Abstract

A robot includes a base and a robot main body. The robot main body includes a plurality of structural members driven by a plurality of actuators. The base includes a housing into which a control cable drawn, a first opening portion provided on a lower surface of the housing, and a second opening portion provided on a side surface of the housing. The first opening portion is configured capable of selectively attaching/detaching either one of a first connector plate including a connector to which a tip end portion of the control cable can be attached and a first lid portion not including the connector. The second opening portion is configured capable of selectively attaching/detaching either one of a second connector plate including a connector to which a tip end portion of the control cable can be attached and a second lid portion not including the connector.

First claim

What is claimed is:

1. A robot comprising:
a base installed at an installation surface of an installation spot of the robot; and
a robot main body arranged on the base swingably around a swing axis line, and including a plurality of structural members driven by a plurality of actuators,
the base including:
a housing into which a control cable drawn from the plurality of actuators is introduced;
a first opening portion provided on a surface on a side of the installation surface of the housing; and
a second opening portion provided on a side surface of the housing,

the first opening portion comprising a first attach/detach part configured to selectively attach/detach either one of a first connector plate including a connector to which a tip end portion of the control cable is configured to be attached and a first lid portion not including the connector; and
the second opening portion comprising a second attach/detach part configured to selectively attach/detach either one of a second connector plate including a connector to which the tip end portion of the control cable is configured to be attached and a second lid portion not including the connector,
the first connector plate is attached to the first attach/detach part of the first opening portion and is positioned at a portion on the side of the installation surface of the base, and
the second lid portion is attached to the second attach/detach part of the second opening portion,
the robot further comprising:
a support portion configured to introduce the control cable into the housing along the swing axis line, and to support the control cable inside the housing so that the tip end portion of the control cable can be directed to any of the first opening portion and the second opening portion;
a motor mounted within the housing, the motor arranged at a position offset from the swing axis line in a first direction being vertical to the swing axis line, the motor being configured to generate a rotation driving force for swinging the robot main body around the swing axis line;
a brake device mounted within the housing, the brake device arranged at a position offset from the swing axis line in a second direction being vertical to the swing axis line and different from the first direction, the brake device being configured to brake or hold rotation of the motor; and
a reduction device mounted on the housing and comprising an input shaft and an output shaft, both of the input shaft and the output shaft being arranged along the swing axis line and having a hollow structure, and

wherein the support portion is disposed inside the input shaft and the output shaft,
wherein the first connector plate is provided with a connector group including the connectors of a same kind, and
wherein the connectors of the same kind are arranged along a circumferential direction with respect to the swing axis line.

2. The robot according to claim 1 , wherein the base is formed of casting.

3. The robot according to claim 1 , wherein the first connector plate is positioned at a portion on the side of the installation surface of the robot.

4. A robot comprising:
a base installed at an installation surface of an installation spot of the robot; and
a robot main body arranged on the base swingably around a swing axis line, and including a plurality of structural members driven by a plurality of actuators,
the base including:
a housing into which a control cable drawn from the plurality of actuators is introduced;
a first opening portion provided on a surface on a side of the installation surface of the housing; and
a second opening portion provided on a side surface of the housing,

the first opening portion comprising a first attach/detach part configured to selectively attach/detach either one of a first connector plate including a connector to which a tip end portion of the control cable is configured to be attached and a first lid portion not including the connector; and
the second opening portion comprising a second attach/detach part configured to selectively attach/detach either one of a second connector plate including a connector to which the tip end portion of the control cable is configured to be attached and a second lid portion not including the connector,
the second connector plate is attached to the second attach/detach part of the second opening portion, and
the first lid portion is attached to the first attach/detach part of the first opening portion and is positioned at a portion on the side of the installation surface of the base,
the robot further comprising:
a support portion configured to introduce the control cable into the housing along the swing axis line, and to support the control cable inside the housing so that the tip end portion of the control cable can be directed to any of the first opening portion and the second opening portion;
a motor mounted within the housing, the motor arranged at a position offset from the swing axis line in a first direction being vertical to the swing axis line, the motor being configured to generate a rotation driving force for swinging the robot main body around the swing axis line;
a brake device mounted within the housing, the brake device arranged at a position offset from the swing axis line in a second direction being vertical to the swing axis line and different from the first direction, the brake device being configured to brake or hold rotation of the motor; and
a reduction device mounted on the housing and comprising an input shaft and an output shaft, both of the input shaft and the output shaft being arranged along the swing axis line and having a hollow structure, and

wherein the support portion is disposed inside the input shaft and the output shaft,
wherein the second connector plate is provided with a connector group including the connectors of a same kind, and
wherein the connectors of the same kind are arranged in parallel with the installation surface.

5. The robot according to claim 4 , wherein the base is formed of casting.

6. The robot according to claim 4 , wherein the first lid portion is positioned at a portion on the side of the installation surface of the robot.

7. The robot according to claim 4 , wherein the connectors of the same kind are all arranged along a straight line in parallel with the installation surface.

8. The robot according to claim 4 ,
wherein the second connector plate is provided with an additional connector group including the connectors of a same second kind, and
wherein the connectors of the same second kind are arranged in parallel with the installation surface.

9. The robot according to claim 8 , wherein the connectors of the same second kind are all arranged along a second straight line in parallel with the installation surface.
