Answers.Text: Thanks for the answer, maybe the other two pieces are made by third-party companies and thus are not official LEGO pieces. So these two pieces can't be used in FLL competitions...?

Comments.Text: Well, the red piece is for sure a LEGO piece and fits perfectly with the transparent one. Maybe is a piece made by some third-party company. Can it be?

  It looks like there are three individual pieces.
  
  1. A small metal ball (Probably not LEGO)
  2. A translucent connector (Probably not LEGO)
  3. A red [LEGO Technic Cross Axle (6538)](http://brickset.com/parts/4125189)

  The red piece seems to share the same amount of ridges ridges (three) and seems to be a good match in size and colour. I'm not familiar with this connector being used in this manner, I'm fairly sure the other two pieces are not LEGO.
