The Silent Barrage robotic embodiment. (A) Illustration of the Silent Barrage “organism” during its exhibition at the National Art Museum of China (NAMOC), in Beijing. Spatial patterns of action potentials recorded from a dissociated cortical culture are used to drive the robotic body. A video stream of visitors to the exhibition are interpreted by NeuroRighter’s plugin protocol and used to control multichannel electrical stimulation though the MEA, closing the loop around audience members, robotic system, and neural tissue over thousands of kilometers. (B) Audience members viewing the exhibition at NAMOC. Simultaneously, NeuroRighter translated the overhead video feed to stimulation patterns delivered to the culture and then translated resulting neuronal activity patterns to robotic actuation at the exhibit. (C) Photograph of an individual robot and the traces it produced during the NAMOC exhibition.
