Design and development of a portable and adjustable wheelchair ramp

Currently, Singapore is facing an aging population. It is not surprising that there will be a greater surge of elderly using more mobility devices such as wheelchairs. Hence, there is a growing need for facilities to include designs that enable the easy accessibility of these mobility devices. Many...
