The elderly would not use these robots on their own accord, so they needed someone to help them set up the program. After Tan Rou set up the program, she instructed the people not to touch the buttons on the robots at will or destroy the robots. Otherwise, they would not be able to get the money.
That's right, this experiment was expensive. The lives of the elderly were relatively difficult. If it weren't for money, they wouldn't have volunteered.
Once they heard that they wouldn't be able to get money if they damaged the robot, they would definitely cherish the robot; at least they would let the robot work for a while longer. This would eliminate the old evil people. If the old people deliberately came in to cause trouble, it would affect the results of the experiment.
Fortunately, the old people that Zhuang Liu found were more obedient. Only a few old people liked to torment the robot and deliberately mess with it.
