Solution

LiDAR solution for assistive-device ranging

Provide forward or downward range input in an assistive device, with TF-Luna as the featured sensor.

Assistive device using TF-Luna for distance sensing

Scenario

Application scenario

The customer allows the university material to be shown as an application direction. The product being sold and recommended is TF-Luna, not a walking cane. Recognition, alerts, and safety policy remain with the assistive-device system.

Engineering problem

Wearable or handheld posture changes the field of view.
Targets with different material and height produce different returns.
Safety prompts require validation with target users and environments.

Why LiDAR

Compact, low-power range input is easy to embed in an assistive device so the upper system can sense nearby targets.

Workflow

Define device position, detection direction, and alert distance.
Validate TF-Luna against mounting space and power constraints.
Connect range and status to the device controller.
Validate prompts indoors and outdoors with different floors and obstacles.

Technology comparison and selection

Dimension	Condition	LiDAR	Alternative	Alternative performance	Conclusion
Near-target sensing	The assistive device needs compact, low-power range input.	Point range and status.	Ultrasonic sensing	Useful at short range but sensitive to angle and material.	Use TF-Luna as the sensor; the device owns alert logic. 公开来源Benewake customer application materials · Verified 2026-09-01

Selection

Product selection guide

Current material supports one explicit candidate. Its fit and boundary are shown directly without inventing an alternative.

Model	Key product facts	Best fit and rationale	Operating boundary	Product details
TF-Luna	Output data Single-point Distance Value Measuring range 0.2 ~ 8 m Interface UART, I/O, I²C Protection Without enclosure	TF-Luna is under 5 g and no more than 0.35 W and can provide short-range single-point input in a controlled direction for a cane or assistive device.	Benewake supplies the sensor, not a complete assistive device; validate alerts, ergonomics, coverage, failure handling and user safety at system level.	View product

Installation and integration

Mount TF-Luna to the device structure with a defined field of view and alert direction; the controller owns filtering, alerts, and fault handling.

Operating limits

Do not present the sensor as a complete walking-cane product; the device maker must validate user safety and assistive effectiveness.
