Abstract:
Disclosed herein is a collection tool configured to independently grasp and cut a tether of a target object for removal from an environment. The collection tool may include a body securable to a robotic arm of a collection robot, a base secured to the body, a plurality of fingers having proximal ends attached to the base, the plurality of fingers constructed and arranged to grasp the target object at distal ends of the plurality of fingers, and a blade coupled to one of the base or body and configured to cut the tether to which the target object is attached while the target object is held by the plurality of fingers.
Pressurizing Housing For A Soft Robotic Actuator

20210039250, Feb 11, 2021

Abstract:
Exemplary embodiments relate to pressurizable housings for a soft robotic actuator. The pressurized housings may be divided into an upper chamber in fluid communication with an internal void of the actuator, and a lower chamber connected to an inlet and an outlet. The upper chamber and lower chamber may be separated by a piston. By supplying a fluid to the lower chamber via the inlet, the piston is moved into the space previously occupied by the upper chamber, which reduces the volume of the upper chamber and increases the pressure in the internal void. This action allows the actuator to be rapidly inflated, and further simplifies the pressurization system and reduces its weight.

Abstract:
Exemplary embodiments relate to improvements in soft robotic systems that permit a soft robotic end effector to be a self-contained system, without reliance on a tether to deliver inflation fluid to the actuator(s) of the end effector. According to some embodiments, a robotic system may be provided including a soft actuator and a hub. The body of the hub may include an integrated pressure source configured to supply inflation fluid through the actuator interface to the soft actuator. The pressure source may be, for example, a compressor (such as a twin-head compressor) or a reaction chamber configured to vaporize a fuel to create a high-temperature pressurized gas and deliver the pressurized gas to the actuator One or more accumulators may receive inflation fluid (or a partial vacuum) from the compressor over time, and store the inflation fluid under pressure, thus allowing actuation over a relatively short time period.

Abstract:
A soft robotic instrument that is capable of changing its form factor (e.g., expanding and contracting) during use to facilitate minimally invasive surgery. The instrument may be formed wholly or partly of an elastomeric, electrically insulating material for mitigating the risk of injuring tissue and for mitigating the risk of electrical arcing during electrosurgery.

B25J 15/00
Abstract:
Robotic grippers have been employed to grasp and manipulate target objects. One task posing relatively unique problems is the handling of meat products, which can be difficult to grasp with a conventional gripper due to the surface texture and malleability of the meat, among other factors. Exemplary embodiments described herein provide robotic grippers having one or more fingers and a plate, the plate optionally providing suction capabilities. The actuators apply a small force to the edges of the grasping target. In suctioned embodiments, an array of suction holes within the plate support the center of the grasping target by applying a light vacuum force at many points along the surface thereof In non-suctioned embodiments, the actuators grip the edges of the grasping target and the plate makes conformal contact with the grasping target to prevent it from folding or otherwise deforming or disintegrating from the gripping force of the actuators.
