This paper presents an automatic walking aid for elderly people. The aims of this research are to study and implement an automatic walker to assist in physical therapy and help the elderly people walk. The automatic walking aid uses an arduino uno R3 microcontroller for the processing. The wheel movement is controlled using a PWM DC motor speed controller, 12 VDC motors and switches. The ultrasonic module HC-SR04 is used to sense when there is an obstacle, and the alarm message together with the alarm signal are sent to the LED lamp and the buzzer. The validation result shows that 1) The walking aid can be controlled via motors and switches. When there is an obstacle, it can alert and signal via the LED lamp and the buzzer. 2) The results from the evaluation forms shows that the satisfaction of 10 elderly people was 4.78 which is a very good level. The automatic walking aid can improve the ease of walking for the elderly. In addition, it increases the walking ability that leads to be more agile in walking. For the elderly people, the walking aid is easy and convenient to use. |
