slide 1: Title and Authors


IndependenceTM 3000

slide 2: Configuration of the two sets of drive wheels and casters

Slide text:

  • Electronic Balance System (EBS) responds to changes in Center of Gravity (CoG)
  • Two sets of drive wheels form a cluster
  • 4 Mode Functions: Standard, Remote, 4-Wheel, Balance

Graphic description:

This picture illustrates the configuration of the two sets of drive wheels and casters in standard function.


IndependenceTM 3000 Standard

slide 3: Picture of IBOT

Slide text:

  • Similar to a standard power wheelchair (with EBS off)
  • Used for indoor and outdoor settings that have reasonably level surfaces

Graphic description:

This picture demonstrates the IBOT in standard function maneuvering in a bathroom.


IndependenceTM 3000 Remote

slide 4: IBOT traversing up a ramp into a van

Slide text:

  • Assists in loading the device for transport
  • Assists in positioning the device for transfers

Graphic description:

This pictures demonstrates the IBOT traversing up a ramp into a van via remote function by a person (not the user) standing outside of the van.

slide 5: IBOT being used outdoors

Slide text:

  • Enables a person to negotiate obstacles and uneven terrain
  • Primarily for outdoor use

Graphic description:

This picture shows the IBOT being used outdoors in grass and gravel.


IndependenceTM 3000 Balance

slide 6: Pictures demonstrates balance function

Slide text:

  • Enables a person to reach for high objects
  • Enables a person to be at eye level with someone standing or walking

Graphic description:

This pictures demonstrates balance function in which the drive wheels rotate to elevate the chair allowing the user to reach items on an upper shelf.


The Research Question

slide 7: The Research Question

Slide text:

Is the IndependenceTM 3000 IBOTTM Transporter an effective mobility device at home and in the community with experienced wheelchair users?


IndependenceTM 3000 Method

slide 8: IndependenceTM 3000 Methods

Slide text:

  • 4 “expert” wheelchair users used the device within their home, work, and community environments for 1 week
  • Reports from each participant
  • Data recorded from a computerized data logger

IndependenceTM 3000 Results

slide 9: IndependenceTM 3000 Results

Slide text:

  • Subjects used all functions. Four-wheel function was reported to be most useful
  • Balance function was more desirable than initially anticipated

Graphic description:

Again, this picture demonstrates balance function with the user conversing with a colleague eye-to-eye.


IndependenceTM 3000 Results

slide10: IndependenceTM 3000 Results

Graphic description:

This table reports the results of data collection for all functions grouped as total data for all functions and then individual scores for standard mode, 4-wheel drive mode and balance mode. The data is separated by weekdays and weekends.


IndependenceTM 3000 Results

slide11: IndependenceTM 3000 Results

Graphic description:

This table contains summary data for the 4 expert wheelchair users for a period of 1 week. The table combined results for weekdays and weekends grouped as total data for all functions and also as individual scores for standard mode, 4-wheel drive mode and balance mode.

In all functions, users traveled a mean of 3.2 km/day, sd=1.4km, traveled a mean of 77.4 km in total distance, used the chair a mean of 6.8 hrs/day, sd=2.4 hrs, and used the chair of 163.9 hours.


IndependenceTM 3000 Results

Slide 12: use in a brick patio and gravel driveway

Slide text:

Distance traveled was comparable to that reported by Cooper et al. (2001) for PWC-users.

Graphic description:

These images show the Independence 3000 in use in a variety of outdoor settings--a brick patio and a gravel driveway.


IndependenceTM 3000 Significance

slide13: driving on a gravel driveway

Slide text:

The IBOT has the Potential to provide greater functional ability by allowing wheelchair users access to areas and activities that are currently inaccessible.
