Anki Vector Fork Attachment

I have 2 of the little Anki Vector Robots and there is an Android App where you can control these little robots manually, this is after getting Wirepod onto your computer or Android phone.You can control direction, see the camera view, raise and lower the grab, and move the head up and down etc.These forks I have designed and printed add another dynamic to the Vector Robot, and simply clip onto the existing claw as its called, you align the forks with the claw, and just bend the clip so it grips
