<p>Raktim: </p> <hr /> <div>This is where I will put all the information regarding RFIDs<br /> <br /> <br /> 1. '''Bought low frequency rfid evaluation kit from Texas Instrument for $284.'''<br /> <br /> &gt; Zhipu and I did some basic tests with the low frequency rfids. We were <br /> interested in determining the max. velocity of the tags relative to the <br /> readers beyond which the reader will not read. We did the experiment using <br /> the vision system and the turn table and got an estimate of about 2 m/s. <br /> Therefore, the max velocity of the robot wrt to the tags could be 2 m/s, if <br /> we use the low frequency tags.<br /> <br /> &gt; We abandoned the low frequency rfids since it could not read more than one <br /> tags at a time. So we ordered the Series 6000- HF-I Mid-Range RFID<br /> evaluation kit from Texas instrument.<br /> <br /> <br /> 2. '''Bought Series 6000- HF-I Mid-Range RFID evaluation kit for $645.'''<br /> <br /> &gt; Preliminary testing (by Nicolas and Raktim) shows we can identify vehicles <br /> with speed greater than 6 m/s. I think higher speeds can be achieved. We <br /> identified that the software causes delays in reading based on the <br /> functionality chosen. Ideally, we would like to write a &quot;thin&quot; reading <br /> software using the .dll files they have supplied. See the Position Teams <br /> main webpage for user manuals and API.<br /> <br /> &gt; The individual readers from TI cost around $180. Bulk rate for TI Readers is yet to be determined.<br /> <br /> &gt; POC for TI rfid is <br /> Kim Knaack Product Specialist Supervisor<br /> Digi-Key Corporation<br /> (800) 338-4105 x1535<br /> Fax (218) 681-3380<br /> kim.knaack@digikey.com<br /> <br /> I think digi-Key is the contractor for TI rfids. They handle all the <br /> shipping and support for Texas Instrument.<br /> <br /> &gt; Alternatively, contacted <br /> Todd Dirks Director of Sales<br /> SkyeTek Inc.<br /> Direct (303)-615-8050<br /> Phone (720)-565-0441<br /> Fax (720)-565-8989<br /> <br /> He sent me the quote for bulk rate for the tags and readers. It is <br /> available as a pdf document.<br /> [http://www.cds.caltech.edu/%7Emurray/wiki/images/5/55/Skyetek_quote.pdf Price Quote for SkyeTek Readers]<br /> <br /> <br /> The tags and readers can be mixed in interms of the manufacturer. As long <br /> as the readers support the tags. So we can buy tags from TI and readers <br /> from Skyetek, for example.</div>
