The Development of Motorized Eraser as Whiteboard Attachment aimed to design and
build a Motorized Eraser as a Whiteboard Attachment that could be used everywhere
teaching takes place. It is portable, height-adjustable, attachable and removable from a
specified 8 by 4 foot Whiteboard. It is made up of many essential components, including
a steel tubular square bar that serves as the frame, a flat bar with three feetof Eraser and
detachable fiber clothing that serves as the eraser, a limit switch for both ends, a Dc
motor with 40 RPM, and a 12-volt battery for power supply, with a backup battery. The
rubber belt is used to synchronize the Whiteboard Attachment Mechanism with the
movement of the bearing. For safety, the panel box has a primaryswitch, a toggle switch,
and a power male female connector. The prototype was evaluated by 20 students and
professors. The portable eraser for whiteboard is intended to improve processing speed,
accuracy, safety, dependability, aesthetics, and economies. It cuts down on the time spent
manually erasing whiteboard marks. It's also portable, so you may move it from one spot
to another. The prototype, however, does not erase all of the whiteboard markings.
According to the evaluation's numerical results, each respondent rates the utility, beauty,
workability, durability, economy, and, finally, safety. They offer us a rating ranging from
1.00 to 5.00, with an average mean of 4.50.
