Assignment 8 : Physical Prototype

Hardware
Arduino is used for sending feedback to the user and also for detecting the colour of the Spray can. Arduino is sent input by using serial communication after detecting the markers and positions. The other hardware is cameras for detecting markers on the can holder and the wall.

Fabrication
FreeCad was used for designing the can holder. It has a circular pocket on top to hold the can and a screw and nut to fix it in place. There is a rectangular pocket to hold the Arduino. The design is very simple and compact.
This comprised of the physical prototype. It was built and tested. Following are the images of the prototype.
