What if I don’t have a ROS 1 Device?

Future versions of Formant Free plan to support ROS 2 devices as well. Formant Premium currently offers support for ROS 2 devices. There is also an SDK for non-ROS devices that you can use with Formant Premium.

What limitations do I have regarding bandwidth or device limits?

Formant has not set any specific bandwidth or device limits. You are free to use Formant however it best fits your usage. Instead, there are a few account-level defaults chosen for Formant Free accounts. First, all ROS topics will be ingested at most 5Hz. Second, instead of a limit on bytes transmitted, there is a limit of 12 ROS streams you can ingest on your dashboard. Premium accounts have no such limits.

At what frequency does my data get sent to Formant?

Regardless of what frequency your system publishes its data, Formant will send your data at a frequency of at most 5Hz. Streams at a lower frequency will publish at that lower frequency. Formant will take the most recent datapoint at the 5Hz mark instead of interpolating or averaging your data over a window.

Who do I contact if I have a question or problem?

You can contact Formant’s support department at [email protected] Formant cannot guarantee a response time for your request as Premium users have priority support with their accounts.
