Robot fingers invented by Nam – Photo: N.N.H. |
Two ultra-small robot fingers are the subject of research by Huỳnh Nhật Nam (photo), a 25-year-old PhD candidate at the University of Wollongong, Australia, which has been selected for presentation at the international conference on control held in Turkey in March 2006.
These robot fingers weigh 16mg each, with dimensions of 1mm x 10mm x 0.17mm.
However, what is surprising is not just these minuscule numbers but the ability to carry loads 12 times their own weight, utilizing conductive polymer materials made from polypyrrole instead of traditional motors such as electric or hydraulic systems typically used in small-sized robots. The applications achieve extremely high accuracy, ranging from 1 to 2 micrometers.
Nam’s research results have been published in the international scientific journal Sensors & Actuators. The University of Wollongong has also submitted these results for another international scientific conference in Beijing scheduled for May 2006.
Nam graduated with honors in aerospace engineering from the Ho Chi Minh City University of Technology and was accepted into three universities in Australia for his master’s studies.
In 2005, he graduated with distinction in mechatronics and was awarded a full scholarship to pursue a PhD at the University of Wollongong, which houses one of the top ten polymer materials laboratories in the world. This is also where Nam developed his robot.
Nam plans to continue developing robotic hands with multiple fingers or fingers with several joints to manipulate objects more effectively, and then establish a model for fully automated robot control.
