Panther Remote On/Off Input

Hardware
1

Hi everyone,

I’m working with the Husarion Panther, and I’d like to use the Remote On/Off Input feature to control the robot power remotely.

From the documentation, I understand that:

  • Applying 3V–12V to pins 7 (+) and 8 (-) for ~1 second:

    • Turns ON the robot (if OFF)

    • Triggers shutdown (if ON)

Implementation Question

What is the recommended way to generate this trigger signal?

  • Can this be controlled directly using the onboard computer (e.g., Raspberry Pi / Jetson Orin GPIO)?

  • Or is it required to use an external board / relay / microcontroller for a safe and reliable implementation?

Also, are there any best practices or reference circuits for this?

Power Behavior Clarification

When triggering shutdown using this input, does it:

  • Fully power off the entire robot (main power cut via PMU)
    OR

  • Only shut down the onboard computer while keeping the rest of the system powered?

I want to confirm whether this behaves like a physical power button (full system power control) or just a software-level shutdown trigger.

Thanks in advance for your help!

Hi,

Can this be controlled directly using the onboard computer (e.g., Raspberry Pi / Jetson Orin GPIO)?

It is already controller with built-in computer - when you login to the built-in computer and send “sudo shutdown” command, it will turn off completely. However, you cannot turn it on again in the same way, because the computer would no longer work.

You could use a GPIO from any User computer to generate this signal and, if this computer has separate power supply, you would be able also to turn the robot on.

  • Or is it required to use an external board / relay / microcontroller for a safe and reliable implementation?

Yes, to fully use this functionality you would need to use a device that is supplied from an additional battery and is able to communicate remotely (or it could periodically turn the robot on and off).

When triggering shutdown using this input, does it:

  • Fully power off the entire robot (main power cut via PMU)OR

  • Only shut down the onboard computer while keeping the rest of the system powered?

It fully power off the entire robot. It behaves like a physical power button. This remote ON/OFF interface is designed to be used with a remote control system, which would have its own radio interface and its own supply power source.
