2. 1. INTRODUCTION : VIBRO-BOT
• Have you ever noticed that if you leave a cell phone sitting on a
table in "vibrate" mode and it rings, it will move around (and
maybe even fall off the table)? The cell phone has a tiny vibrating
motor inside that makes it buzz. The same motors are used inside
video game controllers to make them rumble. You can use these
motors, along with tiny batteries, to make vibrobots, or tiny
robots powered by vibrations
3. 2. WORKING PRINCIPLE :
• The vibration produced by this motor is an example
of “Driven Harmonic Vibration”. This means there is
an external driving force causing the system to
vibrate.
• The term ‘harmonic’ means that the system is forced
to vibrate at the frequency of the excitation.
6. 4. APPLICATION :
Due to their small size and enclosed vibration mechanism,
coin vibrating motors are a popular choice for many different
applications. They are great for haptics, particularly in
handheld instruments where space can be at a premium:
•Mobile phones
•RFID scanners
•Industrial tools or equipment user interfaces
•Portable instruments
•Medical applications
