my idea is based around someone who has many DVD's/ CD. there will be a shelf of DVDs/ CD that have been scanned into a database of some kinds using a bar code etc. that represents the name of the DVD/ CD. Then when someone wants a DVD/ CD they type the name into the database of what they want, then a robotic arm will move passed all the DVDs/ CD scanning the bar code etc. looking for the DVD/ CD that has been asked for then it will tell them if the DVD/ CD is there or not and if it is then the arm will grab it and bring it back to the person asking which saves time on the person having to look through shelf's of DVD/ CD for what they want. also love the videos!
