Abstract

To provide a robot controller configured to reliably receive data from a robot even when there is a shield. A robot controller receives a signal transmitted by a wireless device mounted to a robot that is a control target. The signal includes data of an operating state of the robot. The robot controller includes: a first receiving unit that receives the signal including the data from the wireless device; a transfer unit that, in a case in which the signal received by the first receiving unit is a signal from other robot not to be controlled, transfers the signal to other robot controller controlling the other robot; a second receiving unit that receives the signal transferred from the other robot controller; and a signal processing unit that processes the signal received by the first receiving unit and/or the signal received by the second receiving unit.

First claim

What is claimed is:

1. A robot controller that receives a signal transmitted by a wireless device mounted to a robot that is a control target, the signal including data of an operating state of the robot, the robot controller comprising:
a first receiving unit that receives the signal including the data from the wireless device mounted to the robot;
a transfer unit that, in a case in which the signal received by the first receiving unit is a signal from other robot not to be controlled, transfers the signal to other robot controller controlling the other robot;
a second receiving unit that receives the signal transferred from the other robot controller; and
a signal processing unit that determines whether or not the signal received by the first receiving unit has an outlier value exceeding a predetermined allowable variation value, and upon determining that the signal received by the first receiving unit has the outlier value, determines whether or not the signal received by the second receiving unit has the outlier value, wherein the robot controller controls the robot using one or more of the signal received by the first receiving unit not exceeding the predetermined allowable variation value and the signal received by the second receiving unit not exceeding the predetermined allowable variation value.

2. The robot controller according to claim 1 , further comprising a teaching operation panel,
wherein the first receiving unit is detachably connected to the teaching operation panel.

3. The robot controller according to claim 1 , wherein the transfer unit transfers the signal including the data of the operating state of the other robot received by the first receiving unit to the other robot controller controlling the other robot via a wire.

4. The robot controller according to claim 1 , wherein the signal processing unit performs, in a case in which signals are received from a plurality of other robot controllers by the second receiving unit, averaging processing on the signals received from the plurality of other robot controllers.
