Exoskeletons for Seniors

As we noted in a previous post, current exoskeletons are problematic because they require the use of crutches for balance. Their target customer appears to be a young-to-middle-aged person who lost lower limb function through an athletic or war-related injury.

imagesBy contrast, the European Union’s Ambient Assisted Living Program has funded research on exoskeletons specifically designed for seniors. Their criteria for successful development of “Exo-legs,” include:

  • Specialised “hands-free” locomotion support/assistance to allow elderly persons to perform their normal, wide-ranging daily activities in an independent manner.
  • Indoor mobility: moving freely within confined spaces giving considerable added value over wheelchairs, be able to perform stand-sit/sit-stand manoeuvres, climb/descend stairs, step over objects, quiet standing, straight walking, turning for centimetric/metric mobility
  • Outdoor mobility: walking/turning on uneven/unstructured surfaces/soft ground, avoiding traffic, crossing roads, taking public transport (buses, trains) to go to rural/distant places, opening/closing doors, using escalators for hectometric/kilometric mobility
  • Cognitive support: provide information/advice to allow decision making when the elderly person has become lost or confused

The project is due to conclude in 2015.
