A robotics team of six girls from Afghanistan is taking part in an international competition in Washington DC, after clearing visa obstacles that prompted intervention from US President Donald Trump. The team’s ball-sorting robot played in its first game. The team is competing against teams from more than 150 countries in the FIRST Global Challenge. It’s a robotics competition designed to encourage youths to pursue careers in math and science. Like other robots in the competition, the girls’ robot can recognize blue and orange and sort balls into correct locations. The team was twice rejected for US visas.
