Dear ModalAI Team,

we are currently developing a prototype for an indoor inspection drone and had a question regarding the VOXL Mapper.
Is it possible to automatically trigger the Plan to Home function of VOXL Mapper in the event of a failsafe or connection loss?
In other words, is there a way for PX4 to trigger an event in the MPA Pipe?
If this is not possible without significant effort, we are also considering implementing the voxblox algorithm in ROS2 and triggering a return-to-home event from PX4 through ROS2.
Would it be possible for PX4 to trigger such an event in ROS2 — for example, in response to a failsafe condition?

Thanks in advance!

@Vinny Yes, thank you very much!

Hi guys,

I’m planning to use a VOXL FPV ESC and was wondering whether the current sensor detects not only the current drawn by the motors but also the current drawn from the payload connector J2.
Does the payload current get sensed as well?

Thanks in advance!

And is it possible to connect the i/o expander board (M0065) to the VOXL 2 WiFi Add-on board (MDK-M0141-1-01) to achieve a pwm output ?

Dear ModalAI Team,

We are currently trying to control a Caddx GM1 gimbal via PWM using our RC transmitter (TBS Tango 2 with Crossfire). As our flight controller, we are using the VOXL2 running PX4.
We read that it might be possible to generate a PWM signal using the 4-in-1 FPV ESC, which can be controlled via an RC input—could you confirm if this is correct? If not, what alternative options are available for generating a PWM signal?
We are planning to use the ModalAI ESC via UART, as well as the Crossfire Nano RX and a UART-to-USB adapter, which leaves us with no available interface for connecting the VOXL I/O board—would that be accurate?
We are aware that this topic has been discussed in various forum threads, but unfortunately we haven't been able to find a clear solution that fits our setup.
Thank you very much in advance for your help!

@Alex-Kushleyev Thank you very much!

Dear ModalAI-Team,

we are currently working on a drone project focused on inspecting dark or poorly lit environments. Therefore, we would like to know whether it is possible to achieve VIO (Visual-Inertial Odometry) with onboard lighting mounted on the drone. As far as we understand, VIO relies solely on the forward-facing tracking camera, is that correct? Or do downward-facing cameras (like on the Starling platform) also play a role in VIO? If only the front-facing camera is used for VIO, then a forward-facing light source should theoretically be sufficient, allowing us to avoid the complexity of downward illumination.
Additionally, we would like to know if a Time-of-Flight (ToF) sensor can be used to support VIO, which would obviously be beneficial in dark environments.

Thank you very much in advance!
