Soft robotic actuators

This invention describes a flexible robotic "muscle" that moves when air or fluid is pumped into it. It works by having internal channels within a molded body, where one part of the body is designed to be stiffer and thicker, while another part is thinner and more flexible. When pressurized, the flexible part expands, causing the entire device to bend or actuate in a controlled direction.

Why it matters: Since 2016, advancements in multi-material 3D printing and sophisticated silicone molding techniques have made fabricating complex soft robotic structures with precise strain-limiting features more accessible. This could simplify the creation of these actuators and enable more intricate designs.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom silicone molding, precise material properties.
