robotics could replicate in a weekend with less than $50 in materials. It's a great entry point for experimenting with your own designs.
