The mechanical and electrical design and controlsystem firmware/software for the Tethered Ocean Profiler (TOP), are presented. TOP is designed to autonomously sample the evolving upper polar ocean water properties from 200 m depth to within 15 cm of the ice-ocean interface while drifting with the sea ice. In addition, by repeatedly traveling up to the ice-ocean interface, TOP is able to estimate the evolving draft of the floe supporting the instrument. To date, 7 TOP systems have been fielded in the Canada Basin sector of the Arctic. Engineering data and initial scientific findings based on those data are reported and plans for system enhancements discussed.

This paper explores the shelf movement in a library system, driven by an Allen-Bradley PLC and an HMI interface. This project was part of the advanced PLC course at Michigan Technological University and involved building a prototype of library shelves using 3D printing technology. The system is controlled by a PLC, which manages NEMA stepper motors and motor drivers to facilitate shelf movement. Limit switches are employed to ensure the safe positioning of the shelves, preventing them from crashing into the walls, while a photoelectric sensor provides additional safety by ensuring the shelves do not move towards a person. This project demonstrates the integration of advancedcontrolsystems and mechanical design to automate library shelf operations efficiently.

Many applications of mobile robotics necessitate the safe execution of a collision-free motion to a defined place. Real-time obstacle avoidance strategies enable reactive motion in dynamic and unpredictable situations, whereas planning approaches are best suited for achieving a goal position in known static environments. A ROS-based approach is presented to address the challenge of robot SLAM, which has been used in real-time applications to map the environment, localize the robot within the environment, plan paths, and avoid obstacles. It is demonstrated that all navigation modules can coexist and work together to reach the destination without colliding with static and dynamic obstacles. This paper provides a platform for guiding a mobile robot in a real-world environment autonomously for different waypoints while avoiding static and dynamic obstacles using the Graphical User interface (GUI). The developed GUI-based navigation simplifies the complex ROS navigation systemcontrol to an easy user-friendly interface so that anyone can control the mobile robot platform. Our results were validated at Chosun University in South Korea, through the experimental test in an indoor environment.
