Did you just grab the animation files off Miximo without your robot?
Or did you send it to Miximo and download the animations?

I usually see this when you send a mesh in A pose and add animation and then grab other animations without skin… The first one works well, but the subsequent animations are for T-Pose but when applied to an A pose character they deform like the one in your image…
I don’t know anything about Rokoko anims…But are they by chance for A-posed mesh? and now you are trying to apply to a T-posed? That would in effect do the same thing…multiply the position from an A-Pose on top of Positions in the T-Pose…

Is it possible for you to place the Mesh in A-Pose and set it as Rest Pose then try another import of the Mo-Cap?
Or share the Blend?

Ok so i rigged the character using Mixamo and set it to a t-pose. Exported that as an fbx and brought it into blender. Then I exported my mocap data from rokoko and that was set as a t-pose as well.
