<p>This little robot can be a lot of things. You can make it as a remote controlled rover with just a couple ESCs and a radio, or you can make it fully autonomous with a Raspberry Pi Zero!</p> <p>Demo Video: <a href="https://www.youtube.com/watch?v=ou1JUl3icZU">https://www.youtube.com/watch?v=ou1JUl3icZU</a></p> <p>Build video: <a href="https://www.youtube.com/watch?v=gO9KHxSDaMg">https://www.youtube.com/watch?v=gO9KHxSDaMg</a></p> <p>Full write-up: <a href="http://thestuffwebuild.com/litero-the-little-telepresence-robot/">http://thestuffwebuild.com/litero-the-little-telepresence-robot/</a></p> <p><strong>Basic assembly requirements:</strong></p> <ul> <li>1x - Pololu 22T track set</li> <li>2x - N20 Gear motor (6V; 180 to 300 RPM recommended; encoder optional)</li> <li>4x - M3 x 15mm machine screws (for motor mounts)</li> <li>5x - M3 x 8mm (for body mounts and battery cover)</li> <li>2x - M3 x 10mm (for body mounts)</li> <li>11x - M3 nuts</li> </ul> <p><strong>Advanced assembly requirements:</strong></p> <ul> <li>Above parts plus:</li> <li>2x - M3 x 10mm (for charger dock bumper contacts)</li> <li>4x - #4 x 1/2" wood screw (for RasPi Zero board)</li> <li>2x M3 x 15mm (for charging dock)</li> </ul> <h3>How I Designed This</h3> <p>Electronic parts selection can be anything you want. Here are a couple recommendations.</p> <p><strong>Basic RC electronics:</strong></p> <ul> <li>2x - 10A brushed ESCs with BEC.</li> <li>1x - 2+ Channel receiver with transmitter</li> <li>1x - 2S LiPo (whatever fits)</li> <li>Optional: FPV camera.</li> </ul> <p><strong>Advanced telepresense electronics (what I used):</strong></p> <ul> <li>1x - Raspberry Pi Zero W</li> <li>1x - Raspberry Pi Camera; 160° FOV with 2 LED modules</li> <li>1x - 16cm FFC Cable for Raspberry Pi Zero Camera</li> <li>1x - Dual L9110S motor driver module</li> <li>1x - 1S Lipo</li> <li>1x - USB 1S LiPo Charge and Protection Module</li> <li>2x - 2-5V to 5V, 2A DC-DC Step-Up Module (One should be enough, But I paralleled two for more current.)</li> <li>Optional: conductive foil tape for charge bumper and dock.</li> <li>Optional: I2C ADS1115 ADC and ACS712 5A current sense module for battery monitoring and stuff.</li> <li>Optional: DIY LM4871 audio amp (for speech synthesis)</li> </ul> Category: Robotics
