Ground Mobility Device
About the Project
An international collaborative project was initiated to design and manufacture a
mobility device for people with disabilities who have difficulties walking indoors and
outdoors close to their home.
The two primary participants were the International Centre for the Advancement of
Community Based Rehabilitation (CIDA funded), Canada, and the National Institute of
Design, Ahmedabad, India.
Why a ground mobility device?
A ground mobility device provides an alternative way for a disabled person to move
inside and close to home. Because the seat is close to the ground it eliminates the need
to change the environment to a wheelchair height. This design will help the person to:
- Move from one place to another independently;
- Perform activities at ground height (e.g., eating with the family, sweeping, school
work, child care, cooking, washing dishes);
- Carry items (e.g., a water bucket, children).
Who can use this device?
People who have difficulties walking:
- People with old or new injuries to their legs (e.g., polio, amputations, spinal cord
- People with long or short term difficulties;
- Children, adults, or the aged;
- Women or men.
Where to use this device?
- In communities where activities are performed on or close to the ground;
- Urban or rural areas;
- In the home, school, or at work.
How to use this device?
To use the device on her own the person must be able to:
- Sit up;
- Use both arms/hands.
The person must learn how to:
- Lock/unlock the brake (turn the knob);
- Climb on/off (put lock on first).
- Go forwards / Stop or slow down (hold wheels) / Go backwards
Making the device
- This is a simple design which can be easily changed to fit the person better.
- Locally available materials should be used whenever possible.
- The costs depend upon local circumstances, material and labour costs and number of
