    While the novel coronavirus is dangerous for everyone, it is particularly so for the first respond-ere who are being exposed to the illness daily. In the US alone, almost 5,500 nurses, doctors, and other healthcare professionals have been infected with COVID-19. Unfortunately, of these, dozens have succumbed to the disease. Now, hospital workers worldwide may get some relief thanks to Spot, a semi-autonomous four-legged robot developed by Waltham, Massachusetts-based robotics company, Boston Dynamics.

“Starting in early March, Boston Dynamics started receiving inquiries from hospitals asking if our robots could help minimize their staff ’s exposure to COVID-19,” the company writes in a blog post. In response, the company reconfigured (改装）the 3-foot tall robot to operate as a mobile telemedicine platform, enabling healthcare providers to determine a patient’s condition remotely.

The first four-legged robot“dog” was working in the Brigham and Women’s Hospital of Harvard University on April 9, 2020. Equipped with an iPad “face” and a two-way radio that allows for real-time conversation, Spot helps doctors to speak to patients without coming in contact with them.

“With current practice at local hospitals, patients suspected to have COVID-19 are asked to line up in tents outside to answer questions and get initial assessments for temperature. This process requires up to five medical staff, placing those individuals at high risk of being exposed to the virus,”Boston Dynamics explains.“With the use of a mobile robot, hospitals are able to reduce the number of necessary medical staff at the scene and conserve their limited PPE (personal protective equipment) supply.” The company says the doctors can even use Spot to talk to patients from the safety of their own homes.

Though Spot has already proved extremely helpful, the robotics manufacturer believes it can be even more so. The engineers are currently working on“teaching” the robot to perform tasks like temperature checks. The company is also developing new technology that will allow Spot to aid in the disinfection (消毒)of hospitals as well as other public areas.
