Through the installation of static digital cameras in different areas at home, IoT robots will go over to the elder’s side once fails have been detected by the cameras. The robots are able to detect their painful facial expression and ask for their conditions. Calls will be made to their family members for help if the elders request that they are in need of assistance or if they lose consciousness. Besides, the system can ask whether the elders have taken medicine on time via voice messages. Their family members will also be informed of their compliance with the drug regimen through SMS messages, which will be uploaded onto the Cloud for reference.
