Requirements:

• The stickers could placed on planes of all 3 axes.
• The device should consist only of materials from the Lego Mindstorms EV3 Kit.
• Must be completed within the 17 hour event

Our team established the additional requirements:

• Has a 100% placement rate -- does not skip over stickers.
• Can be controlled to place stickers at a precise location.

The concept was to utilize a simple motor and create tension on a section of sticker roll, which could create a suitable angle for stickers to be detached from the paper. This is achieved by attaching the end of the sticker roll to a waste paper collector, which rotates and rolls up the waste paper while simultaneously creating tension throughout the roll.  Waste paper is slowly gathered into a second roll and can be removed when filled.
