Preliminary PCB Layout and Design: Team 16Presenter: 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.

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
