“A new interactive design tool developed by Carnegie Mellon University’s Robotics Institute enables both novices and experts to build customized legged or wheeled robots using 3D-printed components and off-the-shelf actuators. Using a familiar drag-and-drop interface, individuals can choose from a library of components and place them into the design. The tool suggests components that compatible with each other, offers potential placements of actuators and can automatically generate structural components to connect those actuators. Once the design is complete, the tool provides a physical simulation environment to test the robot before fabricating it, enabling users to iteratively adjust the design to achieve a desired look or motion.”
