https://youtu.be/P5tbpXMmv6A This 3D-printed Raspberry Pi-powered Rubik’s Cube solving robot has everything any serious robot does -- arms, servos, gears, vision, artificial intelligence, and a task to complete. If you want to introduce robotics to your kids or your students, this is the perfect machine for it. <P> This one-eyed four-armed giant stands 35cm (14") tall. 70 hours of print time and an entire spool of filament are needed to print it, not to mention over $200 worth of hardware, but once fully operational, it will surely wow your friends and neighbors. Scramble your Rubik's cube, place it in the robot’s grippers, press a button, and then sit back and watch this amazingly smart and stunningly beautiful machine put it back together. Watch the video! <P> This robot is fully 3D-printable. Other that the servos, servo horns, camera, electronics and a few dozen bolts and nuts, it has no traditionally manufactured parts. Absolutely no soldering or breadboarding is required. <P> <b>Printed Parts List</b>: <table border="1"> <tr><th>Item</th><th>Qty</th><th>Print Time (min.)</th><th>Total Time (min.)</th><th>Filament (gr.)</th><th>Total Filament(gr.)</th></tr> <tr><td><b>rcr_arm</b></td><td align="right">4</td><td align="right">186</td><td align="right">744</td><td align="right">54.44</td><td align="right">217.76</td></tr> <tr><td><b>rcr_slider</b></td><td align="right">4</td><td align="right">145</td><td align="right">580</td><td align="right">32.26</td><td align="right">129.04</td></tr> <tr><td><b>rcr_pinion</b></td><td align="right">4</td><td align="right">21</td><td align="right">84</td><td align="right">5.03</td><td align="right">20.12</td></tr> <tr><td><b>rcr_rack</b></td><td align="right">4</td><td align="right">46</td><td align="right">184</td><td align="right">13.96</td><td align="right">55.84</td></tr> <tr><td><b>rcr_corner</b></td><td align="right">8</td><td align="right">55</td><td align="right">440</td><td align="right">15.68</td><td align="right">125.44</td></tr> <tr><td><b>rcr_gripper</b></td><td align="right">4</td><td align="right">38</td><td align="right">152</td><td align="right">7.16</td><td align="right">28.64</td></tr> <tr><td><b>rcr_leg</b></td><td align="right">2</td><td align="right">271</td><td align="right">542</td><td align="right">82.37</td><td align="right">164.74</td></tr> <tr><td><b>rcr_nut</b></td><td align="right">4</td><td align="right">15</td><td align="right">60</td><td align="right">1.65</td><td align="right">6.6</td></tr> <tr><td><b>rcr_long_bolt</b></td><td align="right">2</td><td align="right">88</td><td align="right">176</td><td align="right">6.13</td><td align="right">12.26</td></tr> <tr><td><b>rcr_short_bolt</b></td><td align="right">2</td><td align="right">84</td><td align="right">168</td><td align="right">6.17</td><td align="right">12.34</td></tr> <tr><td><b>rcr_rod</b></td><td align="right">8</td><td align="right">79</td><td align="right">632</td><td align="right">4.96</td><td align="right">39.68</td></tr> <tr><td><b>rcr_clamp_half1</b></td><td align="right">4</td><td align="right">13</td><td align="right">52</td><td align="right">2.98</td><td align="right">11.92</td></tr> <tr><td><b>rcr_clamp_half2</b></td><td align="right">4</td><td align="right">13</td><td align="right">52</td><td align="right">2.91</td><td align="right">11.64</td></tr> <tr><td><b>rcr_camera_holder</b></td><td align="right">1</td><td align="right">132</td><td align="right">132</td><td align="right">37.69</td><td align="right">37.69</td></tr> <tr><td><b>rcr_camera_cover</b></td><td align="right">1</td><td align="right">30</td><td align="right">30</td><td align="right">8.64</td><td align="right">8.64</td></tr> </table> <P> <b>Total Print Time</b>: 4,028 min.
