Abstract

• The Infrarat is an autonomous toy car that will use proximity sensors and a pivoting array of Infrared sensors for tracking a body and to avoid running into objects.

• It will also wirelessly interface with an Android device to receive commands and send the temperature gradient encoding from the IR sensor to be displayed on the device. It will be used in three modes which are follow, run away, and manual control.

Environmental Impact

• Manufacturing PCB fabrication: Chemical etching (heavy metal)• Rechargeable battery Short cell life • Proper Disposal Non-biodegradable components (eg: plastic)

Environmental Solutions

• Minimize the PCB board size and trace sizePCB size： 160cm* 100cm• Dual cell charge management controller• Recycle: PCB, battery, other componentsonline website such as greenergadgets.org

Ethical Concerns

• SafetyBattery safety : with different voltages,

temperaturesUser safety: children and pets• Wrong IR data • Bluetooth connection

Ethical Solutions

• Proper warnings Pop-up warnings

• User Manual : speed, Bluetooth range

• Wide range testing Different temperatures, humidityTime delay
