PROBLEM TO BE SOLVED: To provide a robot controller which can reduce influence of noise on a control circuit and can be downsized.SOLUTION: The robot controller includes: a motor drive circuit board for driving a motor of a robot at a robot drive voltage; a first relay drive circuit board which has a first relay circuit performing application/interception of a voltage for actuation of a brake braking drive of the robot, and which drives the first relay circuit at a first relay drive voltage lower than the robot drive voltage; and a control circuit board for controlling drive of the motor at a control voltage which is lower than the first relay drive voltage. The motor drive circuit board has a second relay circuit which performs application/interruption of the robot drive voltage for the motor, and a voltage lower than the first relay drive voltage and a second relay drive voltage, is applied to the control circuit board. |
