The UPnRIDE™ stand-up power wheelchair is intended for medical purposes to provide mobility to persons restricted to a sitting position. The product changes position from Sitting to Standing and Standing to Sitting but also any position in between. The product provides indoor and outdoor mobility.

The UPnRIDE™ device enables disabled and elderly individuals to be mobile in a sitting or standing position indoors and outdoors. The device design is based on the following principles: 1. Using motorized jointed braces and harnessing to safely support the user while sitting, shifting to standing, standing and returning to sitting - 2. Center of gravity (COG) is maintained substantially at the center of the device in all positions, thus maximizing stability and safety. - 3. Balancing the platform which supports the user so that the user always remains vertical even on skewed surfaces. - 4. Implementing an operation and safety algorithms to minimize risks and hazards to the user, even beyond the provisions of standard wheelchairs. The product is comprised of the following modules: - Driving module: a motorized driving chassis that 1. includes two front motorized wheels, two high capacity Li-Ion batteries 21.6VDC / 29.7Ah and a steel frame which is installed as a chassis for the device's components. - Inertial Measurement Unit ("IMU") for measuring 2. ground slopes (pitch and roll) and user's tilt angles (pitch and roll). - Standing and sitting module: a motor-based lifting 3. mechanism for shifting between standing and sitting positions. - 4. Balancing module: a platform that balances the user while sitting or standing, relative to earth. - 5. User interface module: a unit through which the user controls the UPnRIDE™. This module has an "R-NET" controller that contains a Joystick, commanding buttons and a display for viewing indications and status and a switching box for controlling the various modes of operation. - Actuator drivers: five units that control the lifting 6. motors. - 7. Main Controller: a unit which reads all sensors and user inputs, performs the balancing and safety algorithms, and controls all the chairs function.
