Soft robotic actuators

摘要

A soft robotic device includes a flexible body having a width, a length and a thickness, wherein the thickness is at least 1 mm, the flexible body having at least one channel disposed within the flexible body, the channel defined by upper, lower and side walls, wherein at least one wall is strain limiting; and a pressurizing inlet in fluid communication with the at least one channel, the at least one channel positioned and arranged such that the wall opposite the strain limiting wall preferentially expands when the soft robotic device is pressurized through the inlet.

主权项

1. A soft body robotic device, comprising:
a flexible molded body having a plurality of interconnected chambers disposed within the molded body, wherein a portion of the molded body is comprised of an elastically extensible material and a portion of the molded body is strain limiting relative to the elastically extensible material, and wherein the thickness of the molded body is at least 1 mm; and a pressurizing inlet that is configured to receive fluid for the plurality of interconnected chambers, wherein the molded body is configured to preferentially expand when the plurality of interconnected chambers are pressurized by the fluid, causing a bending motion around the strain limiting portion of the molded body; and wherein the strain limiting portion has a wall thickness greater than other portions of the flexible molded body.
