Our approach is divided into three main parts. The first
part is the obstacle detector that uses an ultrasonic
transducer to detect objects in front of a user. And for
the second part, which is the main control unit with
embedded software design, a microcontroller is used to
calculate obstacle distance, control motor vibration, and
check battery status. The last part is the device implementation
that presents our hardware design, the main
components, and device specifications.
