d. Flexible Pneumatic Devices
Figure: External and Internal Envelope
Figure: A Flexible Pneumatic Device Using Beans to lift Uneven Objects
Video below, shows using the beans concept, there are coffee beans in the blue envelope..watch closely!
• Principle:
use fluid to grip objects.
• Grip
pressure is proportional to the fluid pressure in the envelope and can
easily be controlled depending on the fragility of the object.
• The
main advantage: to provide maximum grip generality
• Cons: poor positioning accuracy and fast tear
the envelope.
The gripper picks up
an object (such as this coil) by surrounding it with a bag of grains, which is
then pumped free of air.
As the bag tightens,
it conforms to the object's shape, gripping it tight.

ReplyDeleteIs there a specific type of material that can this flexible pneumatic devices can hold?

Dalam prinsip flexible pneumatic device ianya menggunakan cecair untuk mencengkam sesuatu objek..
ReplyDeletebagaimana sistem cengkaman menggunakan cecair itu boleh berlaku?
berapa lama sesuatu objek boleh di cengkam?
flexible pneumatic device bukan menggunakan cecair untuk mncengkam tetapi mngunakan kekacang srta angin sbgai vacum....
DeleteX semestinya guna kekacang, kalau ada angin dan mekanismanya flexible, maka dipanggil flexible pneumatic device...contohnya robot belalai gajah ini http://www.festo.com/cms/en_corp/9655.htm
DeleteContoh end of effector diatas pula cuma menggunakan envelop, iaitu sampul...konsepnya sama, macam jika anda meniup belon di dalam cawan plastik yang ringan...belon akan mengembang, dan mencengkam cawan, dari dalam cawan,,,,, ada juga envelop yang dibuat supaya dapat mencengkam dari luar...
