Misty, the programmable person robot, is designed to be almost anything an engineer can dream up, from senior companion and wellbeing monitor to friendly pal who will tirelessly play catch with your dog.
Now joining the fight against the pandemic, the engineers at Misty Robotics have defined a new role for her: A highly engaging temperature screening assistant. It is a new, turnkey offering designed for customers who want to screen temperatures at a point of entry to a facility, but who likely do not have the technical background of an engineer the robotics platform was originally created for.
“Misty was ‘purpose-built’ for developers who use the platform to create their own applications, using third party APIs, hardware modifications, etc. Typically, we provide developer support, sample code, and documentation,” said Ian Bernstein, Founder and CTO of Misty Robotics. “But for this application, we started getting inquiries from all sorts of end user companies that do not have technical people. So, we knew we had to develop a solution that was turnkey and came with super easy and clear setup and operating instructions.”
The Misty II Standard Edition already comes loaded with capabilities from a high-resolution camera for face detection and video recording, a built-in array of microphones and text-to-speech detection engine, capacitive touch panels, the ability to play and record audio clips, SLAM mapping and navigation, a neural processing engine, and 3D imaging for AI and machine learning models.
All it needed to become a powerful temperature screening assistant, said Bernstein, was the addition of a thermal camera for taking temperature measurements. Customers plug it into their WiFi network, configure a few settings, and they are up and running.
It was an easy modification: Engineers simply removed some of the mapping and navigation sensors not needed for this application, replacing them with a thermal camera, ideally located in the robot’s visor. The unit comes with a stand containing a black body temperature reference device used to calibrate the temperature sensor and specially designed floor stickers to designate where a person needs to stand when their temperature is taken.
Controlling that distance was important, because the further a thermal camera is away from the object being measured, the more the pixels are spread out over an area, and the lower the image resolution—and therefore the less accurate the measurement. People counter that with more expensive, higher resolution cameras.
“Definitely the thermal camera in this solution was by far our highest cost,” said Bernstein. “Even so, being able to ensure that the person is standing in a very specific spot located 22 inches from the camera, we are able to use a relatively low-resolution thermal array with a 120 deg wide field of view for an accuracy within +/- 0.5 C.”
From a hassle to happy experience
It’s the other features that already come with the platform that makes what the hassle of getting your temperature taken into an engaging, interactive experience.
When an individual enters the facility, Misty uses her voice capabilities to greet the person, ask a few health screening questions, and then directs the person to remove glasses and look at her face, and then does a short countdown. “We don’t actually need that much, but it’s just to make sure we get a good reading,” said Bernstein.
