The Slow Bending Actuator is a basic Pneunet design that is based on the [[soft-robotics:slow-pneunet|Slow Pneunet]] architecture. It is based on a research by Harvard University and the molds on this wiki are designed by [[https://pure.itu.dk/portal/en/persons/jonas-joergensen(8758dd24-d86a-4dab-be44-fa4e9e903141).html|Jonas Jørgensen]] - Researcher at the IT University of Copenhagen. | The Slow Bending Actuator is a basic Pneunet design that is based on the [[soft-robotics:slow-pneunet|Slow Pneunet]] architecture.

- | The bottom half of the top layer cannot be laser cut. | + | The mold can be either 3d printed or laser cut, but the laser cut version would result in a more flat actuator. |

- | From the toolkit website: | + | The air inlet is typical for slow pneunet designs: |
- | <code> | + | |
- | Using a thin metal rod, pierce the end of the actuator, an equal distance from both sides | + | |
- | and about 1/8” (3mm) from the bottom. Aim the rod slightly downwards and don’t push it in too far. | + | |
- | The goal is to reach the central channel without puncturing any of the actuator’s walls. | + | |
