Essay On Powered Exoskeletons

Orthotics is the branch of medicine that deals with the provision and use of artificial devices such as splints and braces. Several orthotic devices use robotic technology and quite often take the form of a powered exoskeleton. A powered exoskeleton comprises of an outer frame that is worn by an individual and is powered by a system of hydraulics and motors at enhances the power potential of its operator’s limbs. For example, Rex by Rex Bionics is a hands-free, independently controlled robotic exoskeleton that enables paraplegics to stand and walk [13]. Powered exoskeletons are being rigorously researched by scientists for military purposes. This research will in turn help in the development of exoskeletons for medical intent, but a major obstacle in the success of powered exoskeletons is their need for enormous amounts of energy to function. Unless there is a technological breakthrough in portable energy, exoskeletons will not reach their full potential.

D. Robot-Assisted Rehabilitation Therapy

Robotic rehabilitation therapy can be a valuable tool for the recovery of patients who have suffered from a stroke or brain injury. Certain therapeutic robots can also help with Alzheimer, Autism and even Cancer. Robotic assisted rehabilitation therapy has the potential to enhance traditional techniques by improving precision and consistency, especially in therapies that involve repetitive movement. Moreover, therapeutic robots have the ability to record data that can be used to statistically measure a patient’s recovery and keep a track on their progress. This will enable therapists to optimize their treatment techniques according to the patient’s specific needs. Furthermore, robot assisted therapy does not need supervision which reduce...

...ases strain and likelihood of error which results in an increase in the time taken to perform the procedure. Computer assisted surgery uses computers for guiding and performing surgical intrusions in addition to pre-surgical planning. Robotic surgery or robotically assisted surgery overcomes the limitations of traditional Human-Machine Interfaces and enhance the abilities of surgeons during open surgeries. Moreover, there are numerous training simulators available to surgeons for practice and learning purposes.

A. Human-Machine Interfaces in Surgery

A typical surgery involves three entities: the surgeon, the patient and the medium for the surgeon to perform the surgery. The medium allows the surgeon to see and interact with the patient. It may include surgical instruments, camera systems, medical imaging systems or other technologies. In a conventional open surgery
