Beijing: At least five robots at a social welfare centre in China's Zhejiang province remind 1,300 elderly to take their medicine. "The average age of these seniors is over 84," Zhao Huming, vice director of the centre, told Xinhua on Wednesday, adding that the robots were programmed to "remember" medication schedules for seniors and nursing home workers. They send messages to remind them when it is time to take the pills. The robots were developed by Woosiyuan Telecom Technology Co. Ltd. and are in trial operation. The "A-Tie" robots, whose name literally means "iron", are controlled by mobile phone app or touch screens, and can do much more than remind patients to take their medicine. They can be used to make video calls, virtual consultations, or watch television.
