1. Preliminary PCB Layout and Design: Team 16
Presenter: Scott Stack
Project Overview:
A home security robot that is capable of autonomously patrolling a users home in search of intruders. It will also be capable of being controlled manually through a web site.
Uses the Kinect as both a video camera and a 3D depth sensor that will be able to detect human forms.

2. Overall Layout Constraints
Two separate PCBs : One for battery fuel gauge and one main board
Fuel gauge must be powered at all times.
Four separate power supply circuits 3.3V, 5V, 7.2V, 12V
All linear switching regulators that require carful layout
Wide traces for heavy current flow
Isolation of high current circuits from digital logic
12 volt for atom board and Kinect up to a maximum of 3A
7.2 volt for motors up to an absolute maximum of 4A (typical ~400mA)
Enough board space to accommodate external connectors
RS232 header, 0.1” headers, RJ-11 jack, 2 barrel connectors
Pad out unused pins on microcontroller
Main board must be smaller than 10”x10” to fit on chassis
Fuel gauge PCB must be as small as possible
