Abstract
An advanced manually propelled wheelchair (100) is described. The wheelchair (100) has a chassis (110). In certain examples this may be a single piece design. The wheelchair (100) may further have one or more of a load adjustment mechanism (150) and a power-assist mechanism. The load adjustment mechanism (150) is configured to adjust a position of a set of rear wheels (120) for the wheelchair (100) relative to a loading of the wheelchair (100). Load adjustment may be performed based on a sensed loading. The power-assist mechanism provides a powered torque to a set of front wheels (130) to help a user propel the wheelchair (100) or to stabilise the wheelchair (100) during use. The power-assist mechanism may be provided as a set of modular front wheel units.
