Due to its easy and intuitive operation our drive control system BonRoll is suitable for all electric wheelchairs with DC motor (front or rear wheel drive).
Right hand you can see a sample wheelchair equipped with our drive control system. The described drive control has been developed for this concrete wheelchair, but the customization for any other wheelchair can be provided.
A special feature of the BonRoll are the two different operating modes "street" and "home", depending on the wheelchair type. In the "street" mode you can steer the wheelchair using two wheels (like a car). The "home" mode allows directing the wheelchair without pivoted wheels by changing the rotation speed of the powered wheels (like a tank). That way, it is even possible to turn on its own axis by rotating the opposed wheels in different directions. Both modes can also be used at one wheelchair. Furthermore BonRoll offers numerous additional options: Up to six servo motors can be controlled to perform different step less adjustments (i.e. position of the seat, the backrest, the footrest...). Also the lights and the turn signal can be activated in a comfortable way. A special interface permits the use of optional features as an alternative wheelchair steering by sucking and blowing or a remote control for other devices (i.e. TV) using the joystick of the wheelchair. The individual characteristics of the drive control unit and the regulation of the particular servo motors can be adjusted easily with special PC software. These include parameters like the acceleration and braking behavior and the cornering ability. Moreover, multiple servo motors can be linked and used simultaneously, so that the preprogrammed seating position is reached faster. A battery charge indicator informes about the battery level. The three main components of the drive control system BonRoll are the control panel, the joystick unit and the main control unit. Panel and joystick are mechanically connected by an aluminum hinge but can be also installed separatly. The data communication between the system components is carried out via CAN-Bus, as used very often in automobile industry. A permanent reciprocal monitoring of the system components ensures that the breakdown or partial damage of one element leads to an immediate and safe disconnection of the whole drive control.
