A robot hand is designed to open or close fingers using a linear actuator disposed in a housing. The robot hand has linear motion shafts extending from inside to outside the housing through guide holes formed in a wall of the housing. Each of the fingers includes a base portion and a tip portion. The base portions are secured to the linear motion shafts outside the housing. The tip portions are bent inwardly from the base portions in directions in which they approach each other and then extend toward tips of the fingers. A sealing member is disposed between each of the linear motion shafts and a corresponding one of the guide holes to hermetically isolate the inside of the housing from the outside thereof. This structure achieves an increased degree of sealing of the housing and is capable of having an increased opening or closing stroke of the fingers.

A fluid powered gripper can include a body, a bore, a first finger, a second finger, and a piston. The body can include a central bore coaxial with a central longitudinal axis of the body. A bore fluid inlet can be fluidly coupleable to the central bore. The first finger can be rotatable about the body. The second finger can oppose the first finger and the second finger can be rotatable about the body. The piston can be disposed in the central bore. The piston can be powered by a fluid to move between a first position and a second position. The first finger and the second finger can be closed in the first position and open in the second position.

A robot hand is provided. The robot hand includes a first and second drive gears rotated by first actuator and second actuators; a first interlocked gear interlocked with the second drive gear to rotate in opposite directions; a second interlocked gear interlocked with the first drive gear to rotate in opposite directions; a first inner link engaged with rotation of the first drive gear; a first outer link engaged with rotation of the first interlocked gear; a first end link connected to the first inner link and the first outer link opposite the first actuator; a second inner link engaged with rotation of the second interlocked gear; a second outer link engaged with rotation of the second drive gear; and a second end link connected to the second inner link and the second outer link opposite the second actuator.

The present application discloses an automated kitchen system comprising a first computer and a plurality of second computers which are connected so that the first computer may communicate with any of the second computers. The automated kitchen system also comprises: a plurality of ingredient containers each configured to contain or store food ingredients; caps configured to close on the ingredient containers; a storage apparatus comprising compartments each configured to store a plurality of ingredient containers and refrigeration mechanism configured to cool the food or food ingredients in the containers of the storage apparatus; transport boxes each configured to contain capped ingredient containers; a transportation apparatus configured to move the transport boxes wherein the transportation apparatus comprises motors and sensors; a cap opening apparatus configured to remove a cap from a capped container wherein the cap opening apparatus comprises motors and sensors; a first transfer apparatus configured to move a capped ingredient container from a transport box to the storage apparatus, and also configured to move a capped ingredient container to a location on the cap opening apparatus, wherein the first transfer apparatus comprises motors and sensors; a cyclic transport apparatus comprising a cycle of container holders each configured to hold an ingredient container; a transfer apparatus configured to move an ingredient container from the location of cap opening apparatus to a position on a container holder of the cyclic transport apparatus wherein the second transfer apparatus comprises motors and sensors; and a plurality of cooking systems. Each cooking system comprises a cooking container configured to hold food or food ingredients during a cooking process, a stirring motion mechanism configured to produce a motion in the cooking container as to stir, mix or distribute food or food ingredients held in the cooking container, wherein the stirring motion comprising motors, sensors, and a stove; a cyclic transport apparatus comprising a cycle of container holders each configured to hold an ingredient container; an unloading apparatus configured to unload food ingredients from an ingredient. The above mechanisms and apparatuses comprise electrical or electronic devices and sensors, which are configured to be connected to the second computers. The first computer is configured to store various sub-programs and other lists that are useful to control the electric or electronic devices in the mechanisms, apparatuses or systems in the kitchen system.

Clamping or gripping device with a main body, with guide portions provided on the main body, with jaws which are movable along the guide portions in a direction of movement, which can be moved between an inner stroke position and an outer end-of-stroke position, the jaws each having a row-of-teeth portion with, in each case, a length extending in the direction of movement, and with multiple pinions, the axes of rotation of which lie in a plane lying parallel to the respective row-of-teeth portions, the pinions interacting with the respective row-of-teeth portion to drive the jaws.

Example systems and methods are described that are capable of gripping objects. In one implementation, a method involves identifying, by a processing system, an object to be gripped at a first location, commanding, by the processing system, a robotic actuator to move a gripper in a first direction so that the gripper makes contact with the object, wherein one or more teeth in a plurality of fingers associated with the gripper mechanically engage the object, and commanding, by the proceeding system, the robotic actuator to move the gripper in a second direction that is substantially opposite to the first direction, causing the gripper to grip the object.
