Export a Unity model into C4D

So, i've started to play with unity today, and i downloaded a few assets, and the one that i most liked, (space robot Kyle) inst animated, and it is a full object (arms and legs are all into one single object), so i would like to know if theres any way for me to model it walking, punching, etc, on unity, or any way for me to export the model into cinema 4d so i could animate it there...

 

Robot Kyle is setup as a humanoid rig.
Humanoid rigs support animation retargeting directly in Unity.
Humanoid animations can be found all over the place, any free mocap animations are humanoid animations, and there are several in the asset store you can download for free and work with.

Go to the learn section and read/listen to content related to humanoid rig, animation retargeting - and everything else you are interested in.

 

i do know to make animations, i did some on cinema 4d, but i realised that robot kyle model was a fbx, wich can be imported by cinema 4D,
but thank you very much for helping me,
