Designing of Cost-Effective Human Assistive Robot and Performance Enhancement

This paper represents an assistive robotic technology to assist elderly people who are unable to move frequently and walk properly and also forget to take medicine. The goal is to implement a prototype and test its capability for helping the elder people to make their life easy and live better. The working prototype has been designed for four features. First, it has a heartbeat sensor where doctors or nurses will easily measure the patient's heartbeat rate. The second one is a common box that will open by touch using an obstacle detector which is known as the sonar sensor. Third, an individual patient has an individual box that will open only by punch RFID. And lastly, the moving part of this robot where wheels are used including motors and sensors. This sensor flows the line and reaches the patient in proper time. This proposed robot is a design based on Arduino Uno and Arduino Nano. The proposed human assistive robot provides 96% to 99% accuracy to determine heart rate compared to ECG heart rate for smokers and nonsmoker persons in two different seasons-winter and summer. The prototype is developed to help the elderly people to make their life easy and reduce the nurse's work and make the digital hospital.
