A robot includes a robot arm, a balancer, and a first mounting portion and a second mounting portion. The balancer is pressurized in advance by a predetermined amount of pressure and contracted to a dimension smaller than a predetermined mounting dimension of the robot arm. The first mounting portion and the second mounting portion are disposed on the robot arm to respectively accept a first end and a second end of the balancer so that the first end and the second end of the balancer are mounted on the robot arm. At least one mounting portion among the first mounting portion and the second mounting portion accepts the corresponding end, among the first end and the second end, of the balancer in a direction approximately parallel to a direction in which the balancer is expanded and contracted.

Robot and method for mounting balancer to robot

A robot arm includes a first holder and a second holder. The first holder includes a first base portion and a first distal portion. The first distal portion has a first distal thickness smaller than a thickness of the first base portion. The second holder includes a second base and a second distal portion. The second distal portion has a second distal thickness smaller than a thickness of the second base portion. A first rotator is supported by the first distal portion and the second distal portion. A second rotator is supported by the first rotator. A first bevel gear is provided in the first distal portion. Another first bevel gear is provided in the second distal portion. A second bevel gear engages with the first bevel gear and the another first bevel gear.

Robot arm and robot system

A robot according to embodiments includes a speed reducer, a first shaft, a rotary electric machine, a second shaft, and a brake. The speed reducer reduces and outputs rotation to be input into an input unit. The first shaft is connected to the input unit. The rotary electric machine rotates the first shaft. The second shaft is connected to the input unit. The brake regulates the rotation of the second shaft.

Robot and robot system

An industrial robot includes a hand on which a workpiece is placed, an arm that takes out the hand from a predetermined position of the workpiece and supplies the hand, an up-down moving mechanism connected to the arm by a support member, a pedestal provided at a lower portion of the up-down moving mechanism, and a pendulum stopper provided on a base on which the pedestal turns.

Industrial robot

A transfer robot includes a hand section, a horizontal arm mechanism, and a lift mechanism. An object is to be placed on the hand section. The horizontal arm mechanism is connected to the hand section and includes at least two rotary joints. The horizontal arm mechanism is configured to extend and contract so as to move the hand section along one direction. The lift mechanism is configured to move the horizontal arm mechanism up and down and includes a plurality of link mechanisms disposed on a base member. The horizontal arm mechanism is disposed between parts of the lift mechanism when the horizontal arm mechanism is moved to a lowest position.

Transfer robot

A transfer robot includes a hand section on which an object is placed; a horizontal arm mechanism connected to the hand section, the horizontal arm mechanism including at least two rotary joints, the horizontal arm mechanism extending and contracting so as to move the hand section along one direction, the horizontal arm mechanism being disposed so as to face in an axial direction; and a lift mechanism including a link mechanism that moves the horizontal arm mechanism up and down, wherein the lift mechanism includes at least two sets of link mechanisms disposed on a base member, and wherein the horizontal arm mechanism is disposed between parts of the lift mechanism when the horizontal arm mechanism is moved to a lowest position.

Transfer robot, transfer method, and control method

An articulated robot having a low lowest posture, a long up-down stroke, and such rigidity that the predetermined positional accuracy can be secured is provided. It includes a first arm () which is rotatable about a first horizontal axis (), a second arm () which is rotatable about a second horizontal axis () at the other end of the first arm (), a third arm () which is rotatable about a third horizontal axis () at the other end of the second arm (), an up-down table () which is rotatable about a fourth horizontal axis () at the other end of the third arm (), a fourth arm which is rotatable about the first horizontal axis () and rotatable about the second horizontal axis () at its other end, a first parallel link mechanism (), a second parallel link mechanism (), and a third parallel link mechanism ().
