Numbness is something most of us have experienced in extreme cold weather conditions. The loss of sensation and the inability to feel something can set off the most unexpected paranoia and fear in humans. One feels doomed and at a loss and it is almost as if one has lost the ability to communicate with the world. Imagine if a robotic finger could replace this inability to sense in a dire jiffy. Scientists at Syntouch have developed a robot with tactile sensory abilities to differentiate and identify different surfaces and textures. The official name "Biotacs" enables a robot equipped to discriminate between 117 different textures with greater than 95% accuracy. The robot has been able to outperform even human sensitivity in certain conditions.
SynTouch LLC (Los Angeles) and the University of Southern California have developed an advanced tactile sensor modeled after the human fingertip.They hope that this technology and its applications can launch the field of "machine touch." This year the company has sold almost 100 of its Biotac sensors to researchers in the fields of medicine and academics. This is an effort to further explore the navigation and the use of this device in other fields as well.
The Biotac comes complete with human like skin and this can be easily replaced if damaged or torn. The Biotac can be mounted onto a prosthetic hand and the user can handle delicate objects easily and reliably.
The company Syntouch is among the top ten robotic companies in the world. While developing the Biotach , the robot was trained on 117 common materials gathered from fabric, stationery and hardware stores. It was able to intelligently identify the material 95% of the time . Biotach is also trained to detect three kinds of inputs -temperature, texture and force with vibration. The temperature can help it to distinguish metal from glass, texture will help it identify a button from its surrounding panel thereby mimicking the human fingertip. The programming of the Biotach is based on these three inputs. Such technology is called Haptic technology and is currently being developed to enable millions of handicapped people to touch and feel with human dexterity again.
