For the needs of bedridden people in their daily life, posture
changing and body transferring are two typical healthcare activities.
Hence, designated bed motions should be able to modify
people’s posture by the following tasks: sitting, leg or knee lifting,
bed height changing, body turning, etc. Also, bedridden
people should be occasionally transferred from the main bed to
a nursing bed or a wheelchair. To perform such tasks, a complete
solution with mechatronic control system of related sensors and
actuators and a graphical user interface is a great need for control
engineers and healthcare personnel.
