This paper presents mechanism and control of a four-wheel-drive (4WD) robotic platform for wheelchairs. The 4WD mechanism equips four wheels, two omni-wheels in front and two normal tires in rear. The normal wheel and the omni-wheel, mounted on the same side of the base, are interconnected by a synchro-drive transmission to rotate in unison with a drive motor. To control chair orientation on the 4WD...
This paper presents a development of a 4WD omnidirectional wheelchair with a chair tilting system for climbing single high step. For enhancing the step climb capability of standard wheelchairs, a Four-wheel-drive(4WD) mechanism is introduced. The mobile platform equips four wheels. A pair of front-rear wheels which mounted on the same side of the mechanism, are interconnected by belt transmissions...
This paper presents the development of 4WD omnidirectional wheelchair with a chair tilting mechanism and experimental verification using a wheelchair prototype. For enhancing the mobility of standard wheelchairs, a new type of omnidirectional mobile platform with four-wheel drive (4WD) mechanism is introduced. The mobile platform includes a pair of normal wheels on the rear side of the platform and...
In this paper, a new type of omnidirectional mobile platform with four-wheel drive (4WD) mechanism is presented. The mobile platform includes a pair of normal wheels on the rear side of the platform and a pair of omni-wheels on the front side. The normal wheel in rear and the omni-wheel in front, mounted on the same side of the platform, are interconnected by a chain or a belt transmission to rotate...
