Owing to an increase in diverse disaster incidents instigated by natural catastrophes and human error, extensive research on mobile robots, designed for disaster environment comprehension and human rescue operations, and has become more prevalent. Specifically, endeavors are being undertaken to equip mobile robots with grippers, enabling confined space navigation and life-saving activities within disastrous circumstances. Prominent among these are investigations into hybrid grippers and actuation systems, utilizing both hard and soft materials for obstacle removal. Nevertheless, for effective deployment of mobile robots within real disaster scenarios, the necessity for a compact hybrid gripper and drive system is indispensable. This paper elucidates the design and realization of a small-scale pneumatic pump module, developed to operate the jamming module of the previously compactly implemented hybrid gripper, also incorporating discussions on performance validation experiments. The verification experiments confirmed the capability of the proposed small-scale pneumatic pump to adequately operate the jamming module, thus reinforcing the hybrid gripper's grasping performance.

This study presents an autonomous mobile robot with advanced grasping capabilities designed to perform two missions: Pick and Place and Hold and Run. The robot’s four-wheeled chassis ensures stability and maneuverability, while an articulated arm with a specialized gripper manipulates 8-cm-diameter balls. Utilizing YOLO algorithms for accurate object detection, the vision system offloads image processing to a laptop via Wi-Fi for real-time monitoring and decision. Extensive tests validated the robot’s consistent task execution, demonstrating dexterity and intelligent navigation. Challenges such as hardware integration and vision system optimization were innovatively addressed. The modular design allows for easy upgrades and adaptability, highlighting significant future potential. The proposed robot fulfilled the preset goals of picking any defined colored ball and placing them into a box autonomously. Besides, achieving the athletic runner task around the classroom interior. This project showcases the interdisciplinary nature of robotics, combining mechanical engineering, computer vision, and software development with potential applications in service robotics.

For precise control, it can be achieved through a feedforward controller with a feedback control scheme. The feedforward controller can be automatically tuned with the datadriven methods through experimental results. However, these data-driven methods are interrupted when the input disturbance is applied. This problem can be solved using Disturbance Observer (DOB) in the control loop. In addition, a data-driven method derives accurate control performance by simultaneously tuning the feedforward controller and DOB model. Furthermore, a tuning algorithm with a rational model is proposed for the corresponding modeling to a flexible system. The simulation results verify that the proposed method accurately tunes the controller for an unknown plant under an input disturbance.
