Meet the robots confronting COVID-19

In China, robots with tank-like tread have rolled down streets spraying disinfectant. In at least one hospital in South Korea, robots are being used to check patients' temperatures and dispense hand sanitizer. In Tunisia, authorities have deployed robots to ensure people are obeying the lockdown.
