The CSIR-CMERI in Durgapur hasdeveloped a low-cost robotic device that can be used for collecting swab samples of people having symptoms of coronavirus, besides treating COVID-19 patients.The 'Hospital Care Assistive Robotic Device' will be very helpful for frontline healthcare workers who are treating COVID-19 patients, said professor Harish Hirani, the director of CSIR-CMERI (Central Mechanical Engineering Research Institute).It will help them in delivering services while maintaining social distancing, reducing the chance of them getting infected, he said.The cost of the device is less than Rs 5 lakh and the weight is not more than 80 kg, making it easy to use and affordable for healthcare facilities, Hirani said.The device, which has a video call facility, can also be used in providing food to the patients.The device can be naviagated through automatic and manual modes, and needs to be monitored by a nursing booth with a control station."It will be able to transport food items, medicines, testing equipment, files, personal protective equipment in a comprehensive sterilised environment," Hirani said.A spokesperson of the institute said the device can function in a range of 0.5 km and has a battery life of four hours."The clinical trial of the device has been successful. We will be ready if healthcare facilities and governments show interest," he said.
