Industrial robot

A robot includes a base, a pivot base, an upper arm, and a lower arm. The base is fixed to an installation surface. The pivot base has a pivot base proximal end which is connected to the base such that the pivot base is rotatable around a first axis along a vertical direction. The lower arm includes a first extending portion, a second extending portion, and a connecting portion. The connecting portion has a hollow structure and connects the first extending portion and the second extending portion such that the first arm proximal end faces the second arm proximal end and such that the first arm distal end faces the second arm distal end. The connecting portion includes a reinforcing portion in the hollow structure. The reinforcing portion includes ribs which connect opposed inner walls of the connecting portion and which cross each other.

Robot

A parallel robot includes a base casing, a plurality of arms, and an end unit. The base casing contains a plurality of actuators. Each of the arms is coupled to one of the actuators. The end unit is coupled to the plurality of arms. A communication hole for allowing piping and/or wiring to continue is formed in the base casing at its side facing the end unit.

Parallel robot, robot system, and assembly method for transfer system

A parallel robot includes a plurality of actuators, a wrist portion, and a plurality of arms that respectively connect the wrist portion to the plurality of actuators. The wrist portion includes a base portion that includes a plurality of connection portions respectively connected to the plurality of arms and a rotation member that rotates about a rotation axis located outside an area surrounded by the plurality of connection portions. The rotation member is provided with a through-hole that is formed along the rotation axis.

Parallel robot

A parallel link robot includes a housing, a plurality of driving devices, and a plurality of arms. The housing includes arm coupling openings and a receiving opening. The plurality of driving devices are disposed in the receiving opening of the housing. The plurality of driving devices are attachable and detachable from and in a direction above the receiving opening. The plurality of arms are coupled to the respective driving devices through the respective arm coupling openings.

Parallel link robot and picking system

A parallel link robot includes a first arm including a first joint portion; a second arm including a second joint portion swingably engaging with the first joint portion, the second arm being connected to the first arm to make up a link mechanism; and a biasing mechanism unit which biases the second joint portion toward the first joint portion. The biasing mechanism unit includes a connection member attached to the second arm and the connection member includes a locking portion configured to lock the connection member to the second arm.
