A motion-based push activation power assist system for manual wheelchairs. The system uses motion-based measurements to determine when the user applies a push to the wheelchair handrims and brakes with the handrims. The push recognition activates a drive system that provides an assistive driving force-pulse to the wheelchair to reduce the demand on the user during propulsion. The brake recognition deactivates the power assist. The provided power assist is proportional to the sensed push and can be modulated to different proportional settings.

The presently disclosure describes a motion assistance system for a wheelchair, for example, a powered drive wheel system that can continually drive a wheelchair in a circular or elliptical path. The motion assistance system comprises a mounting mechanism attachable to one or more structural elements of the wheelchair, and a drive linkage pivotable with respect to the mounting mechanism. A drive wheel can be mounted to an end of the drive linkage such that the drive wheel contacts the ground when installed on the wheelchair. The drive wheel comprises a plurality of lateral rollers positioned radially about the circumference of the power drive wheel. The lateral rollers can rotate about an axis tangential to the circumference of the drive wheel in order to facilitate driving the wheelchair in a radial direction.

The presently disclosure describes a system for a providing an assistive driving force to a wheelchair. The system comprises a power assist system which includes a motion sensing system that is configured to detect the motion of the power assist system, and hence of the wheelchair, and a power assist drive system that is configured to provide an assistive drive force. The system also comprises a sensor, such as may be embedded in a wearable wristband, that is configured to detect the motion of a user's hand and that is in communication with the power assist system. The system may be configured to determine whether the wheelchair is being manually pushed based at least in part on the user motion, and to activate an assistive drive force in response to a manual push. The system may also be configured to determine whether the wheelchair is being manually braked based at least in part on the user motion, and to deactivate an assistive drive force in response to a manual brake.
