The robot will turn on and walk a bit, then stop to open the chest and fire the guns... the chest will then close and the robot continues to walk a bit and then repeats as expected, etc. The power on/off switch may need some contact cleaner, but overall it is very cool and works!  See attached Photos and Video!  This does not come with the original box.  It requires two D batteries that are Not Included.  

Thank you for looking!
