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.
