In 2020，many robots took up jobs,giving both humans and animals a helping hand.
A hospital ward treating COVID-19 patients in Wuhan,China,was run entirely by robots.The robots looked after patients with the lightest symptoms（症状），delivering food for people who work in hospital and keeping the hospital clean.This reduced the risk of doctors and nurses catching the disease.Meanwhile,a robot called Ginger led a dance class for those who were well enough to take part.If a patient fell more seriously ill,they were sent to a human-run part of the hospital for more treatment.
In May,a robot dog enforced（强制实施）social-distancing rules to stop the spread of coronavirus in Singapore.Spot,made by U.S.company Boston Dynamics,served in Singapore's Bishan-Ang Mo Kio Park to check that people kept at least one metre apart from each other.The robotdog was controlled from a distance by a human but may one day be able to work by itself.
In June,a teenager in New Zealand won a national science award for inventing a robot that can take out the bins for elderly and disabled people.Thomas James,who is 17 years old,came up with his great idea after an elderly neighbour was told by a doctor not to take out her wheelie bin（有轮大垃圾桶） in case she fell over.The smart machine took the teenager two years to design and build,using Lego models to test his early ideas.
Over summer,a super-cute SlothBot was tested at the Atlanta Botanical Garden in the U.S.Designed by researchers at the Georgia Institute of Technology,the animal-like robot is powered by sunlight and moves slowly along cables between trees,collecting information about its surroundings.The SlothBot's inventor,Professor Magnus Egerstedt,was inspired after observing sloths（树懒）in Costa Rica.By taking a "creature's-eye view" of life in the trees,researchers hope the robot will help protect endangered forest species in the wild.
