SafeLog is presented at the workshop “HORIZON2020 ROBOTICS PROJECTS: SUCCESS STORIES” on the 13th of April from 15:40 to 17:00 pm.
For the first time, a project general assembly has been hold remotely… project tasks are almost completed and project goal almost achieved. The only main open issue is the demonstration in real-environment. Project partners are still optimising individual components and carefully plan the final testing set up accordingly to the available data and taking account the current situation. This was also the main discussion point of the general assembly. Another topic of the meeting was exploitation potentials and plans after project end. Here very helpful advices were given by Advisory board members, which were also participating in the meeting.
The paper “UWB Propagation Characteristics of Human-to-Robot Communication in Automated Collaborative Warehouse” has been presented on the IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting (https://2020apsursi.org/) that took place online on 6th of June 2020. In it, propagation of UWB Gaussian signal in a model of automated collaborative warehouse is analyzed using ray tracing method. The transmitting antenna is placed on the human body while the received power profiles in warehouse containing empty racks and racks filled with different loads are calculated. This gives rise to estimation of safe communication range between humans and robots.
As many other projects, SafeLog was affected by the coronavirus pandemic … especially travel restrictions hindered us to undertake real-environment tests so far. These tests have therefore been delayed to Automn 2020 – and the project got 6 months more time for that!
The paper “Analysis of Safe Ultrawideband Human-Robot Communication in Automated Collaborative Warehouse” has been presented in the poster session of the 14th European Conference on Antennas and Propagation (EuCAP 2020, https://www.eucap2020.org/) held online in period from 1st to 30th of June 2020.It presents the propagation analysis of ultrawideband Gaussian signal in an automated collaborative warehouse environment where human and robots communicate to ensure that mutual collisions do not occur. The warehouse racks are principally modeled as clusters of metallic (PEC) parallelepipeds, with dimensions chosen to approximate the realistic warehouse. The signal propagation is analyzed using a ray tracing software, with the goal to calculate the path loss profile for different representative scenarios and antenna polarizations. The influence of the rack surface roughness onto propagation is also analyzed. The guidelines for optimum antenna positions on humans and robots for safe communication are proposed according to the simulations results.
The consortium should have the opportunity to organise in the coming months real-environment testing and demonstration in a warehouse of a German company. The project was therefore extended to enable achievement of this final step. In addition, presentation of the SafeLog system is planned at the IROS 2020!
The paper “Modelling of Ultrawideband Propagation Scenarios for Safe Human-Robot Interaction in Warehouse Environment” has been presented on the 23rd International Conference on Applied Electromagnetics and Communications (ICECom 2019) (http://www.icecom.org/) in Dubrovnik, Croatia, on 1st October 2019. It presents an idealized warehouse environment where human and robots are both present and need to communicate to avoid mutual collisions. The warehouse shelves are modelled as metallic (PEC) parallelepipeds, which is the largest obstacle of practical interest, while for communication an UWB Gaussian signal at 3.994 GHz and 468 MHz width is used. The signal propagation is analyzed using ray tracing software, with the goal to determine the range of communication and the optimum antenna configurations. Several scenarios have been analyzed and discussed. It is found that the major influence on the communication range is exhibited by type of polarization of antennas placed on human and robot, while the optimum range is obtained when all the antennas are vertically polarized.
The sixth general assembly of SafeLog was hold in the wonderful Zadar in Croatia on September 26-27, 2019. During the meeting the partners presented the status concerning final developments and optimisations on the individual system components (e.g. SV, FMS, AGV). Major task still open now is to complete integration of the all components, which is planned to be achieved in the coming month at Swisslog premises in Augsburg.
SafeLog at LogiMat 2019
The SafeLog concept was exhibited at the LogiMat trade fair in Stuttgart, Germany from 19th-21st, Feb 2019. A total of 1,624 companies from 42 countries, gathered this year to present their latest developments and system solutions for efficient intralogistics to an audience of industry professionals. LogiMAT 2019 attracted a total of 61,740 industry professionals over three days. The EU-project SafeLog was exhibited at the Fraunhofer IML booth in Hall 1. The Safety concept of Safelog attracted a lot of companies that intend to put forward the safety of human workers in their Warehouses. The human-robot interaction aspect was quite interesting to the acedemic visitors. Overall the project received overwhelming interest from the visitors at the Fair.
