<p >1000 Behaviors is an experimental framework for observing and evolving the movement behaviors of a robot. Consisting of nine collaborating servo motor segments that are connected by joints, the robot performs its movements based on generated and processed data to find its most optimized behavior.</p><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://player.vimeo.com/video/339519998" 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></figure></div><h3 >Data structure</h3><p >The movement data of the robotsnake are structured in generations, behaviors and units. Each unit is representing one motor and contains the values that prescribe the oscillating movements of the motors. Each behavior is formed by nine motors. And each generation constists of 1,000 of these behaviors.</p><figure><img src=https://projects.arduinocontent.cc/c56b5769-df82-482d-921d-3b3835ab2078.jpg /><figcaption>Installation view</figcaption></figure><p ></p><figure><img src=https://projects.arduinocontent.cc/f111af3b-cc37-4c12-95c5-d6c4a95561b3.jpg /><figcaption>Details of the installation: A 5VDC power supply and an Arduino Mega</figcaption></figure><h3 >Data gathering</h3><p >For each new generation the robot tests all behaviors. By performing the prescribed movements from that behavior in a certain amount of time and in front of an observer. The observer helps the robot evaluating its behaviors by giving each one a quantified rating. Usually the observer is a person who gives this rating based on intuitive criteria.</p><figure><img src=https://projects.arduinocontent.cc/507ee090-7599-489f-a4ce-c583ae3a7f58.jpg /><figcaption>The console, used to rate the behavior afterwards</figcaption></figure><p ></p><figure><img src=https://projects.arduinocontent.cc/04f444cc-d750-49c2-ade9-5898008725ec.jpg /><figcaption>Overview of the behavior: Nine motors, each with three values</figcaption></figure><h3 >Selection process</h3><p >After all tests are completed, the data from the behaviors of the robot are being sorted by their ratings and then mutated and recombined, so that 1,000 new behaviors can then be generated.</p><p >In this process the robot's 1,000 behaviors are consistently evolving, influenced by many observers, the framework, and the robot itself.</p><figure><img src=https://projects.arduinocontent.cc/81871d9e-bfc1-4024-be35-a7b37917043b.jpg /><figcaption>Photo by Nathalie Gebert, at EMAF No. 32, Osnabrück 2019</figcaption></figure><p ></p>
