Groovex, a consumer robot, has released lovot, an affective Partner Robot. Acceoners PCR radar sensor is used to detect obstacles to prevent lovot from hitting other objects and people as it moves around. Yukai, a Japanese communication robot company, uses millimeter wave radar to detect people near equipment and trigger various actions in boccoemo. If someone simply passes by the robot, it may look up or call them; if someone is standing in front of the robot, it may listen actively or respond happily. In the future, Yukai will consider using sensors for other purposes based on customer needs. For example, monitoring vital signs (breathing and heartbeat) to observe the patients in the hospital; making gesture recognition switch to control the robot in a non-contact way, replacing the traditional buttons, and so on.
Through the above two cases, we find that traditional automotive electronics and cutting-edge consumer electronics have been gradually infiltrated by millimeter wave radar. Automobile Millimeter wave radar has evolved from the early component separation scheme, which is commonly known as the first generation radar scheme, to the second generation millimeter wave radar adopting MMIC + antenna technology, and the current third generation millimeter wave radar scheme, MMIC and MMIC are used to package the antenna.
In a short period of more than ten years, great changes have taken place in the shape of millimeter wave radar. Volume has evolved from the size of a brick to the size of a shell. At the same time, the power consumption is also greatly reduced. It makes it possible for millimeter wave radar to expand to consumer electronics and Internet of things.
As we all know, ultrasonic radar, lidar and millimeter wave radar are three kinds of technologies that are often used for comparison. As shown in the figure below, millimeter wave radar is a technology with obvious advantages. What restricts its development is the cost. Chip and consumer electronics will break this barrier, and the cost will gradually approach the traditional ultrasonic, infrared and laser TOF, But the strong robustness, beautiful and generous designability make its industry use more diversified and rich. I believe that in the near future, there will be more and more millimeter wave radars in our lives, which will bring convenience and intelligence to our lives.
