For the robotic projects that you will find on this website (at least on the beginning), I will use Raspberry Pi as the main computer on top of the robot.</p> </div> <div class="post altr"> <h2> <a rel="bookmark" title="8 Tutorials To Solve Problems and Improve the Performance of HC-SR04" href="/robotics/8-tutorials-to-solve-problems-and-improve-the-performance-of-hc-sr04.html">8 Tutorials To Solve Problems and Improve the Performance of HC-SR04</a> </h2> <div class="postmetadata"> <span class="catr"> Fri, 26 Jan 2024 14:16:26 | <a rel="category tag" title="Robotics" href="/robotics/">Robotics</a> | <span class="icon-comments">3 comments</span> </span> </div> <p>There was a time, not all that long ago, when you have been paid several tens of dollars for a sensor able to guide a DIY robot. Now, the average selling price declined to just a few dollars, and the HC-SR04 ultrasonic sensor is the best example. This ultrasonic sensor can be purchased from as low as 1.5 on Amazon if you buy a pack of two. The sensor provides pretty accurate measurements for hard obstacles at a distance of 3-4m.
