According to news reporting from Changsha, People's Rep ublic of China, by NewsRx journalists, research stated, "Hyperredundant manipul ators have strong flexibility that benefits from their redundant limb structure. However, a large number of redundant degrees of freedom will also lead the solu tion of inverse kinematics much more difficult, which restricts their motion per formance to some extent." The news correspondents obtained a quote from the research from Hunan University , "Inspired by the FABRIK (Forward and Backward Reaching Inverse Kinematics) met hod, an improved inverse kinematics solution method for the hyper-redundant mani pulator is proposed. Based on the space vector method, the kinematic model of th e manipulator is established to dynamically acquire its endpoint position, and t he workspace is further obtained by using the Monte Carlo method. The original s earch method is optimized, the include angle decoupling mechanism between adjace nt links is established to obtain the rotation angles of each joint, and the joi nt angle limitation is introduced to meet the actual manipulator structural rest riction. On this basis, the pose constraint mechanism is established to realize the control of the end-link pose, and the linear degree of freedom is introduced to realize the solution after the directional expansion of the manipulator's wo rkspace. A series of simulation experiments are carried out. In the experiments, the position error of the manipulator's endpoint is always less than 10-6 mm. M eanwhile, the comparative experimental results show that compared with the origi nal method, the proposed method exhibits higher position accuracy under the cond ition that the computation time is almost the same. In addition, in the end-link pose constraint experiment and path motion experiments, the pose error of the e nd-link is always less than 10-7 degrees, indicating that the end-link pose can also meet the high accuracy requirements under the premise of ensuring high posi tion accuracy."

    Reports Outline Robotics Findings from Carnegie Mellon University (Towards Auton omous Crop Monitoring: Inserting Sensors In Cluttered Environments)

According to news reporting out of Pittsburgh, Pennsylvania, by NewsRx editors, research stated, "Monitoring crop nutrients can aid farmers in optimiz ing fertilizer use. Many existing robots rely on vision-based phenotyping, howev er, which can only indirectly estimate nutrient deficiencies once crops have und ergone visible color changes." Financial support for this research came from National Science Foundation (NSF). Our news journalists obtained a quote from the research from Carnegie Mellon Uni versity, "We present a contact-based phenotyping robot platform that can directl y insert nitrate sensors into cornstalks to proactively monitor macronutrient le vels in crops. This task is challenging because inserting such sensors requires sub-centimeter precision in an environment which contains high levels of clutter , lighting variation, and occlusion. To address these challenges, we develop a r obust perception-action pipeline to grasp stalks, and create a custom robot grip per which mechanically aligns the sensor before inserting it into the stalk. Thr ough experimental validation on 48 unique stalks in a cornfield in Iowa, we demo nstrate our platform's capability of detecting a stalk with 94% su ccess, grasping a stalk with 90% success, and inserting a sensor w ith 60% success."

According to news reporting originating from Sherbrooke, Canada, by NewsRx correspondents, research stated, "Recently, demand for electri c vehicles (EVs) has increased significantly as people are becoming more conscio us of the environment and the need to reduce carbon emissions. The introduction of multi-motor systems in EVs has brought new challenges in terms of energy effi ciency and performance." Financial support for this research came from Canada Research Chairs. Our news editors obtained a quote from the research from the University of Sherb rooke, "This paper presents a Multi-Ensemble Learning (MEL)-based approach to de sign an Energy Management Strategy (EMS) for a Dual Motor Electric Vehicle (DMEV ) where MEL is a new powerful Machine Learning approach implemented using Python programming language. To make our study concrete, we studied a real DMEV that i s modeled using Energetic Macroscopic Representation and whose control is simula ted using Matlab/Simulink ™ The designed EMS aims to distribute the instant tor que between the two electric motors in an efficient manner, with the objective o f minimizing energy consumption as much as possible. Contrary to existing EMSs, an important advantage of our designed EMS is that it determines the instant tor que distribution in real-time (while the vehicle is running), without knowing in advance how physical parameters (such as the speed and traction force) will evo lve during the current trip."

According to news reporting originating in Guangdong, People's R epublic of China, by NewsRx journalists, research stated, "Flexible proximity se nsors mounted on robot arms boost obstacle detection in human-robot collaboratio n (HRC). However, most of the flexible sensor placements lack further analysis t o exploit the flexibility, leading to an inefficient and overpriced sensing syst em." Financial support for this research came from National Natural Science Foundatio n of China (NSFC). The news reporters obtained a quote from the research from the Harbin Institute of Technology, "In this letter, we propose a systematic method to optimize the p lacement of the flexible proximity sensor for HRC. To prepare for the optimizati on, the geometric model of a flexible sensor is built and an evaluation metric f or the detection ability is established. Based on a global search algorithm, we obtain the optimized sensor placement with a sufficient detection ability and a minimum number of sensors. An experiment was conducted to verify the reliability of the method. The comparison between the optimized placement results and the c onventional ones indicates that the proposed method could achieve better detecti on performance with much fewer sensors. This method also takes the flexibility i nto account by customizing the placement for different tasks."

