Product Overview
TDK RoboKit1 SmartRobotics™ Platform
The TDK Robokit1 combines sensors, processors, and actuators on a single board, making it an ideal robotics platform for quick prototyping and development. RoboKit1 integrates key product offerings such as 6-axis IMU, industrial IMU modules, capacitive barometric pressure sensor, digital I²S microphone, temp sensor, ultrasonic Time of Flight (ToF) sensors, magnetometer, and motor controller on a single PCB.
It also comes equipped with ARM® Cortex®-M7, multiple interfaces, and is compatible with multiple processor platforms such as Raspberry Pi and ASUS Tinker Board. RoboKit1 is not just another dev board—it is the comprehensive TDK solution showcase!
Product Overview
TDK’s SmartPressure™ products
TDK InvenSense’s barometric pressure sensors use an innovative capacitive MEMS architecture to deliver lower power consumption and lower noise than competing technologies. The SmartPressure products can measure height change below 5 cm, less than the height of a single stair step.
With its industry-leading measurement accuracy and ultra-low power operation for always-on applications, the SmartPressure product family is best suited for smart phones, tablets, wearables, drones, and many other devices to determine accurate location of E911 calls, track changes in elevation for activity monitoring, support indoor or 3D navigation, and other motion- or position-based services. Home appliances such as washing machines, vacuum cleaners, water and gas meters can use the pressure sensors to monitor air flow or water level.
The SmartPressure product family includes support for waterproofing to 10 ATM.
A Development Kit is available for each product family for easy evaluation.
Applications & Cases
Application Note
The Metaverse Will Engage All Five Senses
The technology that delivers the metaverse will build on the technology for virtual reality, using more sensors, and more different kinds of sensors. TDK has one of the richest sensor portfolios in the industry, extensive software expertise, and excels at sensor fusion.
Sensors for New Mobility
【How electrification and autonomous driving are expanding the role of sensor technologies within automotive designs】

The automotive production landscape is changing. The proliferation of electronic devices and sensors in modern car design has grown exponentially in recent years. It will expand further as the industry continues its transition toward e-mobility and autonomous driving. The core technologies featured in electric vehicles expand the realm into which sensors are deployed. Also, combustion engine vehicle gas sensors have shifted away from exhaust gas monitoring toward internal air quality (IAQ) measurement.
Application Note
Sensors for Drones
TDK offers a full suite of sensors that are perfectly suited for drones of all types from consumer/prosumer models to industrial units.
 
In just a few years, drones have become indispensable in one application after another, including such diverse areas as agriculture, real estate and cinematography. For all this success, drones still have almost unlimited potential given their suitability for a wide variety of uses including delivery, inspection, search & rescue, monitoring, and mapping, to name just a few.
 
Fundamental to drone utility is sensor technology. Drones rely on diverse sets of sensors for two broad purposes. First for their own functionality, notably flight and navigation, and second, for their ancillary capabilities – cameras for vision, motion detectors to sense activity, heat sensors to detect temperature, and so on.

Sensors solutions that enable advanced control of service robots
Service robots are widely used in various situations such as logistics / transport, security, cleaning, housework, hobbies / entertainment and care / assistance. Since service robots are used in a wide variety of situations, it is necessary to fulfil many requirements such as smooth communication with humans (HMI), ensuring safety and responding to changes in the real time. In service robots, the role of a sensor is very important. In this article, we will take a vacuum cleaner robots as an example.
