This project investiaged the collaborative construction of fiber structures using a team of non-identical robots. A mobile robot mounted with a spool of fiber collaborated with a fixed industrial robot mounted with a simple hooking end effector. The mobile robot is able to move an unlimited distance but only on a 2D plane, while the industrial robot can perform complex 3D movements but only within a limited envelope. Together, the two robots deposited a continuous strand of fiber onto pre-fixed anchors in the environment. The two robots communicated via MQTT in order to coordinate their speeds and maintain a constant tension on the fiber.
