The Holiday Card Plott3r is a robot built by Sanjay and Arvind Seshan with LEGO Mindstorms that quickly prints and signs holiday cards. Users can select the design by placing a cube in the desired configuration to draw a snowflake, a Christmas tree, or even Santa’s signature.
The Holiday Card Plott3r solves the holiday card crunch by printing and signing holiday cards and dispensing envelopes – entirely with LEGO elements. Powered by LEGO MINDSTORMS sensors and motors, the robot pints three designs – a snowflake, holiday tree and Santa’s signature.
