In the figures, which depict example embodiments:
In an aspect, a system for deploying a collaborative robot in a glovebox is provided. The system may be developed to deploy a collaborative robot (i.e. a robotic arm) into a glovebox (e.g. an alpha glovebox) on a nuclear licensed site. The system may be implemented to augment an existing glovebox with a collaborative robot which may reduce the risk of accidental exposure to material in the glovebox as a user is not required to manually reach into the glovebox.
The system may reduce risk to operators of gloveboxes by providing a remote system that will substitute a physical human interaction in the glovebox with a robotic twin of the operator. The system may be controlled remotely which may mitigate exposure risk to users when the content of a glove box contain hazardous material, e.g. material that gives off gamma radiation, which is potentially hazardous to a user even when contained in a glovebox.
While embodiments of the invention are described in relation to nuclear technology, the example systems, methods and/or devices described herein may be adapted and/or implemented for use in any glovebox used in research, industrial, pharmaceutical, and/or chemical operations. In some embodiments, the example systems, methods and/or devices described herein may be adapted and/or implemented for use in any application or environment where it may be beneficial to physically isolate/insulate a human operator from objects being manipulated and/or the environment in which those objects are situated.
Because adjustable trolley 2 is rotatable about its longitudinal axis, moveable forward/backward, and configured to raise/lower the collaborative robot 5, the collaborative robot 5 may be inserted into a glovebox in its existing configuration without disconnecting and/or relocating the glovebox from it current application. In some situations, moving a glovebox from its original position may be unsafe or physically impossible.
In an embodiment, system 1 comprises a glove 7 configured to be mounted on port 11 and to receive collaborative robot 5. As shown, in
Collaborative robot 5 may also be configured to be operable with the inner volume of glovebox such that end effector 13 may reach all internal surfaces of glovebox 5 defining the inner volume of glovebox 5.
End effector 13 of the collaborative robot 5 may be positioned at a distal end of the collaborative robot 5. A proximate end of collaborative robot 5 may be mounted to mounting plate 4. End effector 13 may be a 2-digit end effector that may be controlled to perform handling functions including: Remote Vacuuming Decontamination; Remote Contamination Fixative Application with Spray Gun; Remote In Glovebox Alpha Characterisation Survey with Americium Camera; and Remote Handling of Non-Fixed Items for posting out of glovebox.
A camera 14 may be provided on the collaborative robot 5 to observe and shown end effector 13 on display 8. A user may control the movement of collaborative robot 5, and end effector 13, using an input device 29a, b, e.g. gaming controller or other suitable input controller that may configured to move a collaborative robot. In an embodiment, the input controller 29a is hardwired to computing device 1300 to control the collaborative robot 5 on site. In another embodiment, the input controller may be a remote controller 29b which communicates through a network 1301 to control collaborative robot 5.
In an embodiment, adjustable trolley 2 may also be provided with collaborative robot motive force emergency stop button 27. Emergency stop button 27 may be located on the side of adjustable trolley 2 opposing near collaborator robot near the operator and configured to cut power to the collaborative robot in the event of malfunction or operator error.
In some embodiments, then the emergency stop button 28 is activated, the controller is configured to put the collaborative robot in a fault state in which the collaborative robot maintains its position until the fault state is cleared.
Prior to being inserted through port 11 into glovebox 10, collaborative robot 5 may be received within glove 7. As shown in
Several example embodiments of gloves for receiving a collaborative robot are illustrated in
Neck portion may comprise one or more fasteners 36, e.g. loop fasteners or cord and clamp fasteners, positioned radially around glove 7b to couple glove 7b to collaborate robot 5 between camera panel 14a and second tapered should 35. Glove 7b may also comprise one or more fasteners 37, e.g. loop fasteners or cord and clamp fasteners, which may be positioned for coupling glove 7b to an end effector of collaborative robot 5. Fasteners 37 may be positioned adjacent to or generally near the jaw of the digits of the end effector. Fasteners 36 and 37 may be configured to collect excess material of glove 7b such that it does not catch, become tore, or encumber the movement of collaborative robot 5 when received in glove 7b. By fastening material of glove 7b to end effector, the material around the end effector will not catch or interfere with the operation of end effector when in use. Diameter D2 of central portion 33 is configured to allow collaborative robot 5 to turn and move without ripping glove 7b. As shown in

In an embodiment, a glove according to the disclosure herein may be an industrial grade PVC or Hypalon, which may be about 300 μm thick, and camera panel 14a that may be a transparent industrial grade PVC or Hypalon which may be about 250 μm thick.
In some embodiments, the glove includes or is made of a material suitable for isolating, insolating or otherwise reducing exposure between the collaborative robot and the environment and/or objects in the glovebox without restricting motion of the collaborative robot more than is necessary for the robot to perform intended functions in the glovebox.
Gloves according to the disclosure herein may be configured to mount protective sleeve 25. Fasteners 39 may be position adjacent to first shoulder 32 for coupling with an inside surface of protective sleeve 25. Fasteners 39 may be a loop or other anchor point to couple to corresponding fasteners on an inside surface of protective sleeve 25. Protective sleeve 25, when mounted on gloves according to the disclosure herein, may avoid snagging and breach of the glove which could compromise the containment boundary of a glovebox. Protective sleeve 25 may also be provided to protect glove 7 (including 7a, 7b, 7c) from being torn, ripped, or punctured during use. As illustrated in
A collaborative robot 5 according to this disclosure may be deployed in a glovebox, e.g. glovebox box 10 illustrated in
Collaborative robot 5 may also be withdrawn from glovebox 10 for decontamination, disposal, and/or reuse. Collaborative robot 5 may be withdrawn from glovebox 10 by extending collaborative robot 5 into a generally horizontal position such that its cross-section projects within the circumference of port 11; moving adjustable trolley 2 away from glovebox 10; decoupling collaborative robot 5 from glove 7; installing a new glove onto the port; and disconnecting glove 7 from port 11 for disposal. Glove 7 may be disconnected from glovebox 10 by decoupling its O-ring from port 11. Collaborative robot 5 may be serviced and/or decontaminated by a suitable method selected based on the hazardous material collaborative robot 5 handled. In another embodiment, glove 7 may maintain its sealed connection with port 11; collaborative robot 5 may be withdrawn from glovebox 10 by extending collaborative robot 5 into a generally horizontal position such that its cross section projects within the circumference of port 11; and adjustable trolley 2 may be moved away from glovebox 10 to withdraw collaborative robot 5 from glove 7 and glovebox 10. After being serviced and/or decontaminated, the collaborative robot 5 (or a new collaborative robot 5) may then be inserted back into glove 7 and glovebox 10.
