A unique
robotic device has been developed by experts at Florida Atlantic University.
This robot may prove useful in rehabilitating patients suffering from Parkinson's
disease and stroke.
The
inventors of the cable driven robot say that they have designed and built the
device to aid physical therapists and their patients to retain injured muscles.
The new
robotic device has been made from moving parts like motors, cables and spools,
enclosed within an acrylic case with a handle (joystick) that is indirectly
connected to the system through magnetic attraction.
Dr. Oren
Masory, a professor of Mechanical Engineering in the College of Engineering and
Computer Science who developed the cable driven robot with engineering graduate
student student Melissa Morris, claims that it is the first-known cable driven
robot to utilize a barrier between the operator and the moving mechanisms of
the system.
The makers
of the device say that the system does not contain any rigid parts that could
suddenly harm or injure the user, and that the device can be used in a physical
therapy office or at home without supervision.
A safety
button has been embedded in the handle of the device. When it is released
during operation, a signal is sent to the controller that the patient has lost
contact with the handle, and the system immediately shuts down.
The device
can operate in various modes which help it guide patients through a series of
routine exercises.
One mode
enables the patient to begin his/her training by following a pre-programmed
path which corresponds to “repetitions” done in traditional physical therapy,
while another mode assists the patient as he/she attempts to follow the path,
and the robot corrects them if they move outside of the path in much the same
way a therapist would do by providing gentle resistance.
