SERVO

The power support for your wheelchair

The SERVO makes it possible for wheelchair users — even with reduced strength — to move independently and increase their range of action.

 

Easy mobile —

everywhere

The SERVO – powered wheels are disengaged easily and without tools.
Each  foldable wheelchair with attached SERVO may be folded as before. Due to the SERVO’s new wheel mounting system, NUI, the powered wheels are easily stored next to or on top of each other.
The SERVO fits almost into any trunk because it can be stored in a space-saving way. He powered wheels without stud axles are particularly easily stored, also in narrow spaces.

SERVO APP

As individual as you are

The SERVO App connects on its appealing surface the need for individual driving characteristics, fast information, aid in case of need, and, if necessary a direct contact with AAT‘s service center. The operational profi les allow you to choose easily among the great variety of possibilities concerning the levels of power the SERVO offers you.

Advantages that convince

    • Choose among 5 different driving profiles that are sequentially adjustable
    • Roll down control function - adjustable brake deceleration when driving downhill
    • Extensive information in regard to the product and easy contact with the AAT service center or your local dealer if necessary
    • Transfer of the control unit and adjustment of its functions

 







The SERVO App is available for android and iOS devices!




Driving profiles - experience the full power spectrum of the SERVO

The predefined driving profiles are generated in such a way that the most diverse requirements are covered. In addition, each profile can easily be adjusted to your individual needs. With the integrated „roll down control function“ e.g. the brake deceleration on slopes can be adapted to your personal preferences. For special needs or particular disease patterns the profile PERSONAL is available to you. An AAT representative or your local dealer can adjust this profile especially for you. You can easily alternate between the various profiles by simply pressing a key.




Driving profile "Tetra"

A profile particularly adjusted to tetraplegics

To respond to the special features for quadriplegics the SERVO provides the operational profile “Tetra”, which can be selected via the SERVO APP or simply at the control unit. “Tetra” combines a number of predefined parameter such as the reduction of power to move the gripping rings (sensitivity), adjusted acceleration and braking performance, and much more. In addition, these parameter can be individually adjusted to the demands of the user via the SERVO APP.

The unique roll down function brakes the SERVO independently and holds this particular speed. That way the speed does not increase too much when going downhill, which gives the user an additional sense of security.

The speed at which the automatic braking function is activated can also be adjusted individually via the SERVO APP. The uphill program for quadriplegics is made possible by a patented sensor system. The very powerful motors support the user particularly when going uphill. Thus it is made possible to drive uphill safely and efficiently even with little strength in the hands.

The SERVO’s “Tetra package” is completed by optionally available tetra grip gripping rings.

SERVO Driving profile Dynamic Extension
Driving profile "Dynamic Extension"

When Mobility becomes an “Experience”

While accessory drives support a device in general up to 6 km/h, the driving profile Dynamic clearly surpasses this speed. The result is a faster and sporty type of driving, which is also good for longer distances. In addition, the agile and dynamic driving characteristics still remain for slower drives.

Due to the driving profile Dynamic, there is an increased engine output compared to the standard driving profiles, which is used specifically during the support cycle. This is achieved by a highly efficient core programming and the powered system’s full exploitation of capacity.

In addition, this driving profile offers a faster and stronger acceleration because of the start-up behavior’s special programming. The result for the user is a considerably stronger start-up momentum for each deflection of the hand rim.

The coasting, the motor-supported coasting of the wheelchair, is programmed in such a way that the motor can further show its great power because it leads to an increased momentum of the SERVO. As always, the parameter start-up, coasting and support level of the driving program Dynamic can be adjusted individually in the SERVO App. The driving profile Dynamic is available as an option.


Groundbreaking, due to innovative technology —

the SERVO convinces on all counts


 
  • Lithium ion battery with a range up to 55 km
  • NUI – novel mounting and locking system for the powered wheels
  • Powered wheels without stud axles
  • Supports the initial propel-ling movement up to 6 km/h
  • Individual mounting to almost all commercially available wheelchairs
  • Lightweight, compact and manoeuvrable
  • Easily stored and trans-ported, also fits in narrow spaces
  • ALPHA concept, a combination of state-of-the-art electrical drives and lithium ion batteries






ALPHA Konzept

Synergy of power and effortlessness

The ALPHA concept is the new measure of all things concerning state-of-the-art engines in connection with the newly developed battery pack with lithium ion technology. This concept is the reason why the SERVO reaches a range up to 55 km while the battery merely weighs 4.2 kg.



Innovative technology that inspires —

mounting the SERVO

The newly developed mounting and locking system, NUI, does not need stud axles any more, which makes a fast and effortless mounting of the powered wheels to the wheelchair possible. Since the SERVO can be mounted to almost all wheelchairs, you do not need to do without your personal wheelchair you are used to.
