Collision Control and Collision Avoidance Using Ultrasonic Sensor
The paper proposes an intelligent collision avoidance system as a prototype, which avoids vehicle accidents and to provide a greatest security to the user in adverse or bad weather condition. Here, Ultrasonic sensor and IR sensors placed in the car, where IR sensor is used to detect the lane and avoids accident in significant manner. The vehicle state information is obtained using Ultrasonic se...
متن کاملCollision Avoidance for Vessels using a Low-Cost Radar Sensor
Collision avoidance for vessels highly depends on a robust obstacle detection. This is commonly achieved by use of high precision radar sensing. For smaller vessels however, the use of low-cost sensors is typical. The idea of this work is to improve the robustness of collision avoidance by integrating a sensor model together with the collision avoidance algorithm in order to consider the accura...
متن کاملModel Based Predictive Control of Auvs for Station Keeping in a Shallow Water Wave Environment
An important consideration for Autonomous Underwater Vehicles in shallow water is station keeping. Station keeping is the ability of the vehicle to maintain position and orientation with regard to a reference object. In shallow water AUV operations, where large hydrodynamic forces are developed due to waves, knowledge of the sea is critical to allow for the design of a control system that will ...
متن کاملAvoidance Maneuver Planning Incorporating Station-Keeping Constraints and Automatic Relaxation
Space debris is a rising concern for the sustained operation of our satellites. The population in space is continually growing, both gradually with a steady stream of new launches, and in sudden bursts, as evidenced with the recent collision between the Iridium and inactive COSMOS spacecraft. The problem is most severe in densely populated orbit regimes, where satellites face a sustained presen...
متن کاملLow Power Intelligent Sonars for AUV Navigation and Collision Avoidance
Traditional approaches to AUV collision avoidance involve the adaptation of COTS electronic scanning sonars that have been designed for applications where low power is not a consideration. This has an adverse impact on the endurance and performance of the AUV. The navigation and obstacle avoidance processing is typically performed by the vehicle control processor, acting on large volumes of dat...
