Tactile Sensor, Robot Hand, and Robot
A tactile sensor, comprising: a cover provided so as to cover at least a portion of a base; a first force detection section configured to detect a force acting on the cover in a direction toward the base from the cover; and a second force detection section configured to detect the force acting on the cover in a case in which the cover is further displaced in the direction toward the base after the first force detection section has detected the force acting on the cover.
END EFFECTOR TOOL CHANGER FOR PICK AND PLACE ROBOTIC SYSTEMS
End effector tool changers for a pick, sort, and place robotic system are disclosed. The end effector tool changer comprises an arm attachment portion, a plurality of engagement mechanisms, wherein each engagement mechanism comprises a first part and a second part, and wherein the first part and the second part of the engagement mechanism are selected from the group consisting of a pin and a pinhole; a robotic arm attachment portion, comprising a first plurality of magnets and a first plurality of first parts of the plurality of engagement mechanisms; and a tool attachment portion, comprising a second plurality of magnets and a second plurality of second parts of the plurality of engagement mechanisms. The end effector tool changer has greater mechanical stability, prevents accidental disconnection of the tool, and prevents unintentional rotation of the tool.
Flex-rigid sensor array structure for robotic systems
A flex-rigid sensor apparatus for providing sensor data from sensors disposed on an end-effector/gripper to the control circuit of an arm-type robotic system. The apparatus includes piezo-type pressure sensors sandwiched between lower and upper PCB stack-up structures respectively fabricated using rigid PCB (e.g., FR-4) and flexible PCB (e.g., polyimide) manufacturing processes. Additional (e.g., temperature and proximity) sensors are mounted on the upper/flexible stack-up structure. A spacer structure is disposed between the two stack-up structures and includes an insulating material layer defining openings that accommodate the pressure sensors. Copper film layers are configured to provide Faraday cages around each pressure sensor. The pressure sensors, additional sensors and Faraday cages are connected to sensor data processing and control circuitry (e.g., analog-to-digital converter circuits) by way of signal traces formed in the lower and upper stack-up structures and in the spacer structure. An encapsulation layer is formed on the upper PCB stack-up structure.
Robotic work cell and network
A robotic network includes multiple work cells that communicate with a cloud server using a network bus (e.g., the Internet). Each work cell includes an interface computer and a robotic system including a robot mechanism and a control circuit. Each robot mechanism includes an end effector/gripper having integral multimodal sensor arrays that measure physical parameter values (sensor data) during interactions between the end effector/gripper and target objects. The cloud server collects and correlates sensor data from all of the work cells to facilitate efficient diagnosis of problematic robotic operations (e.g., accidents/failures), and then automatically updates each work cell with improved operating system versions or AI models (e.g., including indicator parameter value sets and associated secondary robot control signals that may be used by each robot system to detect potential imminent robot accidents/failures during subsequent robot operations.
Gripping system and gripping method
An object of the present invention is to grip a bag-shaped object in which a fluid is sealed with stability in a gripping system having a hand mechanism. A tip end portion of a press-in finger portion of the hand mechanism is brought into contact with the bag-shaped object and pressed into the bag-shaped object, and subsequently, when the pressure detected by a pressure detection unit provided on the single press-in finger portion or the pressure detected by any one of the pressure detection units provided respectively on the press-in finger portions reaches or exceeds a predetermined pressure, a gripping operation, which is an operation for gripping the bag-shaped object using at least two finger portions among the plurality of finger portions of the hand mechanism, is executed in a state where the press-in finger portion is pressed into the bag-shaped object.
Systems and methods for determining pose of objects held by flexible end effectors
Systems and methods for determining a pose of an object held by a flexible end effector of a robot are disclosed. A method of determining a pose of the object includes receiving tactile data from tactile sensors, receiving curvature data from curvature sensors, determining a plurality of segments of the flexible end effector from the curvature data, assigning a frame to each segment, determining a location of each point of contact between the object and the flexible end effector from the tactile data, calculating a set of relative transformations and determining a location of each point relative to one of the frames, generating continuous data from the determined location of each point, and providing the continuous data to a pose determination algorithm that uses the continuous data to determine the pose of the object.
Unified Robotic Vehicle Systems and Methods of Control
A robotic system comprising a master robotic system, and a first robotic system comprising a first mobile platform operable to move about a surface, and comprising a first manipulator. The robotic system can comprise a second robotic system comprising a second mobile platform operable to move about the surface, and comprising a second manipulator.

An emblem installation system for installing emblems on a work piece includes an end effector for a robotic arm. The end effector has a base and multiple vacuum gripper modules repositionable along the base in different configurations. The vacuum gripper modules are configured to simultaneously grip multiple emblems and individually release the emblems. An emblem installation method includes applying a force within a first range of forces to the multiple emblems individually and in succession via vacuum gripper modules of an end effector on a robotic arm, with the emblems disposed at a first location, applying a vacuum to the vacuum gripper modules to grip the emblems with the vacuum gripper modules, and moving the robotic arm from the first location to a second location adjacent a workpiece with the emblems gripped by the vacuum gripper modules.

A robotic line kitting system is disclosed. In various embodiments, a sensor reading associated with a force sensor associated with a robotic instrumentality comprising the robotic line kitting system is received. It is determined based at least in part on the sensor reading that a condition requiring human intervention has been detected. A task to be performed by a human worker to correct the condition is scheduled.
ROBOTIC MANIPULATORS
A robot comprising: a chopstick, configured for at least four degrees of freedom of movement, a stiff body of shape and proportions approximate to a pool cue; an electromagnetic actuator, comprising a motor, for each degree of freedom of movement coupled with the stiff body, wherein the functional mapping from each actuator's motor current to torque output along an axis of motion is stored, and used in concert with a calibrated model of the robot for effective impedance control; and a 6-axis force/torque sensor mounted inline between the actuators and each chopstick.
