This paper proposes a Probabilistic Roadmap (PRM) planner for Autonomous Underwater Vehicles (AUVs) navigating in complex 3D environments. An improved version of PRM algorithms, called PRM*, is introduced to improve the capabilities of nodes specification, edges construction, and graph creation. For implementation, a pseudo-code for the proposed PRM* planner is provided. Numerical simulations are performed in different scenarios with increasing number of static obstacles and complexity. Evaluations of the generated collision-free paths are carried out using the Straight-Line Rate (SLR) and Computational Time (CT) metrics. Analyses and comparisons are performed to validate the significance and superiority of the proposed PRM* planner. Demonstrative results show that the PRM* algorithm outperforms the ordinary PRM one in terms of path compactness, smoothness, and collision avoidance.
We present a new method for estimating high-dimensional sparse partial correlation and inverse covariance matrices, which exploits the connection between the inverse covariance matrix and linear regression. The method...

This article describes the invention of autonomous cannabis seeding equipment to reduce contamination and planting time. The automated cannabis seeder employs an NI myRIO control board to operate a y-axis stepper motor attached to a ball screw to move along the breadth of each row of 14 seed trays. Soil drilling and burial Drill all holes at the same depth. This promotes seed germination and lowers human-seed germ contamination. These 7 soil drill heads and 7 seeders use 3D printers to design and shape the workpiece. An 800-watt air pump smokes the cannabis seeds. Linear electric motors function in two rows in the z-axis. The buffer reverses the drowning process from row 14 to the first row, starting from the 3rd row and continuing through the final series of steps until 14 rows in the y-axis are complete. The hardware controls all program activities in LabVIEW. We tested the automated cannabis seeding machine 100 times on average, sowing cannabis seeds into 98 seed trays and dropping 93 seeds at 94.80% efficiency in 10.38 minutes. A 16 percent faster machine than human work is available.
Lessons from the International Space Station (ISS) emphasize the necessity of exterior inspection for anomaly detection and maintenance, but current methods rely on costly and limited human extravehicular activities a...
