2. 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.

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

4. Environmental Solutions Minimize the PCB board size and trace size PCB size ： 160cm* 100cm Dual cell charge management controller Recycle: PCB, battery, other components online website such as greenergadgets.org

5. Ethical Concerns Safety Battery safety : with different voltages, temperatures User safety: children and pets Wrong IR data Bluetooth connection

6. Ethical Solutions Proper warnings Pop-up warnings User Manual : speed, Bluetooth range Wide range testing Different temperatures, humidity Time delay
