Smartphone is your remote control

mycar-2016-07-01-181102_nexus4_angle1_s Smartphone for the modern people is not just communication tool – with Mobilis controller it is a complete remote control system for your wheelchair. Usually simple operations require additional effort or assistance of outside people: for example just to bring wheelchair from distant corner of the room when you are on the sofa. With mobilis you can do this just by using smartphone application! Requirements for smartphone: Bluetooth wireless interface Android 2.3 or above (iOS version in development)

To control the truck while driving on it, standard joystick is used (can be mounted for the left / right hand). The joystick also contains a speed controller and on/off switch. However Mobilis adds even more opportunities to adjust your joystick. Using your smartphone application you can adjust:

  • The dimensions of the central “neutral” zone
  • Sensitivity to the joystick movements
  • Form (function) of wheelchair reaction to joystick movements
  • Limit the maximum speed of the wheelchair
  • Limit startup acceleration
  • Adjust turn sensitivity separately from acceleration
  • Set up a system of tremor compensation (anti-shaking)

 

Detailed indication of battery and wheelchair status

mycar-2016-07-01-181102_nexus4_portrait_top The controller reports to the smartphone telemetry data about wheelchair state, including precise battery voltage. The system displays remain battery charge as a percentage, this allows to accurately plan the trip. The system also monitors current consumed by motors. The controller performs system self-test constantly (checks the status of its electronic circuits) and warns the user about detected potential problems. This allows you to plan wheelchair maintenance.
