Accelerometer for mobile robot positioning

Accelerometer for Mobile Robot Positioning

An evaluation of a low-cost, small sized solid state accelerometer is described in this paper. The sensor is intended for positioning of a mobile robot or platform. Acceleration signal outputted by the sensor is doubly integrated with time which yields the traveled distance. Bias offset drift exhibits in the acceleration signal is accumulative and the accuracy of the distance measurement deteri...

Positioning And Motion Control For Mobile Robot

Odometry is the most widely used navigation method for mobile robot positioning. In this paper motion control and positioning for a mobile robot working in a warehouse is presented. Odometry system configuration and wheel encoder used are detailed. The calculations of the distance travelled compared to the actual measured distance show some difference that are due to internal and external cause...

Mobile robot positioning: Sensors and techniques

Exact knowledge of the position of a vehicle is a fundamental problem in mobile robot applications. In search for a solution, researchers and engineers have developed a variety of systems, sensors, and techniques for mobile robot positioning. This paper provides a review of relevant mobile robot positioning technologies. The paper defines seven categories for positioning systems: 1. Odometry; 2...

Mobile Robot Positioning: Sensors and Techniques

A Visual Positioning System for Vehicle or Mobile Robot Navigation

Localization of a vehicle is a key component for driving assistance or autonomous navigation. In this work, we propose a visual positioning system (VPS) for vehicle or mobile robot navigation. Different from general landmark-based or model-based approaches, which rely on some predefined known landmarks or a priori information about the environment, no assumptions on the prior knowledge of the s...
