Spot Robot

Researchers from Boston Dynamics, of Massachusetts Institute of Technology (MIT - USA) have developed a robot, called ‘Spot’.

They have planned to use it for patients with Covid-19 symptoms.

Important points:-

1.The robot is controlled by a handheld device.

2.It can walk on four legs, similarly to a dog, climbs stairs and can traverse rough terrain with ease and small enough to be used indoors.

3.It can measure skin temperature, breathing rate, pulse rate, and blood oxygen saturation in healthy patients, from 2 metres away.

4.It has four cameras — one infrared, three monochrome.


  • Body Temperature: The infrared camera measures skin temperature on the face.
  • An algorithm then correlates the facial skin temperature with core body temperature.
  • Breathing Rate: When a patient wearing a mask breathes, their breath changes the temperature of the mask.
  • The infrared camera measures this temperature change, enabling researchers to calculate the breathing rate.
  • Pulse Rate & Oxygen Level: When haemoglobin binds to oxygen and flows through blood vessels, it results in slight changes in colour.
  • These changes are measured with the help of the three monochrome cameras, which filter lights of three different wavelengths.
  • Using these measurements, the algorithm calculates pulse rate and blood oxygen saturation.

Benefits of robot:

1.The robot can be deployed in areas where suspected cases of Covid-19 assemble. Healthcare workers can avoid exposing themselves to risk, by manoeuvring the robot to wherever patients are sitting.

2.The robot can also carry a tablet that allows doctors to ask patients about their symptoms without being in the same room.
