This same behavior impacts LUCI’s ability to see speed bumps, parking blocks, and other ground objects in front of the chair. If, as shown in the image below, illustrated with the seating assembly in a low position, the Scout is in line with an obstacle and the radar can detect it, then LUCI will slow the chair.
SPEED BUMP PARKING BLOCK
However, as the seat height is raised, the Scout is also elevated off the ground, LUCI’s ability to see low objects decreases accordingly.

LUCI’s collision avoidance coverage is part of a driver assistance system. It is important to keep in mind several things when using LUCI:
• LUCI is not a replacement for wheelchair skills training.
• A power chair, like all motorized vehicles should be operated with an awareness of the dangers in the environments of use.
• LUCI’s sensors are not only the only ones in the industry, they are best-in-class in any industry; but just like all the sensors on cars, trains, and airplanes, that doesn’t mean that they can see everything.
• Sloped ground and high speeds cause momentum that can prevent LUCI from coming to a complete stop before colliding with a detected object. Once LUCI detects anything, however, the driver will be ‘assisted’ in a response, by the slowing of the chair by LUCI.
• LUCI does not apply emergency braking, to prevent tipping the chair and/or throwing the occupant in an avoidance maneuver.
