The IIM-20670 is calibrated over multiple temperature points and available in a compact QFN 4.5 x 4.5 x 1.1mm³ form. The package has wettable flanks that simplify inspection at the end of the assembly line, added TDK. The IMU also features programmable digital filters and a 10MHz SPI where data integrity can be assessed by a CRC-based error-detecting code algorithm. The IIM-20670 contains an accelerometer thermal stability of 45 microg per degree C, an accelerometer bias repeatability of 1mg and a programmable output of 64G alongside a tilt algorithm that outputs pitch and roll data over the full temperature range.

According to TDK, these specifications allow the IIM-20670 to provide one of the most stable six-axis tilt outputs in the industry. It is suitable for applications that need robust, fast, and accurate tilt or stabilisation performance such as 5G platform, industrial tilt modules or industrial / agricultural drones.

The thermal stable IMU is also claimed to have best in class accelerometer bias offset and repeatability with a strong vibration rectification performance.

A comprehensive development and evaluation platform along with necessary software are available to enable quick-to-market development of customer systems

TDK’s IIM-20670 platform is available now for evaluation and available through distribution partners worldwide by end of July 2023.

Fri, Jun 02, 2023

The OP03011 liquid crystal on silicon (LCoS) panel integrates the array and frame buffer into an ultra-compact single-chip solution that is lightweight and low-power for smart glasses

The OP03011 is a single chip, 648p LCoS panel for next generation augmented reality (AR), extended reality (XR) and mixed reality (MR) glasses and head-mounted displays. The LCOS panel features 3.8 micron pixels in what is claimed to be one of the world’s smallest 0.14-inch optical formats. The low power, lightweight design is intended for next-generation glasses that can be worn 24/7, said Omnivision.

The growing interest in AR glasses has led OEMs to design more functionality into slim, fashionable designs that consume very little power and are lightweight, allowing them to be worn for long periods. The OP03011 is designed in a compact format for applications requiring a smaller field of view and lower resolution, making it well suited for some of the sleekest, most innovatively designed AR glasses, said Devang Patel, marketing director for the IoT and emerging segment, Omnivision. “The OP03011 supports applications of next-generation smart glasses, like displaying notifications in the user’s field of view and access to GPS for maps and directions directly from the glasses, so the user never needs to pull out their smartphone,” he said.

The OP03011 features 648 x 648 resolution at 120Hz and comes in a small FPCA package. It supports a single-lane MIPI-DSI interface.

Samples are available now, and the OP03011 will be in mass production in Q4 of 2023.

Six-axis force-torque sensors has haptic feedback for micro robotics

Thu, May 25, 2023

A miniature, six-axis force-torque sensor unveiled by Bota Systems is the company’s smallest yet. The MiniONE is designed to enhance micro-robotic systems with haptic feedback. It is simple to install between a robot arm and almost any end of arm tooling (EOAT), said the company.

It weighs just 30g and has some dimensions of 30mm and a depth of 22.2mm, making it suitable for medical applications, product testing, as well as precision tasks like micro-assembly and micro-polishing. It is also suitable for use as a fingertip sensor in hands and grippers and in humanoid robots.

The MiniONE sensor provides a low noise signal with high sensitivity, said Bota Systems, together with drift performance and a design that includes temperature sensors and built-in filters, making it easy to program and set up.

Unlike competing products which need adapters or interface boxes, the MiniONE requires no external hardware, making it simpler to use, pointed out Bota Systems. By fully integrating the MiniONE’s electronics in its shielded housing, wiring, weight, complexity and measurement uncertainty are all reduced.

The MiniONE is dust- and water-resistant to IP67 and includes a USB communications interface. To save development time, it is available with Bota Systems’ software packages for ROS (Robot operating system), Matlab, Labview, TwinCAT and Python.

Klajd Lika, CEO and co- founder at Bota Systems, commented: “By giving robots the sense of touch, our sensors enable them to move as naturally and freely as people.”

A robotic force torque sensor measures force and torque when they are applied on its surface. By using the measured signals in real-time feedback control, robots can perform challenging interaction tasks. A six-axis sensor measures forces and torques on three axes each.

Robots are increasingly being used in more unstructured environments and are required to perform more demanding tasks and to collaborate with people, necessitating sensors to make them aware of their surroundings, explained Bota Systems. Force torque sensors enable them to perform previously impossible tasks, such as polishing on complex surfaces, robotic surgery, assembling delicate parts with tight tolerance, or carrying out interactive tasks in open environments.

The MiniONE six-axis force-torque sensor is compatible with a wide range of robot brands, such as Mecademic Robotics, Nachi Robotic Systems, Rokae and Yaskawa, as well as and gripper and hands from Robotiq, Shadow Robot and Schunk.

Bota Systems will be showing the MiniONE at ICRA, the IEEE International Conference on Robotics and Automation, from 29 May – 2 June 2023, in London, UK (booth I19).
