Priced for consumer market, IMU is accurate and efficient, says Bosch

Mon, Oct 24, 2022

Priced for cost-sensitive consumer applications, the cost-effective BMI323 motion sensor inertial measurement unit (IMU) has been announced by Bosch Sensortec. It is designed with integrated features for a shorter development time.

The BMI323 is suitable for standard consumer products, such as toys, gaming controllers, remote controls, wearables, fitness trackers, smart watches, tablets and laptops.

The general-purpose, low power IMU combines acceleration and angular rate (gyroscopic) measurement with intelligent features that are triggered by motion. These make development faster and easier for OEMs, claimed Bosch Sensortec. For example, the BMI323 already includes Bosch Sensortec’s step counter software, so customers do not need to spend time developing their own algorithms. Other features include motion detection that can turn sub-systems on or off when a device, such as a TV remote control, is put down or picked up, to reduce overall power consumption.

Bosch Sensortec has improved accelerometer performance compared to the earlier BMI160 IMU and has also lowered power consumption. In high-performance mode, using both the gyroscope and the accelerometer, the BMI323 has a current consumption of 790 microA compared to 925 microA on the BMI160. This represents a reduction of nearly 15 per cent.

The six-axis BMI323 has a self-calibrating 16-bit triaxial gyroscope, a 16-bit triaxial accelerometer, and a 16-bit digital temperature sensor housed in a miniature 2.5 x 3.0 x 0.83mm³ (14-pin) LGA package. This is pin to pin compatible with the BMI160.

The BMI323 is the first IMU device announced by Bosch Sensortec to include the new I3C interface, in addition to the SPI and I2C interfaces.

The IMU is available now.

Infineon’s SaaS supports IoT developers improve offering

Fri, Oct 21, 2022

The next-generation SaaS (software as a service) release of Infineon’s Cirrent IoT Network Intelligence (INI) helps developers quickly and cost-effectively gather information about their products to increase reliability, improve product performance, and reduce support cost, claimed the company.

It can be used by product and development teams to identify, monitor and solve customer and product problems. Its Cirrent Agent embedded software can be deployed in new products or rolled out over-the-air to existing fleets for devices to report data into the Cirrent Cloud. Development teams can use the online console with new artificial intelligence and machine learning capabilities to analyse product data and get new insights into product performance in the field.

“Too many IoT product companies lack both the data and tools to look at the data,” said Rob Conant, vice president of software and ecosystem, Infineon. The Cirrent INI gives developers the ability to quickly gather data on products in the field with dashboards and tools that provide actionable insights to solve problems and help drive strategic product development, he said. He added that this is “just one example of Infineon’s digitalisation efforts to help our customers make better products”.

The Cirrent INI includes the Cirrent Agent embedded software, cloud data storage and analysis. It also includes an online web-based console to deliver data-driven product development to improve user experience, decrease returns and increase sales, said the company.

The INI service processes more than a billion data points per day and recently introduced new artificial intelligence and machine learning to accelerate data analysis and meaningful insights for problem verification and resolution.

Cirrent INI is pre-integrated with Infineon’s Airoc Wi-Fi chips, the Airoc Cloud Connectivity Manager and Cirrent Cloud ID. Modus Toolbox developers can integrate the Cirrent Agent embedded software with pre-integrated libraries and sample applications. Cirrent INI is delivered with 25 built-in events and attributes, extendable to custom events, attributes and measurements specifically tuned for the customer’s applications or environments.

Infineon’s Cirrent INI can be deployed on products using Wi-Fi, Ethernet or cellular connectivity and is available now.

Smart STM32 wireless module increases productivity says ST

Fri, Oct 21, 2022

The STM32WB5MMGH6 wireless module by STMicroelectronics provides a subsystem for wireless communications for industrial applications using Bluetooth Low Energy, Zigbee and Thread standard and comes with free-to-use protocol stacks. Alternatively, developers can use other proprietary protocols.

