INTELLIGENT HANDHELD INSTRUMENT FOR MICROSURGERY & BIOTECH MICROMANIPULATION

To enhance human positioning tasks requiring micro level accuracy (e.g. microsurgery and cell micromanipulation). The intelligent instrument will detect motion, distinguish undesired and intended motion and provide real-time active error compensation by deflecting its tip to compensate physiological tremor and other erroneous movement components.

Vision Guided Cell Micromanipulation

A vision-guided robotic approach is proposed to replace human intervention. A 3 degree-of-freedom piezoelectric-driven robotic manipulator is used to hold a micropipette. A high speed camera with a embedded processor captures images of the cells and the micropipette tip under a conventional microscope, processes the images, and controls the robotic manipulator in real-time to perform the intended task.

OPTICAL MICRO-MOTION TRACKER

Detecting micro motion of a microsurgical instrument in real time to aid training of new surgeons and discover more findings about tremor nature of human's hand. [read more ...]

Rehabilitation Robotics

ACTIVE PATHOLOGICAL TREMOR COMPENSATION USING FUNCTIONAL ELECTRICAL STIMULATIONS

We use the sensed physical motion and EMG signals from the upper limb to attenuate the pathological tremor in real time manner. A filtering algorithm will be developed to differentiate the intended motion and the tremor. [read more ...]

MOTIVATION DRIVEN STROKE REHABILITATION VIA BIO-SIGNAL CONTROL SYSTEM

Restore voluntary motor function by bridging gap in damaged/diseased parts of nervous system. A brain-computer interface senses surface electroencephalogram signals elicited by motor imagery & processes it into semantic signals to control functional electrical stimulation of skeletal muscles.
