Based on a CEA-Leti algorithm, embedded receptor architecture and ultra-wide-band (UWB) technology, the system has been optimized and customized for a variety of essential factory-floor jobs supported by Desoutter, a provider of industrial electric and pneumatic assembly tools.
“The first function of this new localization system that Desoutter is bringing to market is to make sure that the right tools are used in the right zones on the factory floor,” said Emmanuel Sabonnadiere, CEO, CEA-Leti. “Following that, the system ensures that the right sequence of tasks is performed by the operator. The system automatically locks itself if an operator tries to operate a sequence outside the approved area.”
“This technology is a strong enabler for quality-process management,” said Pascal Roussy, Desoutter research & development manager. “In addition, the combination of localization and communication can help our customers meet their Industry 4.0 goals for faster, more efficient and more customer-centric operation.”
The technology is based on UWB radio modules and allows localization accuracy in the order of 10 centimetres in manufacturing environments. CEA-Leti developed and implemented the media access control (MAC) scheduling algorithms for both data and localization, as well as the localization algorithms for different deployment strategies.
The research centre leveraged its 10 years of algorithmic-location research combining a diverse range of technologies. These include motion sensors (inertial sensors, accelerometers and magnetometers), received signal strength indicator (RSSI), the global navigation satellite system (GNSS), cameras and ultra-wide-band radio customized to deliver optimal performance in Desoutter’s industrial tools.
This R&D partnership is part of a larger collaboration between Desoutter and CEA’s technology-branch institutes. The CEA and Desoutter teams will pursue their R&D efforts to further the digitalization process in manufacturing.
