AWR1642BOOST: Where to begin?

Hello,

My previous coworker ordered some mmWave parts to test around with to see if they are useful for for our robot
these include:
AWR1642BOOST
AWR6843AOPEVM
AWR1843AOPEVM

However he left, leaving me with zero documentation.

My question is, are these 3 standalone products? or are they supposed to be connected together?

if the AWR6843AOPEVM andAWR1843AOPEVM turn out to be standalone radars, and not aditions to the AWR1642BOOST,
I also have no idea on how to to read them as they seem to not operate in the online "Out-of-the-box" tool that TI provides.

also, since I do plan on using these for robot navigation, where can I find information on how to read data from these sensors in a place that is not the "Out-of-the-box" web tool?

so far I've been following the mmWave training series (https://www.ti.com/video/series/mmwave-training-series.html#tab-1)
but I am still unsure for the usecase of these 3 products.

Thanks in advance for any help provided.
