Can I export the motion data of a rigid body?

Question

I have a rigid body simulation in Blender 2.79. The simulation is very simple, a rounded body is rolling and bouncing down on an inclined plane and I would like to process the motion data in another software.

Is it possible to export the position and orientation of the body in every frame? I am a beginner assuming it would require an addon, but I could not find anything useful.

Edit: Assume we have a local coordinate system attached to the body. I would like to export the position and orientation of the local system with respect to the global one. So a possible output would be a text file with 9 columns (x0,y0,z0 positions of the origin of the local system, and at least two direction vectors of the local x and y axes (of course the z axis can be computed later if needed)). The number of lines in the file would be the number of frames computed during the simulation.

1. keyframe your animation

then use this script:

import bpy

obj = bpy.context.selected_objects[0] # of course you could get your object in better ways, i chose this to be quick ;)

for frame in range(1,30): # here you can also get your frame range in a better way...this is just a prototype, how it works, not how to show what's the best way
    
    bpy.context.scene.frame_set(frame)
    print (frame, obj.location, obj.rotation_euler)

possible output:
