The instructions can further cause the computing device to cause the plurality of grippers to grip the plurality of collection containers, move the plurality of collection containers to the decapper, and de-cap the collection containers.

A joint structure for a robot including a four-link mechanism, in which an elastic member expands and its restoring force increases as a finger is bent, and a distance between a second straight line passing through a center of a second rotation shaft and a fixed point at which the other end of the elastic member is fixed to the third link is equal to or longer than a distance between a fourth straight line passing through a center of a first rotation shaft and a fixed point at which one end of the elastic member is fixed to the second link, the second straight line being perpendicular to a first straight line passing through centers of second and fourth rotation shafts, and the fourth straight line being perpendicular to a third straight line passing through centers of first and third rotation shafts.

The present invention relates to gripping tongs, particularly pneumatically operated gripping tongs. The gripping tongs comprise a housing in which a preferably pneumatically operable linear drive is formed. A first and a second gripper jaw movable relative to each other and relative to the housing, in particular pivotably mounted, are further provided. To be able to detect whether a workpiece (object to be gripped) has been effectively gripped, particularly in the case of miniature gripping tongs of this type, the invention provides for one of the two gripper jaws of the gripping tongs to itself be designed as a sensor and thereby serve to emit a corresponding signal when the gripper jaws of the gripping tongs have gripped a workpiece and/or when the gripping tongs are in their closed state.

The present invention relates to a gripper system comprising fingers. The gripper fingers are connectable to a gripper arm. The gripper fingers comprise a roller configured to spin around its central axis or a ball element rotatable in any direction; a stopper configured to stop and/or prevent the spinning of the roller or ball. The present invention also relates to a method for grasping and displacing an object.

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.
