Scientists at the IIT-Kanpur have ventured into the world's first robotic hand for the rehabilitation of stroke patients and have finished their tests on it. The device is a two-finger robotic hand (exoskeleton) that uses a four-bar mechanism and has four degrees of freedom (DOF).
Professor Ashish Dutta and Professors K S Venkatesh who have achieved this feat, explain that "The exoskeleton can be used by a patient on the hand. It uses brain signals, with the help of the brain computer interface (BCI) that is worn on the head, and helps paralysed patients to open and close the movement of their thumb, forefinger and middle fingers for physical practice."
The exoskeleton is operated by an MEGA microcontroller of 300 Mhz and powered by a battery. The teachers say that the device will cost around Rs 15,000.
For the exoskeleton, the duo has partnered with the University of Ulster, based in the United Kingdom, and their teacher Girijesh Prasad, who belongs to Gorakhpur. The device has sensors that control the pressure of the fingertip applied by the patient. If the patient can close or move the finger, the device follows the movement passively. If it does not, then the device actively forces the finger to close, while taking BCI instructions using signals.
