Abstract:
Today our world is no stranger to progress in terms of development facilities. Studies
have been conducted to identify and also improve the design of ladder according to
the passage of time. Thus, a ladder has been improved to meet the set standards.
Studies on ladder have given rise to ideas in their creation of "Crawling Ladder" and
we have taken advantage of these ideas by adding some additional features as well as
innovations in improving the use of ladder. There are several procedures that have
been planned and will be followed so that this project can be completed earlier than
planned. The Gantt chart has been designed so that the project runs smoothly. The
findings of the study have shown that many people agree that this "Crawling ladder"
is very useful to do various types of work, especially maintenance work because this
ladder is able to make the work easier and can save time and manpower. The existing
ladder in the market are quite difficult for consumers because they have to go down
the ladder to move the ladder from one place to another. This innovation we designed
can solve the problem because these ladder can move from one place to another
without go down the ladder. In terms of safety, we use the arduino uno as a signal
transmitter, a buzzer as a warning and a motion sensor as a tool to detect the
movement of passers-by near the ladder. When the ladder is in use, if someone passes
by near the ladder, the motion sensor will detect the movement and send a signal to
the arduino, then the arduino will send a signal to the buzzer sounding the alarm to
warn the ladder user.
