An articulated robot includes a pedestal and two or more modules supported by the pedestal. Each of the two or more modules includes a support member, a link member supported by the support member to be rotatable about a first axis, and a first drive unit provided in the link member and for rotating the link member about the first axis with respect to the support member.

Articulated robot and module thereof

A robot includes: a restricting member configured to restrict a horizontal movement of a predetermined workpiece; and a workpiece moving member configured to generate an action for horizontally moving the workpiece. The controller performs a control operation of positioning the workpiece at a stop position in such a manner that: based on predetermined size information of the workpiece and preset stop position information of the workpiece, the restricting member is positioned at a predetermined restricting position included in the stop position for the workpiece, and the workpiece moving member acts on the workpiece and is moved toward the restricting position to horizontally move the workpiece; and the workpiece is brought into contact with the restricting member.

Robot

A self-traveling articulated robot for working in a production factory is provided, which includes a carriage having at least two operation shafts driven by servomotors, respectively, and self-travelable in a two-dimensional plane, a robotic arm supported by the carriage and having at least one operation shaft driven by a servomotor and constituting a joint, an end effector provided to a tip portion of the robotic arm, and a control unit provided in the carriage and for controlling the operation shaft of the robotic arm and the operation shafts of the carriage to operate in cooperation with each other so that a control point defined in one of the robotic arm and the end effector reaches a target position.

Self-traveling articulated robot

Production system including a rail extending horizontally, and an articulated robot that is self-travelable along the rail parallel to an extending direction of the rail. The robot includes a carriage having at least one operating shaft configured to be driven by a servomotor and to self-travel along the rail, a slider projecting toward the rail from the carriage and configured to releasably engage with the rail, a robotic arm supported by the carriage and having at least one operating shaft driven by a servomotor and constitutes a joint, an end effector provided to a tip-end of the robotic arm, and a control unit inside the carriage configured to control the operating shafts of the robotic arm and the carriage so a control point defined in the robotic arm or the end effector reaches a target position by a collaboration of the operating shafts of the robotic arm and the carriage.

Production system

A dual-arm robot includes a first arm and a second arm, each having a first link rotatable about a first axis, and a second link rotatably coupled to the first link and defined with an end effector attaching portion. The first link of the first arm is disposed to be separated from the first link of the second arm in an extending direction of the first axis. Further, the second link of the first arm and the second link of the second arm are disposed so as to be located between the first link of the first arm and the first link of the second arm in the extending direction of the first axis and so that the end effector attaching portions are located at substantially the same position in the extending direction of the first axis.

Dual-arm robot

A miniaturized articulated manipulatorhas a first arm memberA internally provided with two driving motorsand, and a second arm memberB not provided with any devices corresponding to the driving motorsandand capable of being miniaturized. The driving motorsandcan be disposed in common areasat least partially overlapping each other with respect to a direction parallel to the axis of the first arm memberA and can be arranged in a direction perpendicular to the axis. Thus the first arm memberA can be formed in a small axial size. Thus the first armA and the second armB can be miniaturized and hence the articulated manipulatorcan be formed in a short overall length.
