|
<p>Computer vision on an FRC robot has some problems.</p>
|
|
<ul>
|
|
<li>RoboRIO is not powerfull enough</li>
|
|
<li>NetworkTables is not fast enough</li>
|
|
<li>A TCP connection is great until you lose connection</li>
|
|
<li>mDNS discovery is not reliable on the field</li>
|
|
<li>UDP can skip frames</li>
|
|
</ul>
|
|
|
|
<h2 id="needs">Needs</h2>
|
|
<p>These are the things I need to have.</p>
|
|
<ul>
|
|
<li>Send data from any device</li>
|
|
<li>Recive data on RoboRIO at any time</li>
|
|
<li>Data rate faster than period time</li>
|
|
</ul>
|
|
|
|
<h2 id="wants">Wants</h2>
|
|
<p>These are the things I would like to have.</p>
|
|
<ul>
|
|
<li>Easy discovery</li>
|
|
<li>Threaded</li>
|
|
<li>Simple interface for new programmers</li>
|
|
<li>Fallback in case of UDP issues</li>
|
|
<li>FMS network firewall compliant</li>
|
|
</ul>
|
|
|
|
<p>I am currently working on a protocol for solving this problem, nad will post an update here once it has been tested. Feel free to let me know your thoughts and ideas.</p>
