Abstract

A robot includes a gripping section adapted to grip an object by open and close a pair of finger sections, a moving device adapted to relatively move the object and the gripping section, and a control device adapted to control the moving device to move the gripping section relatively toward the object, and dispose the pair of finger sections in a periphery of the object, and then control the gripping section to open and close the pair of finger sections in a plane parallel to a mounting surface on which the object is mounted, pinch the object between the pair of finger sections from a lateral side of the object, and grip the object with the gripping section at at least three contact points.

Claims

1. A robot system comprising:

a robot; and

a circulation device that circulates a first object, wherein

the circulation device has;

a feeder that supplies the first object;

a first transfer member that transfers the first object supplied by the feeder, the first transfer member being provided at a first height;

a second transfer member that transfers the first object transferred by the first transfer member, the second transfer member being provided at a second height that is lower than the first height; and

a third transfer member that transfers the first object transferred by the second transfer member to the feeder.

2. The robot system according to claim 1, further comprising:

a first stage; and

a second stage on which a second object is placed, the second object being transferable by the second stage, wherein

the first object is placed on the first stage by the robot,

a combined object combining the first and second objects is placed on the second stage by the robot, and

the combined object is transferred by the second stage.
