In one embodiment of the invention, a counter balanced arm is disclosed including, a first link having a first rotating transmission device, a second link having a first rotating transmission device and a compression spring, a third rotating transmission device coupled between the first and second links, and a cable routed over the rotating transmission devices coupled between the second link and the compression spring. The compression spring forms a tension in the cable to counter balance a load applied to an end of the second link of the counter balanced arm.

A robot arm increases a plurality of arm sections that are turnably connected. The arm sections include a plurality of links and an actuator section that turns the plurality of links. The actuator section includes: a cylindrical cover provided on an outer surface; a motor that turns the plurality of links; a motor frame included in the motor; a reduction gear that decelerates rotation from the motor and outputs a torque; a collar fixed to the reduction gear; and a wire body including at least one of a wire and a pipe. At least a part of the wire body is housed between a surface including a first small body section formed by the motor frame and the collar and a surface including a second small body section of the cylindrical cover.

Methods, systems, and devices for providing treatment to a target site are described. The system may include a guide assembly, an expandable support device coupled with the distal end of the guide assembly, and an operative member disposed on the expandable support device. The expandable support device may be configured to transition between a collapsed and expanded configuration. The expandable support device may be supported by one or more flexible supports aligned in parallel with an axis about which the expandable support device collapses and/or multiple splines arranged in a pattern configured to promote transitioning of the expandable support device between an expanded and collapsed configuration. The guide assembly may be configured to provide torque to the expandable support device. The operative member can include multiple electrodes arranged in parallel to the axis about which the expandable support device collapses.

A horizontal multijoint type robot is so constructed that it comprises a first arm connected through a first joint shaft to a base, a second arm connected through a second joint shaft to the first arm, and a working shaft provided rotatably and movably up and down on the distal end of the second arm, and that the arm length L1 of the first arm and the arm length L2 of the second arm are equal to each other so that the second arm is able to overlap the first arm.

An umbilical member arrangement structure capable of properly arranging an umbilical member in a parallel link robot. A first additional actuator is arranged on a passive link part of a parallel link robot. An Umbilical member is withdrawn from an opening formed on a generally circular bottom surface of a base part, while having a margin, approaches the passive link part, while extending in an intersecting direction with respect to a longitudinal direction of the passive link part, and is connected to the first additional actuator. The intersecting direction means a direction extending at an angle of 70 to 110 degrees, preferably 80 to 100 degrees, more preferably about 90 degrees, with respect to the longitudinal direction of the passive link part.

Systems and methods that facilitate cables to pass through moving, space-constrained joints and conveying power and/or signals to various robotic joint-associated elements utilize a unitary and flat laminated cable slack within the joint to accommodate the relative motion between mechanical elements of the joints. In various embodiments, the cable has multiple insulated sub-cables; each sub-cable is insulated and physically separable from all other sub-cables. Some of the sub-cables are separated from the cable and electrically connected to joint-associated components for conveying signals and power thereto without mechanically interfering with relative motion between mechanical elements of the joint.

An industrial robot of the present disclosure includes a manipulator, a control device for controlling the manipulator, and a connection cable that connects the manipulator to the control device. The manipulator includes a fixed base section, a first motor, a first detecting section, a power supply section, a first casing, and a first power supply cable. The first motor operates the manipulator. The first detecting section detects the state of the first motor. The power supply section supplies electric power to the first detecting section. The first casing stores the first motor and the first detecting section. The first power supply cable connects the first detecting section to the power supply section. The power supply section is disposed in the base section.

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.

A horizontal multijoint type robot is so constructed that it comprises a first arm connected through a first joint shaft to a base, a second arm connected through a second joint shaft to the first arm, and a working shaft provided rotatably and movably up and down on the distal end of the second arm, and that the arm length L1 of the first arm and the arm length L2 of the second arm are equal to each other so that the second arm is able to overlap the first arm.

A robot includes a plurality of lines respectively having connecting portions, which are connected to an outer apparatus, at end portions, and at least one line distribution board to which the connecting portions of the plurality of lines are attached. The line distribution board includes a plurality of line distribution board elements, which can be separated from each other, and to which the connecting portion of at least one of the plurality of lines is attached.
