Based on a CEA-Leti algorithm, embedded receptor architecture and ultra-wide-band (UWB) technology, the system has been optimised for a variety of essential factory-floor jobs supported by Desoutter, a manufacturer of industrial electric and pneumatic assembly tools and other equipment.
“The first function of this new localisation 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,” explained 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 localisation 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 localisation 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 localisation, as well as the algorithms for different deployment strategies.
CEA-Leti was able to leverage its many years of algorithmic-location research together with 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 customised 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 to improve quality control and provide for a safer work environment.
