“Sichere Mensch-Roboter Kollaboration mithilfe hochauflösender Radare”
RoKoRa: Secure Human-Robot Collaboration using High-Resolution Radars (July 2017 to June 2020)
This project is funded by the Federal Ministry of Education and Research BMBF.
In the future, humans and robots will increasingly interact directly and in confined spaces in both service and industrial robotics. To achieve this, it is absolutely essential that these systems always guarantee personal safety and at the same time ensure that the robot moves as smoothly as possible. Existing systems, however, often still have shortcomings.
Goals and Approach
The aim of the RoKoRa project is to develop a new safety system for personal safety in human-robot collaboration. For this purpose, robots are equipped with new radar sensors that form a kind of radar skin around the robot. Within this protective field, the robot can estimate movements, for example those of a person, very precisely. The robot should not interrupt its own movements, but adapt them to human movements without touching them, thus guaranteeing safe, robust and efficient interaction. The new system is to be developed taking personal safety and occupational safety into account and evaluated in a test application.
Innovations and Perspectives
The project enables new technologies for a close and direct physical interaction between humans and robots. These technologies can be transferred to many applications in the personal and domestic environment, in medicine and in industry.

sR-3402e is the one of the results of this research. The radar module was developed for 77/79 GHz FMCW radar with Texas Instruments radar chip AWR1243 and NXP radar signal processor FS32R174. The frontends were designed by partner Fraunhofer IAF and consist of 3 transmitters (3 Tx) and four receivers (4 Rx). Frequency bands from 76 to 77 GHz and 77 to 81 GHz can be applied. IMST designed and manufactured the baseband board with radar signal processing, Ethernet interface and DC supply (with Power-over-Ethernet or external 12V DC).
