    V2 robot power-up connected to Wifi (green LED) no activity: RP3 heats up in air conditioned office:

    67 Celsius after a few minutes with no movement and no fans running.  Reaching 71C after an hour.

    Turn off [learn mode] {engage torque & start fans} CPU temp drops to 59.

    Rasperry Pi fan should probably always be running.

    We have disabled all fans on Niryo One during learning mode so the robot doesn’t make noise. It can be helpful to know whether the robot is in learning mode or not, but the main reason is that the noise gives you headache when you are working in a not-so-noisy environment 🙂

    Usually the Raspberry Pi should not reach more than 70°C. But if it happens in your case, you can change this file directly on the Raspberry Pi, and reboot.

    You can replace the set_fans function by:

    def set_fans(self, activate):
    GPIO.output(FAN_1_GPIO, GPIO.HIGH)
    GPIO.output(FAN_2_GPIO, GPIO.HIGH)

     

    This will make the fan in the base always ON. You can also add other fans (there are some available slots) if you want to.

    NiryoOne hardware version 2
    Niryo One Studio : 2.2.0
    Raspberry Pi 3 image : 2.2.0
    ROS : 2.2.0
    11.1 Volt power supply

    Still having problems with Rasperry Pi running hot “Robot Log: Rpi temperature is really high !”
    Maybe have fan control in NiryoOne Studio Hardware Status (next to Pi Temperature)?
    Maybe activate fan whenever high temperature is detected?

    This certainly is because your robot is quite old, one of the first we sent. Now we don’t have this problem anymore.

    If you have an “old” robot (let’s say before 2019), you can add some fans directly on the Raspberry Pi shield (3 fan slots), so you can lower the temperature – standard fan, 12V. Let us know if you have any trouble doing that!
