Collision Avoidance
LUCI uses multiple types of sensors to identify and cross-check potential obstacles. The data from these sources is fused and analyzed to ensure the safety of the surroundings. LUCI obstacle detection has the following capabilities.
MINIMUM
DETECTION RANGE
Objects closer than 3 cm (1.2 in) to the wheelchair may not be registered accurately
Measured from the edge of the wheelchair
MAXIMUM
DETECTION RANGE
Forward: up to 3.5 m (11.5 ft) Backward: up to 1 m (3.3 ft) Sides: up to 2 m (6.6 ft)
Measured from the edge of the wheelchair
MINIMUM OBJECT
DETECTION
Hard objects: 3 cm (1.2 in) Soft objects: 6 cm (2.4 in)
Measured as the cross section of the object facing the wheelchair
LIMITATIONS
Fast moving objects traveling across your path or directly at you may not be detected in time to be avoided. Objects smaller than the above minimums, such as cables, may not be detected by LUCI.
Looking at LUCI’s collision avoidance coverage from the side: LUCI can see more than 10 feet in front and 3 feet in back. To avoid limiting the capability of the wheelchair, LUCI allows the chair to climb over small steps and door thresholds.
LUCI SEES 3 FT BACK LUCI SEES 10 FT FORWARD
LUCI’s collision avoidance intentionally does not limit the chair navigation for obstacles above the power base of the chair. This allows LUCI to still pull into open spaces like tables or desks. However, if you want LUCI to stop your chair at the same spot under a table every time then you can place an object under the table (like a box).
