Redmine Task #1907 (Assigned): Check speaker magnet interference with IMU/Compasshttps://roboticsclub.org/redmine/issues/19072011-11-07T21:48:08ZDan Shopedshope@andrew.cmu.edu
<p>Will placing a small speaker near the compass (less than 1" away) cause interference due to the magnetic fields?</p>
<p>If so, how can we mitigate this? - Calculations, numerical values of separation, etc.</p> Bug #1806 (Wontfix): Gumstix Memory Changehttps://roboticsclub.org/redmine/issues/18062011-10-11T16:05:34ZDan Shopedshope@andrew.cmu.edu
<p>FYI, new Gumstix boards have changed hardware<br /><a class="external" href="http://www.gumstix.org/hardware-design/product-changes-known-issues-a-eol/66-product-change-notices/196-2011-product-change-notices.html">http://www.gumstix.org/hardware-design/product-changes-known-issues-a-eol/66-product-change-notices/196-2011-product-change-notices.html</a></p>
<p>The current image will not boot on these devices. Find out what we need to do to make the new hardware bootable.</p> Task #1798 (Assigned): Mechanical Work Loghttps://roboticsclub.org/redmine/issues/17982011-10-09T07:57:04ZDan Shopedshope@andrew.cmu.edu
<ul>
<li>Create undercut latch for hood (center, recess on front lip)</li>
<li>Increase height of hood scoop (aesthetic)</li>
<li>Model hood/switch as multibody part so changes to hood geometry propagate to buttons
<ul>
<li>Use offset surface so "1" and "2" cuts are constant distance from top surface</li>
<li>Create "V" pivot on button piece, and corresponding "V" cutout on hood</li>
<li>Create a slide-on locking piece to prevent button from falling out of hood</li>
</ul>
</li>
<li>Check wiring clearances inside rear chassis - some difficulty assembling right now<br /><del>* Change ScoutFly fasteners (4) to small thread forming screws, check clearance with headlights</del><br /><del>* Design triangular number flag on Sonar stem</del><br /><del>** Print a paper label and slide in one side, wraps around all 3 sides</del>
<ul>
<li>Label should have number (ex "101") AND allocation for naming (ex "Mr. Bickles")
<ul>
<li>name in small font, need to determine character limit, number in large font</li>
</ul></li>
</ul></li>
</ul> Enhancement #1797 (Assigned): Design SmartFly Smart Acessory Reference Boardhttps://roboticsclub.org/redmine/issues/17972011-10-08T03:34:26ZDan Shopedshope@andrew.cmu.edu
<p>Based on Arduino Pro Mini (schematic) - see <a class="external" href="http://www.roboticsclub.org/redmine/projects/colonyscout/wiki/ECESmartAccessoryRefDesign">http://www.roboticsclub.org/redmine/projects/colonyscout/wiki/ECESmartAccessoryRefDesign</a></p> Enhancement #1796 (Assigned): Audio Command & Output Accessoryhttps://roboticsclub.org/redmine/issues/17962011-10-08T03:01:36ZDan Shopedshope@andrew.cmu.edu
<p>Microphone + Speaker output, possible use a speech generation chip and/or voice recognition chip OR load software onto gumstix. Talk to ScoutFly over I2C and relay audio samples/recognized commands, provide verbal output for user feedback.</p> Task #1793 (Fixed): Create mockup for Cliff Sensor Testinghttps://roboticsclub.org/redmine/issues/17932011-10-07T08:57:56ZDan Shopedshope@andrew.cmu.edu
<p>Build a mock Scout (or provide dimensions to MechE team) that holds (3) cliff sensors for testing.</p> Task #1789 (Fixed): Test Cliff Sensorshttps://roboticsclub.org/redmine/issues/17892011-10-06T06:01:56ZDan Shopedshope@andrew.cmu.edu
<p>Option 1:<br />Wire cliff sensors directly to LEDs, move across different surfaces and record behavior (false positives, false negatives, etc)</p>
<p>Option 2:<br />Wire cliff sensors into a microcontroller, also wiring in IR reflectance sensors as a control, and log values while moving across different surfaces</p>
<p>Option 3:<br />Scrap cliff sensors :)</p>
<ul>
<li>For all tests there should be (3) cliff sensors assembled onto a fake Scout model that holds the sensors in the proper orientation and relative positions, elevated above the ground like on a Scout.</li>
<li>A detailed log should be maintained to figure out activation patterns and potentially troublesome surfaces (high rate of false positives).</li>
<li>Test on any reasonable floor surface - concrete, glossy tile, white tables, plywood, wood flooring in the TV lounge, etc.</li>
</ul> Task #1777 (Fixed): Parts Order for Fall Prototype Testinghttps://roboticsclub.org/redmine/issues/17772011-10-03T18:44:21ZDan Shopedshope@andrew.cmu.edu

<p>from kwoo:<br />"Just swap out the part in the schematic and put them in the right place on the layout<br />you need to make the part correctly but you can make the hole plated and connected to the ground layer</p>
<p>then with any metal screw the chasis will be grounded so any shorts should be less disastrous and we get a free big ground plane"</p> Task #1381 (Fixed): acquire ATMega 128RFA1 chipshttps://roboticsclub.org/redmine/issues/13812010-08-28T02:35:19ZDan Shopedshope@andrew.cmu.edu
