‘Attitude Measurement Sensor myAHRS+’

myAHRS+ can measure the attitude of robot or drone (roll, pitch, yaw) in three dimensional space by using triple axis acceleration sensor, tripe axis gyroscope sensor, and magnetometer sensor and integrating output of each sensor. The myAHRS+ sensor has been mounted with an algorithm that can integrate measured values out of each sensor in a small size ARM processor. It has been integrated to a small size board with 21mm L x 27mm W. The sensor has a merit to be used for easy connection to PC by supporting USB and i2c interface.

When this sensor is mounted on a humanoid robot, it is available to understand the attitude and position of robot in three dimensional space. It can be installed not only in robot but also in vehicle or drone and utilized for a precision measurement of position. The sensor not only supplies a driver for the open source type ROS (Robot Operating System) but also provides a technical support. It seems that the sensor shall be beneficial to companies or developers who develop programs utilizing ROS. WITHROBOT Co., Ltd has revealed its excellent performance compared to the prices of competitive companies of ‘Razor IMU' and 'XSence MTi30-AHRS’. The company has developed a sensor data filter and an integrated algorithm with its own technical skill.

WITHROBOT Co., Ltd has started a full-scale overseas exportation since October last year, and current overseas sales gets ahead of domestic sales. During the next year, the company plans to release the product that will be added with a motion recognition function.

‘USB 3.0 Board Type Camera oCam’

WITHROBOT Co., Ltd has released a USB 3.0 board type camera, 'oCam' along with myAHRS+. It is a product that has been developed to fit to a drone or a small size humanoid. While a robotic vision system for industrial robots emphasizes the performance rather than the price, size, and consumed electric power of camera, size and consumed electric power and price are important along with its performance for a drone or a small size humanoid that has been recently emerged. 'oCAM' is the camera for a vision system that has been developed for such market demand. As 'oCAM' supports the USB 3.0 interface, data transmission rate becomes better to reduce a burden on CPU. Accordingly, CPU source can be used for a highly advanced image processing rather than its own image transmission.

To minimize the size of product, CMOS image sensor and additional circuit have not exceeded 4cm of each length and width. Without a separate power supply device, the camera can be operated only with the power of USB bus. It can be also used in LINUX and a small size embedded board as well as Window PC as it supports UVC(USB Video Class). It is expected to be adopted actively for the object trace or the image recognition of robot. WITHROBOT Co., Ltd has revealed that the camera has a high price competitiveness compared to the products of competitors, ‘See3CAMCU50' and 'DFM24UP031-ML’. and a flexibility for easy application to various applied fields. WITHROBOT Co. Ltd has developed its own firmware and software for a hardware camera control from image sensor to communication. Its supplying price is 99 dollars.

Through videos and professional media (English magazine), WITHROBOT Co., Ltd plans to provide various examples that can be applied to robots. Along with this, the company plans to release a camera model additionally that has adopted more various sensors.
