Wolfgang Egger<p>Mein <a href="https://berlin.social/tags/create3" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>create3</span></a> "hello world"</p><p><a href="https://berlin.social/tags/robotics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>robotics</span></a> <a href="https://berlin.social/tags/ros2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ros2</span></a></p>
Wolfgang Egger<p>Today I learned the following: If you have dependencies in a <a href="https://berlin.social/tags/ros2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ros2</span></a> - package, there is a package.xml, where you configure them.<br>Here is the thread in the <a href="https://berlin.social/tags/create3" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>create3</span></a> - forum, where I learned this.<br><a href="https://github.com/iRobotEducation/create3_docs/discussions/283" rel="nofollow noopener" target="_blank"><span class="invisible">https://</span><span class="ellipsis">github.com/iRobotEducation/cre</span><span class="invisible">ate3_docs/discussions/283</span></a><br><a href="https://berlin.social/tags/robotics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>robotics</span></a></p>
Wolfgang Egger<p>Um dem <a href="https://berlin.social/tags/create3" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>create3</span></a> eigene Funktionalität zu verpassen muss man ROS2-packages entwickeln. Die ersten Schritte das findet man im <a href="https://berlin.social/tags/ROS2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ROS2</span></a> Tutorial für Galactic:<br><a href="https://docs.ros.org/en/galactic/Tutorials.html" rel="nofollow noopener" target="_blank"><span class="invisible">https://</span><span class="ellipsis">docs.ros.org/en/galactic/Tutor</span><span class="invisible">ials.html</span></a><br><a href="https://berlin.social/tags/robotics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>robotics</span></a></p>
Wolfgang Egger<p>Ich möchten meinen <a href="https://berlin.social/tags/create3" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>create3</span></a> in mehreren Netzen (WLAN und USB) gleichzeitig betreiben und hab mich gefragt, ob das wohl geht und was ich machen muss.<br>Meine Frage furde im create3-Forum beantwortet.<br><a href="https://github.com/iRobotEducation/create3_docs/discussions/274" rel="nofollow noopener" target="_blank"><span class="invisible">https://</span><span class="ellipsis">github.com/iRobotEducation/cre</span><span class="invisible">ate3_docs/discussions/274</span></a><br>In den create3_docs steht die Antwort.<br><a href="https://iroboteducation.github.io/create3_docs/setup/xml-config/" rel="nofollow noopener" target="_blank"><span class="invisible">https://</span><span class="ellipsis">iroboteducation.github.io/crea</span><span class="invisible">te3_docs/setup/xml-config/</span></a><br><a href="https://berlin.social/tags/ros2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ros2</span></a> <a href="https://berlin.social/tags/robotics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>robotics</span></a></p>
Wolfgang Egger<p>Wenn man auf dem <a href="https://berlin.social/tags/create3" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>create3</span></a> zusätzllche Sensoren und mehr Rechenpower benötigt, muss man ihn mit einem SBC verbinden. Hier ist das für einen Raspi 4 beschrieben.<br><a href="https://edu.irobot.com/learning-library/connect-create-3-to-raspberry-pi" rel="nofollow noopener" target="_blank"><span class="invisible">https://</span><span class="ellipsis">edu.irobot.com/learning-librar</span><span class="invisible">y/connect-create-3-to-raspberry-pi</span></a><br><a href="https://berlin.social/tags/robotics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>robotics</span></a> <a href="https://berlin.social/tags/ros2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ros2</span></a></p>
Wolfgang Egger<p>Leider ist es nicht möglich, das topic /ir_intensity in rviz2 als PointCloud darstellen zu lassen.<br>Ein Versuch führte bei mir darüberhinaus zu <a href="https://berlin.social/tags/ros2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ros2</span></a> - Message-Type - Verwirrung.<br>Das <a href="https://berlin.social/tags/create3" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>create3</span></a> - "Forum" war hier aber sehr hilfreich.<br><a href="https://github.com/iRobotEducation/create3_docs/discussions/267" rel="nofollow noopener" target="_blank"><span class="invisible">https://</span><span class="ellipsis">github.com/iRobotEducation/cre</span><span class="invisible">ate3_docs/discussions/267</span></a><br><a href="https://berlin.social/tags/robotics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>robotics</span></a></p>
Wolfgang Egger<p>Zusätzlich zur Einstiegs-Website gibt es ein "erste Schritte" - Video. Wenn man dem folgt, bekommt man den <a href="https://berlin.social/tags/create3" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>create3</span></a> problemlos so weit, dass man mit ihm über <a href="https://berlin.social/tags/ros2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ros2</span></a> und <a href="https://berlin.social/tags/bluetooth" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>bluetooth</span></a> interagieren kann.<br><a href="https://www.youtube.com/watch?v=UeLHrAvZ_h0" rel="nofollow noopener" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">youtube.com/watch?v=UeLHrAvZ_h</span><span class="invisible">0</span></a><br><a href="https://berlin.social/tags/robotics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>robotics</span></a></p>
Wolfgang Egger<p>iRobot hat eine ziemlich brauchbare Einstiegsseite für ihren <a href="https://berlin.social/tags/create3" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>create3</span></a> erstellt.<br><a href="https://iroboteducation.github.io/create3_docs/" rel="nofollow noopener" target="_blank"><span class="invisible">https://</span><span class="ellipsis">iroboteducation.github.io/crea</span><span class="invisible">te3_docs/</span></a></p><p><a href="https://berlin.social/tags/ros2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ros2</span></a> <a href="https://berlin.social/tags/robotics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>robotics</span></a></p>
Wolfgang Egger<p>Vor einem halben Jahr hab ich beschlossen <a href="https://berlin.social/tags/ros2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ros2</span></a> zu lernen. Nach ersten Versuchen mit einem Kettenfahrzeug-Kit, hab ich mir neulich einen Schulungsroboter bestellt. <br>Vorgestern ist der <a href="https://berlin.social/tags/create3" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>create3</span></a> angekommen.<br><a href="https://berlin.social/tags/robotics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>robotics</span></a></p>
