SensorCloud is a unique sensor data storage, visualization, and remote management platform that leverages powerful Cloud computing technologies to provide excellent data scalability, rapid visualization, and user programmable analysis.

MicroStrain sensors can instantly upload their data to SensorCloud via an ethernet-connected WSDA-2000. Once uploaded, your data is securely stored in the Cloud and can be accessed from anywhere, or downloaded for offline use.

Configurable alerts can be set to help notify you of real-time event in your data.

MathEngine allows you to perform analytics on your data, all in the Cloud. Pre-built functions are available for ease of use, while IPython Notebooks allow advanced users to write custom scripts to be run on their data once, or on a schedule.

The MicroStrain Communication Library (MSCL) is our open-sourced API that simplifies writing code to interact with our sensors. MIP SDK is a lightweight C/C++ library for interacting with MicroStrain G and C-series products via baremetal and resource constrained microcontrollers.

Both APIs are readily available and fully-documented on GitHub, featuring valuable tools such as full documentation, example code, and a quick start guide.

Built for ROS

Robot Operating System (ROS) is an open-source, meta-operating system for your robot. It provides the services you would expect from an operating system, including hardware abstraction, low-level device control, implementation of commonly-used functionality, message-passing between processes, and package management. ROS can be used in building and simulating robotics applications, as well as unmanned ground vehicles and simultaneous localization and mapping (SLAM). MicroStrain has an open source License free (MIT License) series of drivers specifically designed and tested for ROS.

Estabilização da plataforma

Sim, o 3DM-GV7-AHRS está pronto para ROS com drivers ROS dedicados disponíveis. A MicroStrain da HBK fornece drivers ROS atualizados que garantem o cumprimento das normas e capacidades de integração reforçadas para aplicações robóticas.

O Filtro de Kalman Estendido Auto-Adaptativo é um algoritmo avançado de fusão de sensores que se ajusta automaticamente às condições e dinâmicas ambientais em mudança. Isto garante medições consistentemente fiáveis mesmo em ambientes desafiantes com elevada aceleração, vibração ou interferência.

Cada unidade 3DM-GV7-AHRS é calibrada individualmente de fábrica para um desempenho ótimo em amplas gamas de temperatura de funcionamento. O sensor também possui capacidades de teste contínuas incorporadas e compensação total de temperatura para manter a precisão ao longo de toda a sua vida útil.

Sim, o 3DM-GV7-AHRS permite a configuração independente das saídas brutas da IMU (aceleração e taxa angular) e das saídas filtradas do AHRS (estimativas de atitude e rumo), proporcionando flexibilidade para diferentes requisitos de aplicação.

Sim, o 3DM-GV7-AHRS e todos os produtos MicroStrain da HBK cumprem a NDAA. Isto significa que são adequados para uso em:

EUA. Contratos do Departamento de Defesa
Aquisições de agências governamentais
Programas de contratantes de defesa
Aplicações de infraestruturas críticas
