    Investigators from Guangdong University of Technology Target Robotics (Leg-kilo: Robust Kinematic-inertial-lidar Odometry for Dynamic Legged Robots)

    86-86页
    查看更多>>摘要:By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-New research on Robotics is the subjec t of a report. According to news originating from Guangzhou, People's Republic o f China, by NewsRx correspondents, research stated, "This letter presents a robu st multi-sensor fusion framework, Leg-KILO (Kinematic-Inertial-Lidar Odometry). When lidar-based SLAM is applied to legged robots, high-dynamic motion (e.g., tr ot gait) introduces frequent foot impacts, leading to IMU degradation and lidar motion distortion." Financial support for this research came from Guangdong Basic and Applied Basic Research Foundation. Our news journalists obtained a quote from the research from the Guangdong Unive rsity of Technology, "Direct use of IMU measurements can cause significant drift,especially in the z-axis direction. To address these limitations, we tightly c ouple leg odometry, lidar odometry, and loop closure module based on graph optim ization. For leg odometry, we propose a kinematic-inertial odometry using an on- manifold error-state Kalman filter, which incorporates the constraints from our proposed contact height detection to reduce height fluctuations. For lidar odome try, we present an adaptive scan slicing and splicing method to alleviate the ef fects of high-dynamic motion. We further propose a robot-centric incremental map ping system that enhances map maintenance efficiency. Extensive experiments are conducted in both indoor and outdoor environments, showing that Leg-KILO has low er drift performance compared to other state-of-the-art lidar-based methods, esp ecially during high-dynamic motion."

Accordin g to news reporting from Qinhuangdao, People's Republic of China, by NewsRx jour nalists, research stated, "To improve the precision of the 2RPU/UPR+R+P hybrid r obot and fulfill production requirements, error compensation was explored. The r obot's fixed coordinate system was first used to analyze the workbench error map ping matrix." Financial support for this research came from National Natural Science Foundatio n of China (NSFC). The news correspondents obtained a quote from the research from Yanshan Universi ty, "Next, the correlation between the joint geometric errors and the moving pla tform kinematic errors of the parallel robot module was examined. The sensitivit y of joint geometric errors to the kinematic errors across the entire workspace was determined using statistical methods. Then, a genetic algorithm was employed to identify the joint geometric errors, leading to a kinematic model that accou nts for these inaccuracies. Subsequently, the accuracy of the robot was measured,and the results showed that the accuracy of the hybrid robot was improved by 7 2% in the X-axis direction with poor accuracy. Finally, a sample p rocessing experiment was conducted by the robot."

    Findings on Machine Learning Reported by Investigators at Beijing University of Chemical Technology (Combining Machine Learning and Molecular Simulation To Expl ore Mof Materials That Contribute To Cf4/n2 Separation)

According to news reporting originating from Beijing, People's Republ ic of China, by NewsRx correspondents, research stated, "Highthroughput molecul ar simulations and machine learning algorithms have been widely used to identify promising metal-organic frameworks for gas separation. However, most studies ar e limited to screening highperformance materials from existing databases, which fails to fully utilize the predictive function of machine learning." Financial support for this research came from National Key R & D P rogram of China. Our news editors obtained a quote from the research from the Beijing University of Chemical Technology, "This paper combines genetic algorithms and high-through put screening to deeply mine anion-pillared MOF (APMOF) performance feature rela tionships and predict high-performance materials that are not in the database. C onsidering the actual industrial conditions (CF4/N2 = 10/90), we chose the ratio of CF4:N2 = 1:9 to simulate the adsorption separation of gas mixtures of MOF ma terials at a temperature of 298 K and a pressure of 1 bar. First, the CF4/N2 sep aration properties of MOFs in the APMOF library were obtained based on molecular simulations. Then, the filtered data were coded according to the method of ‘bui lding block classification structural interval categorization'. Then, the machin e learning algorithm was used for model training to obtain a high-precision mode l. Finally, the tangent adaptive genetic algorithm was used to recombine the gen es of the materials, and the new MOF materials were successfully reverse-enginee red. The study found that the pore-limit diameter of APMOFs is most conducive to the separation of CF4/N2 by MOFs when the pore-limit diameter of APMOFs is with in two times the molecular dynamics diameter of CF4. 134 MOF materials were pred icted to have CF4/N2 selectivities exceeding 46.30. The use of organic ligands s uch as 4,4 ‘-bipyridyl or 1,4-bis(4-pyridyl)benzene (bpb) increases the likeliho od of these materials being high-performance for CF4/N2 separation. The combinat ion of computational screening methods and machine learning can expedite the des ign and development of new high-performance MOFs."

According to news reporting from Sion, Switzerland, by NewsRx j ournalists, research stated, "Thermo-catalytic conversion of CO2 into more valua ble compounds, such as methane, is an attractive strategy for energy storage in chemical bonds and creating a carbon-based circular economy.

The news correspondents obtained a quote from the research from the Swiss Federa l Institute of Technology Lausanne (EPFL), "Herein, we present an interpretable, human-in-the-loop active machine learning framework to efficiently plan catalyt ic experiments, execute them in an automated set-up, and estimate the effect of experimental variables on the catalytic activity. A dataset with 48 catalytic ac tivity tests was compiled from a design space of Ni-Co/Al2O3 catalysts with over 50 million potential combinations in only eight iterations. This small dataset was found sufficient to predict CO2 conversion, methane selectivity, and methane space-time yield with remarkable accuracy (R-2 > 0.9) f or untested catalysts and reaction conditions. New experiments and catalysts wer e selected with this methodology, leading to experimental conditions that improv ed the methane space-time yield by nearly 50% in comparison to the previously obtained maximum in the dataset. Interpretation of the model predict ions unveiled the effect of each catalyst descriptor and reaction condition on t he outcome. Particularly, the strong predicted inverse trend between the calcina tion temperature and the catalytic activity was validated experimentally, and ch aracterization implied an underlying structure-performance relationship. Finally,it is demonstrated that the deployed active learning model is excellently suit ed to predict and fit kinetic trends with a minimal amount of data."
