EFFECTIVENESS OF OCCUPATIONAL THERAPY USING ROBOT MANIPULATOR FOR ELDERLY

Abstract

Physical activity is one part of occupational therapy, especially in the activity of the knee
joint, where the knee joint is an important part of the movement of the human body. The
movement of the knee joint gets weaker as people age, this is experienced by the elderly. Elderly
are elderly people who often experience knee joints, in addition to the age factor of the knee
joint, it is also influenced by post-accidents, strokes and so on which results in weak knee joint
function. To restore and function the knee joint, a tool that controls the function of the knee joint
is needed, namely a robot manipulator. This robot is a tool that works automatically the same as
the function of the leg which can move the knee joint without any effort from human power but
can be controlled via an Android-based smartphone. This robot manipulator tool works and
functions with instructions via Android in the form of button control facilities that are on
Android and also uses voice commands to control the robot. This manipulator robot consists of
several main supporting components, namely the controller, manipulator, power supply unit,
sensor and actutor. This Robot Manipulator provides a speed setting mode on the tool, so that the
user can adjust the speed of the tool according to its capacity. Also, the movement of this tool
can provide convenience and reduce the risk of weak knee joints. Testing and implementing
robot manipulators for the elderly certainly needs to be analyzed for their achievements by
analyzing using the Wilcoxon Rank test, where this test applies the pretest, namely the initial
safeguards before the use of robots and posttest, namely the action after using the manipulator
robot.
