Jenny 5 is an (almost) humanoid robot intended to be used mainly for research but also as a human assistant. More details about Jenny 5 can be found at: <a href="https://jenny5.org/">https://jenny5.org</a> or <a href="https://jenny5-robot.github.io/">https://jenny5-robot.github.io</a>.Jenny 5 was inspired by the Johnny 5 robot from the <a href="http://www.imdb.com/title/tt0091949/">Short Circuit </a>movie. This a great movie that anyone must see.Jenny 5 has a mobile platform with tracks, a pliable leg, two arms with 7 degrees of freedom each and one head.All source files (CAD, software etc) for Jenny 5 are freely available on <a href="https://github.com/jenny5-robot">GitHub.</a> All code is released under <a href="https://en.wikipedia.org/wiki/MIT_License">MIT license </a>so that anyone can freely use it in both personal and commercial applications.Jenny 5 is easy and cheap to build. Most components can be purchased from robotics stores. Custom made parts can be printed with a 3D printer. Some aluminium profiles can be cut and drilled with tools available for hobbyists.Materials (excepting the computer) cost about 2500 USD (please see the <a href="https://docs.google.com/spreadsheets/d/1SwaC4woJEvUEqn66lIG9MLYkuADfTsWIQtvDKaCQT1s/edit?usp=sharing">bill of materials </a>for more details).Jenny 5 is designed in <a href="http://www.openscad.org/">OpenSCAD </a>which is a CAD software where you write instructions, instead of using the mouse, to create objects.The platform is driven by 2 DC motors with planetary gearbox controlled by a <a href="https://www.basicmicro.com/">RoboClaw </a>board.The leg is driven by 2 linear motors controlled by a RoboClaw board.Each arm has 6 stepper motors and each joint has attached a magnetic sensor for reading its position. Motors and sensors are controlled by an <a href="https://www.pololu.com/product/3145">A-Star 32U4 Mini</a> board.The gripper is powered by a servo motor. The gripper is connected to the same A-Star 32U4 Mini board as the entire arm. The gripper has attached a webcam used for recognizing objects closed to it.The head has 2 degrees of freedom ensured by 2 stepper motors which have magnetic attached for reading the position. The head has a webcam for object detection and an ultrasonic sensor for distance measurement. All head components, except the camera, are connected to an <a href="https://store.arduino.cc/arduino-nano">Arduino Nano </a>board.The entire robot is powered by 2 LiPo batteries: one for platform and foot and one for arms and head.A-Star / Arduino boards run a specially crafted firmware called <a href="https://github.com/jenny5-robot/Scufy">Scufy </a>which is able to control multiple stepper motors and read a variety of sensors: buttons, ultrasonic, potentiometers, infrared, LIDAR etc.PC software is built around several libraries which send commands, on a serial port, to A-Star/ Arduino boards and to the RoboClaw controller.The robot can be manually controlled by an HTML5 application running within browser on a smartphone. The HTML5 application connects with a server running on the robot. The server is the one that actually execute the commands(move, read sensors) etc. The server is built on a top of a light WebSocket server.Having all these elements, the robot can be utilised in a wide range of scenarios. Here is a short list of things that the robot could do (if programmed correctly):<ul ><li >House cleaning</li></ul><ul ><li >Food preparation</li></ul><ul ><li >Cleaning kitchen table</li></ul><ul ><li >Working in the garden</li></ul><ul ><li >Surveillance</li></ul><ul ><li >Rescue</li></ul><ul ><li >Disaster management</li></ul><ul ><li >Fire fighting</li></ul><ul ><li >...</li></ul>For more details please read the <a href="https://www.researchgate.net/publication/334974417_Jenny_5_-the_robot">technical report </a>about Jenny 5.You can also subscribe to Jenny 5 <a href="https://groups.google.com/forum/#!forum/jenny5">Google group</a>.<div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe frameborder="0" allowfullscreen="" src="https://www.youtube.com/embed/hdJjoeEZpkE" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" style="width: 100%; height: 100%;" data-index="0" data-file-size="0" data-origin="100%,56.25%"></iframe><figcaption contenteditable="true"><div>Jenny 5 - testing the platform</div></figcaption></figure></div><div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe frameborder="0" allowfullscreen="" src="https://www.youtube.com/embed/TEIDooj2Ez0" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" style="width: 100%; height: 100%;" data-index="0" data-file-size="0" data-origin="100%,56.25%"></iframe><figcaption contenteditable="true"><div>Jenny 5 - moving through garden</div></figcaption></figure></div><div class="se-component se-video-container __se__float-none" contenteditable="false" style="width: 100%;"><figure style="width: 100%; height: 56.25%; padding-bottom: 56.25%; margin: 0px;"><iframe frameborder="0" allowfullscreen="" src="https://www.youtube.com/embed/QCJ_H5Qos-U" data-proportion="true" data-percentage="100%,56.25%" data-size="100%,56.25%" data-align="none" style="width: 100%; height: 100%;" data-index="0" data-file-size="0" data-origin="100%,56.25%"></iframe><figcaption contenteditable="true"><div>Jenny 5 - moving arms</div></figcaption></figure></div><figure><img src=https://projects.arduinocontent.cc/8a98c4ce-824e-4cf7-8e24-f2e74f70bb73.jpg /><figcaption>Jenny 5 in garden</figcaption></figure><figure><img src=https://projects.arduinocontent.cc/4fff2c80-2736-4b26-8515-cb6155cfb070.jpg /><figcaption>Jenny 5 and me in garden</figcaption></figure><figure><img src=https://projects.arduinocontent.cc/87bc8065-38e4-43ae-b5a9-c88321b535a7.jpg /><figcaption>Jenny 5 with leg compressed</figcaption></figure><figure><img src=https://projects.arduinocontent.cc/c2b705f8-d041-4c96-a29f-68435c3a62a1.jpg /><figcaption>Jenny 5</figcaption></figure><figure><img src=https://projects.arduinocontent.cc/3368467d-5fe6-4473-a27a-97080b49924a.jpg /><figcaption>Jenny 5 arm (close view)</figcaption></figure><figure><img src=https://projects.arduinocontent.cc/fcfbc218-1eab-40f7-9a93-0c435573e7bc.jpg /><figcaption>Jenny 5 platform and leg.</figcaption></figure><figure><img src=https://projects.arduinocontent.cc/e054312d-9029-47a7-9a38-184286d80f9c.jpg /><figcaption>Jenny 5 arm electronics</figcaption></figure><figure><img src=https://projects.arduinocontent.cc/ead6bb4a-66f2-44c2-9f65-f0b2440bbdce.png /><figcaption>Jenny 5.
