## Summary

Kinetic artist Sarah Petkus discusses her work building robotic art installations, including the 'Robot Army' of miniature Delta robots and 'Noodlefeet,' a quadruped robot designed to interact with humans. She explains her transition from illustration to mechatronics at SAIC, detailing how she used Algodoo for simulation and 3D printing for rapid iteration. Petkus also covers the business side of her hobby-turned-company, Robot Army LLC, including their Kickstarter campaign and the challenges of self-promotion as an introvert.
