Ayunkowi biped robot

prusaprinters

<p>Robot, inspired by Bob and Zowi with bluetooth functionality to be controlled from an Android phone.</p><figure class="media"><oembed url="https://www.youtube.com/watch?v=9TJ12Z6TNDI&amp;t=1s&amp;ab_channel=Ayunken"></oembed></figure><p>You need, printed parts and electronics:</p><p>4 x 9g servos</p><p>micro controller of choice (Arduino)</p><p>battery (4x AAs)</p><p>HC-SR04 - ultrasonic ranging module</p><p>HC-05 - Bluetooth module</p><p>For now it is a prototype, and still a lot of things to improve:</p><p>-&gt; Add the LED array.</p><p>-&gt; Add a new base with support for standard batteries</p><p>Version of Bobwi with all parts modified to fit SG90 servos (already had them) and an 8x8 LED array with MAX7219 driver (to use 6x5 slab as the original Zowi) and buttons and switch on the back. When using the SG90 plastic I preferred to use the adapter rods so that the joints are better fixed.</p><p>I have modified Ayunkowi's housings and legs to make them more resistant.</p><p>I have reinforced the supports of the servos (SG90) in the body because they broke easily,</p><p>I have made the legs shorter and more resistant.</p><p>I have redesigned the head so that it fits the proximity sensor and is fixed, as well as I have put a support for the Bluetooth card and the keypad.</p><p><br>&nbsp;</p><figure class="media"><oembed url="https://www.youtube.com/watch?v=qKfupQ_7ARE&amp;ab_channel=Ayunken"></oembed></figure><p>At the top there are 4 supports for the Arduino shield.</p><p>The head is higher than normal (7mm) so that 2 18650 batteries enter on top of the servos so that you do not have to disassemble the robot when changing batteries.</p><p></p><p>To charge it, it uses a plate from a power bank with 5V 2A output, from the positive it goes through the switch to then go to any 5V pin of the shield. The negative to any GND pin of the shield.</p><p>&nbsp;</p><p><strong>Otto DIY invests lots of time and resources providing open source code and hardware,&nbsp;</strong><br><strong>please support by purchasing our great robotics kits from </strong><a href="https://store.ottodiy.com/"><strong>our website in this link</strong></a></p><h3><strong>or at least give us a ❤️ like and share…</strong></h3><p>&nbsp;</p><p>Be a part of this friendly community of robot builders, teachers and makers.<br>Welcome to our <a href="https://builders.ottodiy.com/">Otto Builder community</a>!</p>
