Abstract
Disclosed are various embodiments or a robotic gripper. A mechanical gripper is affixed to an end effector of the robotic arm. A mount is also affixed to the mechanical gripper. An air nozzle may be affixed to the mount. The air nozzle can include an egress directed towards the mechanical gripper.
Claims12
A system, comprising:
- an articulated robotic arm comprising:
- a mechanical gripper affixed to an end effector of the robotic arm,
- a mount affixed to the end effector of the robotic arm,
- a pressure sensor on an extensor surface of the mechanical gripper, and
- a plurality of air nozzles affixed to the mount, each of the plurality of air nozzles comprising an egress angularly directed towards the mechanical gripper;
- a bag dispenser;
- a computing device in data communication with the robotic arm, the computing device comprising a processor and a memory;
- and
- an application comprising machine readable instructions stored in the memory that, when executed by the processor, cause the computing device to at least:
- direct the robotic arm to position the mechanical gripper into a bag from the bag dispenser;
- open the mechanical gripper inside the bag;
- stop the mechanical gripper from opening inside the bag in response to the pressure sensor on the extensor surface indicating contact with the bag;
- direct the robotic arm to remove the bag from the bag dispenser through movement of the mechanical gripper, with the mechanical gripper inside the bag;
- direct the robotic arm and the mechanical gripper to grip an item through the bag with the mechanical gripper;
- activate at least one of the plurality of air nozzles to blow the bag at least in part around the item;
- and
- deactivate the air nozzle.
