The face of a graduating student is displayed on a tablet attached to a robot during a “cyber graduation” ceremony at a school on May 22, 2020 in Taguig, Metro Manila, Philippines. Robots represented some 179 graduating students of the Senator Rene Cayetano Science and Technology High School during a graduation ceremony that was streamed online, as mass gatherings remain prohibited in the country under the Philippine government's lockdown to curb the spread of the coronavirus. The robots were developed by alumni of the school's robotics club, which used tablets to display the faces of the graduating students as they “marched” on stage to receive their diplomas. The Philippines' Department of Health has so far reported 13,434 cases of the coronavirus in the country, with at least 846 recorded fatalities. (Photo by Ezra Acayan/Getty Images)
