Introduction

Who are we?Two second year computer science studentsOne third year engineering student.

What is our project about?A camera operated from a distanceWireless transport of signals

Our goal

Improve human to machine interfaceIntuitive way to control a camera


Use cases

For what?Placed on a remote controlled vehicleUsed to explore remote or dangerous areasGet a clear view from angles people cant reach

For whom?RC pilotsRobot operatorsLaw enforcers observing an areaPeople who want to try new things


Requirements

Large field of viewIntuitive controlsFast and reliable feedbackLight and compactLong range wireless communication


Other solutions

What’s available:Some security cameras have similar featuresMany hobby stores offer this kind of equipment for RC toysMilitary grade version of this is used in fighter pilot helmets

But...SlowLimited field of viewExpensive


Our solution

Still in prototyping phase but has some promising featuresFull range of view (360 yaw, 180 pitch)Continuous rotationRoom for HD cameraLong range


Design: Overview

We have a mounted camera that’s controlled by a remote.Two micro-controllers communicatingOne reads the rotationOther mimics that rotation


Design: Software

Custom libraries written for the Arduino in C++A library to interface with the gyro is provided by the sellerhttp://www.pololu.com/catalog/product/2125https://github.com/pololu/L3GMany of the standard Arduino librarieshttp://arduino.cc/

Performance

How did it perform?Up to 1.6Km range in line of sighthttp://www.sparkfun.com/datasheets/Wireless/Zigbee/XBee-Datasheet.pdfA bit slowNot accurate enoughToo heavy

Future work

What we would like to doBetter sensorsBuilt in video transmitter/receiverBuild a smaller, lighter frameGet a lighter, faster motor


Design: Hardware

Two Arduino micro-controllersOne servoOne stepper motor7,4V 2200mAh battery packStepper control board3-axis gyroTwo xBee pro modulesCustom built aluminum frameCustom built plastic stand
