a novel 3D-imaging sensor based on MIMO radar technology.
RadRob 3D-Imaging Sensors: Key Factors
- Exact detection of position and movement of persons (position better than 5 mm, max. speed 5 m/s, latency time less than 1 ms)
- Position determination of “smart objects” (accuracy better than 5 mm without time offset)
- Resolution: < 1 mm Field of view: 360° horizontal, ±45° vertical
- Tagging through secondary radar principle with passive tags
Sensors for environmental monitoring of mobile and/or autonomous systems are becoming increasingly important in the coming years. On the commercial level, such systems typically operate in restricted areas. Within this project, the emphasis is on mobile robots for indoor applications.
In the research world, individual robots are mainly developed for home automation and healthcare applications, which are already being evaluated on humans. However, these robots usually exhibit:
a) Very cost-intensive systems, with the sensors and computational power being the main cost drivers.
b) At the same time, these systems have low force application capabilities. This means that in case of a disturbance, people should not be harmed.
Especially in industrial robotics, cost and high force application are crucial factors because force often correlates with the accuracy of the system when handling heavy loads.
The focus within this project is precisely on industrial robotics.
Sensors needed for industrial robots and to be developed within this project are called 3D imaging sensors. They enable continuous monitoring of the entire environment.
RadRob 3D-Imaging Sensors: the Pros
There are three different competing sensor technologies on the market today, which are also used in robotic systems (stereo camera systems, LiDAR, radar systems).
