Abstract
Work-related musculoskeletal disorders (WMSD), especially lower back pain
is reported as one of the main health problems among healthcare workers. The causes
of the problem are mainly healthcare tasks such as manual patient handling and
moving beds. There are several solutions that are already available in the market,
proven to be able to solve the problem. However, there are currently no device in the
market that is equipped with omnidirectional movement capability, which strictly
limits the mobility of the device in cramped space, and also complicating the controls.
In this project, a Mecanum wheel drive system is created and integrated onto a patient
transfer device to allows omnidirectional movement. The completed prototype’s
performance is verified by comparing it with a MATLAB simulation. The result shows
that the prototype is able to move in the same motion as simulated with some deviation.
The largest deviation measured is during leftward movement with deviation of 11.5cm
on the left wheel and 11.8cm on the right wheel. However, even with the deviation,
the prototype successfully completed a patient transfer process.
