Rolling Resistance: Problem Solving

Rolling Resistance: Problem Solving

Rolling resistance, also known as rolling friction, is the force that resists the motion of a rolling object, such as a wheel, tire, or ball, when it moves over a surface. It is caused by the deformation of the object and the surface in contact with each other, as well as other factors like internal friction, hysteresis, and energy losses within the materials. Rolling resistance opposes the object's motion, requiring additional energy to overcome it and maintain movement. In practical...

Summary

This study presents an eye-safe laser ranging sensor for small unmanned aerial vehicles. The sensor uses structured light for accurate distance measurements up to 30 meters, ideal for covert operations.

Area of Science:

Optoelectronics and Sensor Technology
Robotics and Autonomous Systems

Background:

Small unmanned aerial vehicles (UAVs) require compact and safe sensing solutions.
Existing laser ranging technologies may not meet size, safety, or covertness requirements for certain UAV applications.

Purpose of the Study:

To describe the design and performance of a novel laser ranging sensor.
To demonstrate its suitability for small UAVs and other applications requiring eye-safe, covert distance measurement.

Main Methods:

Utilizes a structured-light technique with a diode emitter array and line-scan charge-coupled devices (CCDs).
Measures ranges up to 30 meters across 64 field angles within a 90-degree field of view.
Designed for eye-safe operation with a laser wavelength invisible to night vision devices.
