In the past few months, we have covered a bunch of robots that can help with COVID-19 testing. Researchers from MIT, Boston Dynamics, and Brigham and Women’s Hospital are now measuring patients’ vital signs with Spot robodog.
Spot uses 4 cameras to measure skin temperature, breathing rate, pulse rate, and blood oxygen saturation from a distance of 2 meters. The researchers developed algorithms to use an infrared camera to measure both elevated skin temperature and breathing rate. As they explain:
For body temperature, the camera measures skin temperature on the face, and the algorithm correlates that temperature with core body temperature. The algorithm also takes into account the ambient temperature and the distance between the camera and the patient, so that measurements can be taken from different distances
