The AMP js by Method Mobility is a battery-powered, roll-on/roll-off power assist add-on device designed to provide powered propulsion to manual wheelchairs. It consists of a motorized drive unit with an 8-inch drive wheel, outriggers, anti-tip features, and a joystick control system that attaches to the front of a manual wheelchair, converting it into a powered mobility device. The device is intended to provide enhanced mobility to individuals with disabilities who are capable of operating both manual and powered wheelchairs. It assists users in propelling the wheelchair over various indoor and outdoor surfaces, reducing the physical effort required for propulsion while maintaining maneuverability. Key components include a rechargeable lithium-ion battery, brushless DC motor, joystick controller, quick-release docking mechanism, and safety features such as anti-tip bumpers. The system is detachable, allowing the wheelchair to be used in both manual and powered modes.
An assembly of devices added/retrofitted to a manual wheelchair (occupant or attendant driven) to provide the occupant with an electrical-powered drive mechanism, including the energy source (batteries) to achieve this. The steering, control, and brake systems will typically be included. This retrofitted accessory may alter the wheel configuration of the wheelchair in order to provide the powered propulsion (e.g., from a conventional four-wheeled to a tricycle configuration or additional propulsion wheels at the rear of the wheelchair).
