Products & Technologies
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.
We provide Automotive MEMS sensors which have reliability testing performed according to AEC–Q100 and provide PPAP and qualification data upon request. These are designed or specifically qualified and tested for the Automotive market with those unique needs in mind. These support the rapid growth of convenience, infotainment, telematics, Advanced Driver Assistance Systems (ADAS), and other technological features for the Automobile.
In industrial applications such as precision agriculture, high precision GNSS modules, construction machinery, robots, and automatic guided vehicles (AGVs), motion sensor data has become critical in enabling automation, improving efficiency, and monitoring conditions. TDK’s SmartIndustrial™ portfolio of 6-axis IMU modules, IIM-46234 and IIM-46230, delivers the precise motion, and inclination measurements that these applications required. These modules offer the ability to take precise measurements in harsh environments with vibration and wide temperature variations.Applications & Cases
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.
【How electrification and autonomous driving are expanding the role of sensor technologies within automotive designs】
TDK offers a full suite of sensors that are perfectly suited for drones of all types from consumer/prosumer models to industrial units. 
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.

TDK Product Features
Inertial measurement unit (IMU) are devices comprising units that integrate an acceleration sensor and a gyroscope and are used to detect the acceleration and angular velocity of objects.
TDK’s IMUs include six-axis to nine-axis units such as a six-axis IMU with a three-axis acceleration sensor and three-axis gyroscope, a seven-axis IMU that adds a barometric pressure sensor, and a nine-axis IMU that also includes a three-axis compass.
TDK’s motion and inertial sensor family includes acceleration sensors, gyro sensors, and inertial measurement units (IMU), which combine the two. The TDK MEMS Sensor Platform, which incorporates advanced MEMS technology*, is expected to create high added value compound sensors and sensor solutions for the IoT and IoE era.
* MEMS (Micro Electro Mechanical Systems) technology: Micromachining technology that employs the three-dimensional precision processing technologies used in the manufacture of semiconductor integrated circuits to simultaneously create multiple sensors, circuits, movable parts, and other components on a silicon wafer.
