Application of Multi-sensor Data Fusion Technology in Wheelbarrow Obstacle Avoidance System

Small Obstacle Avoidance Sensor

This paper describes a laser ranging sensor that is suitable for applications like small unmanned aerial vehicles. The hardware consists of a diode emitter array and line-scan charge coupled devices. A structured-light technique measures ranges up to 30 meters for 64 field angles in a 90 degree field of view. Operation is eye safe, and the laser wavelength is not visible to night vision goggles...

Obstacle Avoidance Wheelchair System

We present a collision avoidance system for powered wheelchairs used by people with cognitive disabilities. Such systems increase mobility and feelings of independence, thereby enabling reversal of some symptoms of depression and cognitive impairment and improvement of quality of life. We use a novel 3D sensor developed by Canesta Inc. that allows the wheelchair to “see” obstacles, avoid collis...

Neural Network Based Obstacle Avoidance Using Simulated Sensor Data

This study characterized the design and implementation of a low-cost autonomous robot capable of performing obstacle avoidance using neural networks trained with simulated sensor data. The only sensor used for detecting the environment was an infrared distance sensor attached to a hobby servo, allowing for 180° of sensor visibility. In order to train the neural networks, simulated sensor data w...

Multi-sensor Data Fusion for Future Telematics Application

In this paper, we present multi-sensor data fusion for telematics application. Successful telematics can be realized through the integration of navigation and spatial information. The well-determined acquisition of vehicle’s position plays a vital role in application service. The development of GPS is used to provide the navigation data, but the performance is limited in areas where poor satell...
