This week, the First Global Challenge, a highly anticipated robotics competition for 15- to 18-year-olds from 157 countries, ended the way it began — with controversy.
On Wednesday, members of the team from the violence-torn east African country of Burundi went missing. And well before the competition even began, the teams from Gambia and Afghanistan made headlines after the U.S. State Department denied the members visas. Eventually, they were allowed to compete.
The drama marred an otherwise upbeat event focused on kids and robots.