At the heart of the module is STMicroelectronics’ STM32WB55 MCU which has an Arm Cortex-M4 core for application-level processing and a Cortex-M0+ dedicated to managing the integrated radio, which safeguards real-time performance in both domains, explained ST.

The MCU’s on-chip RAM is advantageous when running the Thread protocol, added the company.

The module can be used in wireless communication and control of devices such as remote sensors, smart door locks, PC accessories including printers, and infrastructure equipment like network gateways and smart building controllers.

The module integrates the antenna and its matching circuitry, together with all the required passives and timing crystals. Pre-certifications for EMC, Bluetooth LE 5.3, Zigbee 3.0 and OpenThread simplify the mandatory testing and product-level approval processes for users, claimed ST, which saves development costs and accelerates time to market.

The STM32WB5MMGH6 module can be integrated into continuous monitoring systems to enhance the maintenance of industrial equipment and avoid unexpected failures and downtime. It has been used by prescriptive and predictive maintenance company, I-care, with its Wi-care sensors in a wireless and continuous asset monitoring system. When combined with I-see, the company’s cloud-based and AI-driven analytical platform, it provides a complete maintenance industry 4.0 solution, allowing users to visualise equipment status and plan maintenance schedules, said I-care.

“Choosing a wireless module instead of engineering a chip-down solution is the fastest way for developers to complete their projects,” said Hakim Jaafar, general manager – BLE/802.15.4 MCU, STMicroelectronics.

The STM32WB5MMGH6 module is in production now and supported by ST’s 10-year product longevity commitment, which ensures long-term availability of parts for industrial applications.

Product designers working with the STM32WB5MMGH6 module can use the STM32 microcontroller development ecosystem that includes free tools, for example the STM32CubeMX configurator and software, such as the STM32CubeWB MCU package. This package provides essential embedded-development resources, including production-ready MISRA C and ISO/TS 16949-compliant hardware abstraction layer (HAL) and low-layer APIs, FatFS file system, FreeRTOS, communication-protocol stacks, and code examples.

Nvidia ROS release prepares for autonomous mobile robots

Thu, Oct 20, 2022

The latest Isaac ROS software release has been announced at ROSCon and includes new cloud / edge to robot task management and monitoring software for autonomous mobile robot (AMR) fleets.

The software consists of individual packages (GEMs) and complete pipelines (NITROS) for hardware accelerated performance.

It also adds Mission Dispatch and Client functionality. This is an open-source CPU package to assign and monitor tasks from a fleet management system to the robot. It integrates a cloud native micro service which can be integrated as part of larger fleet management systems, explained Nvidia.

Dispatch and Client communicate uses VDA5050, an open standard for communications designed specifically for robot fleets with messages transmitted wirelessly over the IoT protocol MQTT.

Mission Dispatch is a containerised micro-service available for download from NGC, or as source code on Isaac GitHub, and can be integrated into fleet management systems.

Mission Dispatch has been verified to interoperate with other open source ROS 2 clients, including the VDA5050 connector developed by OTTO Motors and InOrbit AI.

Mission Client is compatible with ROS 2 Humble and available as a package in Isaac

ROS GitHub and pre-integrated with the Nav2 navigation stack to assign and track

navigation and other tasks on the robot.

“As mobile robot deployment in the real world accelerates, interoperability is becoming increasingly critical,” commented Ryan Gariepy, CTO at OTTO Motors. “Bridging VDA5050 with ROS2 as an open-source community will promote innovation in fleet management solutions while allowing robot makers to focus on differentiation.”

There is also FreeSpace segmentation, a hardware accelerated package for producing a vision AI based occupancy grid in the proximity of the robot to be used as an input to the navigation stack.

Video data collection for training AI perception models uses new GEMs on the Nvidia Jetson AGX Orin platform measured at two 1080p stereo cameras at 30frames per second (more than 120frames per second total) to reduce the data footprint by a factor of 10x in the H.264 video encode and decode packages for compressed video data recording and playback.
