The Human Eccentric Rotator Device (HERD) is an Earth-vertical rotator device to measure human physiological and cognitive responses. The device can be configured with the human seated upright or laying supine. The radius is up to approximately 8 feet with a spin rate of up to 60 rotations per minute (rpm) to create varying levels of centripetal acceleration. The spin rate is computer controlled with profiles uploaded or adjusted in real-time. Two way audio communication and infrared video allow for subject monitoring by the operators. In the centrifuge configuration, the device can be used to study approaches to creating artificial gravity to prevent astronaut physiological deconditioning.
