Embodiment Construction

[0042] A scale-up procedure for fabricating soft machines from thermoplastic materials is described. The machine includes an elastic expandable (extensible) first layer and a harder, non-extensible second layer thermally bonded to the first layer. The layers may be bonded directly to each other, or they may be bonded through one or more intervening layers. The machine also includes a pneumatic network that is pressurized to actuate the machine. The pneumatic network can be located in the extensible layer or in the non-extensible layer, or in an intermediate third layer between these two layers. The stiffer, non-extensible layer may optionally include a reinforcement layer, such as paper or mesh.

[0043] In one or more embodiments, a soft robotic machine may be fabricated by thermally bonding layers of thermoplastic material. Thermoplastic materials become flexible or moldable above a certain temperature and solidify when cooled. At least one layer is a thermoplastic elast...

Abstract

The present invention relates to a soft robotic device comprising at least a first thermoplastic layer and a second thermoplastic layer, wherein at least one layer is composed of an extensible thermoplastic material; at least one layer is a non-extensible layer; and at least one layer comprises an aerodynamic network, Wherein the pneumatic network is configured to be in fluid contact with a pressurized source, wherein the first thermoplastic layer and the second thermoplastic layer are thermally bonded to each other.

Description

[0001] Cross references to related patent applications [0002] This application claims priority to US Patent Application No. 61 / 978,573, filed April 11, 2014, the contents of which are incorporated herein by reference in their entirety. [0003] Statement Regarding Federally Sponsored Research or Development [0004] This invention was made with United States Government support under Grant No. W911NF-09-1-0476 awarded by the United States Army Research Office. The United States Government may have certain rights in this invention. Background technique [0005] Soft robots using interconnected channels in molded elastomeric bodies have been reported. Soft machines are based on boneless cephalopods, similar to octopuses and squid. They are formed from a soft material with a minimal design and are designed to mimic the movement of cephalopods by pressurizing the soft device with embedded channels. Soft robots can be actuated using pneumatic pressure to subject the robot to a...
