The biggest problem of working alone is the filming for documentation. Every time I move I need to move my camera. So I made a simple Phone’O’Dummy inspired by Iron man’s Dummy/Dum-e.

Phone’O’Dummy is autonomous device used to capture the video. Camera mounted on Phone'O'Dummy Follows the user by detecting their face .It moves in both x-axis and y-axis.

Step 1: Working Principle

Phone’O’Dummy has two motors to move in x & y axis. It is controlled by the arduino microcontroller & motor shield. Phone camera is used to capture the video and it is processed in OpenCV by using Visual Studio 2010(VC++). Using OpenCV we detect the face and when the user moves we send the signal to the arduino board using serial connection(USB). Then arduino board moves the motors accordingly.

<p>Thanks for a cool instructable! I am having a bit of a problem figuring out how you mounted the 2nd arm/motor; could it be possible for you to show it in more detail, either in a vid or through pictures? Thank you very much!</p>
<p>I cut the three small piece of plywood. One is 4.5x7.0 cm and other two are 5.0x8.0 cm. In two pieces i drill a hole to fit the two motors. And in one piece i drill two holes to connect the shaft of both motors using screws.Here's the pic.</p>
<p>great job tejas.</p>
<p>Thanx Abhi</p>
<p>which of the program should i upload to the audrino</p>
<p> upload serialcom.ino into the arduino</p>
This project looks awesome! Do you have any video of it in operation?
<p>I made this yesterday.. I will upload the operational video soon.. Thank you</p>
