This paper presents the design and implementation of MagPlunge, a novel solenoid actuator featuring a magnetic plunger, specifically tailored for miniature segment robots. Leveraging the unique properties of magnetic forces, the MagPlunge actuator offers enhanced performance, compactness, and energy efficiency compared to traditional solenoid designs. The design considerations, fabrication process, and experimental characterization of the MagPlunge actuator are discussed in detail. Additionally, its integration into miniature segment robots is demonstrated, showcasing its potential for enabling agile and versatile robotic locomotion in confined spaces and challenging environments.