According to news reporting out of Singapore, Sin gapore, by NewsRx editors, research stated, "This study compared the cost-effect iveness of open (ODP), laparoscopic (LDP), and robotic (RDP) distal pancreatecto my (DP). Studies reporting the costs of DP were included in a literature search until August 2023." Our news journalists obtained a quote from the research from Singapore General H ospital, "Bayesian network meta-analysis was conducted, and surface under cumula tive ranking area (SUCRA) values, mean difference (MD), odds ratio (OR), and 95% credible intervals (CrIs) were calculated for outcomes of interest. Cluster anal ysis was performed to examine the similarity and classification of DP approaches into homogeneous clusters. A decision model-based cost-utility analysis was con ducted for the cost-effectiveness analysis of DP strategies. Twenty-six studies with 29,164 patients were included in the analysis. Among the three groups, LDP had the lowest overall costs, while ODP had the highest overall costs (LDP vs. O DP: MD - 3521.36, 95% CrI - 6172.91 to - 1228.59). RDP had the hig hest procedural costs (ODP vs. RDP: MD - 4311.15, 95% CrI - 6005.4 0 to - 2599.16; LDP vs. RDP: MD - 3772.25, 95% CrI - 4989.50 to - 2535.16), but incurred the lowest hospitalization costs. Both LDP (MD - 3663.82, 95% CrI - 6906.52 to - 747.69) and RDP (MD - 6678.42, 95% CrI - 11,434.30 to - 2972.89) had significantly reduced hospitalization costs co mpared to ODP. LDP and RDP demonstrated a superior profile regarding costs-morbi dity, costs-mortality, costs-efficacy, and costs-utility compared to ODP. Compar ed to ODP, LDP and RDP cost $3110 and $817 less per pa tient, resulting in 0.03 and 0.05 additional quality-adjusted life years (QALYs) , respectively, with positive incremental net monetary benefit (NMB). RDP costs $2293 more than LDP with a negative incremental NMB but generates 0 .02 additional QALYs with improved postoperative morbidity and spleen preservati on. Probabilistic sensitivity analysis suggests that LDP and RDP are more cost-e ffective options compared to ODP at various willingness-to-pay thresholds."

According to news reporting from Boston, Massachusetts, by Ne wsRx journalists, research stated, "We demonstrate proprioceptive feedback contr ol of a one degree of freedom soft, pneumatically actuated origami robot and an assembly of two robots into a two degree of freedom system." The news reporters obtained a quote from the research from Northeastern Universi ty: "The base unit of the robot is a 41 mm long, 3-D printed Kresling-inspired s tructure with six sets of sidewall folds and one degree of freedom. Pneumatic ac tuation, provided by negative fluidic pressure, causes the robot to contract. Ca pacitive sensors patterned onto the robot provide position estimation and serve as input to a feedback controller. Using a finite element approach, the electrod e shapes are optimized for sensitivity at larger (more obtuse) fold angles to im prove control across the actuation range. We demonstrate stable position control through discrete-time proportional-integral-derivative (PID) control on a singl e unit Kresling robot via a series of static set points to 17 mm, dynamic set po int stepping, and sinusoidal signal following, with error under 3 mm up to 10 mm contraction. We also demonstrate a two-unit Kresling robot with two degree of f reedom extension and rotation control, which has error of 1.7 mm and 6.1°."

    Reports Summarize Robotics Study Results from Xiamen University of Technology (D esign of and research on the robot arm recovery grasping system based on machine vision)

    55-56页
    查看更多>>摘要:By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News-A new study on robotics is now available. Accordi ng to news reporting from Xiamen, People's Republic of China, by NewsRx journali sts, research stated, "With the development of urban modernization, the amount o f generated waste has been constantly increasing, making waste classification ne cessary. In the process of waste bin recycling, the main challenge is improving recycling efficiency and reducing the workload of workers. To address the proble ms of waste bin positioning and retrieval in the waste bin recycling process, th is study proposes an automatic retrieval system based on a combination of machin e vision and robotic arm motion control." Our news correspondents obtained a quote from the research from Xiamen Universit y of Technology: "The main aim is to achieve accurate and efficient detection, r ecognition, and retrieval of different types of waste bins. First, the YOLOv5 de ep learning recognition algorithm is improved using a channel pruning technique to reduce the complexity of the model while ensuring high recognition accuracy, thus facilitating the portability and deployment of the model on various mobile devices. Then, image preprocessing is conducted using the median filtering metho d and the Gamma brightness correction algorithm. The HSV color model is employed , and the H component distribution is used for classifying different types of wa ste bins under different lighting conditions. This allows for image segmentation for different-color waste bins, facilitating the classification and recognition of waste bin images. Finally, the waste bin localization algorithm and robotic arm motion algorithm are employed to accomplish the positioning and retrieval of waste bins. The experimental results indicate that compared to the original YOL Ov5 model, the improved YOLOv5 algorithm can achieve a significant reduction in parameter number, decreasing it from 7,022,326 to 2,828,675, which represents an approximately 60 % decrease. Moreover, with a marginal 0.2 % decrease in accuracy, the FLOPs value decreases from 12.9G to 7.97G, demonstrati ng a reduction of nearly 70 %. The model size is also reduced by al most 60 %. The results indicate that the recognition rates of diffe rent-color waste bins exhibit a trend of initially increasing and then decreasin g with the intensification of light. Among the four colors of waste bins, the re cognition rate of red waste bins is the highest, with an average recognition rat e of 95 %. In contrast, orange waste bins have the lowest average r ecognition rate, with an average value of 91 %. In the grasping exp eriments, the detection and grasping success rates for the red waste bins are th e highest, reaching 95 % and 80 %, respectively."
