    Conventional constant-power design methods for magnetic components tend to result in oversized and inefficient solutions for pulsed power load applications. This manuscript introduces an innovative framework that categorizes magnetic components according to the correlation between the application's pulse period and the component's thermal time constant τ. Three distinct design categories are established using a thermal/electrical equivalent model: average power, oscillating temperature, and peak power magnetics. The classifications are integrated into a multivariable optimization process to produce Pareto fronts representing total volume against power loss for diverse PPL applications, such as medical imaging and regenerative braking. The analysis suggests that designing for oscillating or peak temperatures can significantly enhance power density, leading to a reduction in component volume by as much as two orders of magnitude compared to traditional designs. This framework offers a systematic method for application-specific PPL magnetic design, marking an essential advancement toward establishing a standardized methodology similar to the IEC 60034-1 duty-cycle classifications for electric motors.

    This project presents the design, modelling and implementation of a system, which allows controlling a robotic arm through movement commands captured by an exoskeleton adapted to an upper limb. A study of degrees of freedom, joint movement angles and limitations that will have both the robotic arm and the exoskeleton was performed. The mechatronics design methodology based on the V-Model was used. The mechanical, electrical and control designs were developed concurrently in a way that one does not compromise the other's integrity. The mechanical design is realized and simulated in a CAD software to verify the operation and movement freedom that the user will have. Batteries are dimensioned to power the exoskeleton and the robotic arm. After integration of the systems designed, requirements assurance is performed. The robotic arm is able to replicate the movements made with the exoskeleton; the reaction time in slow movements is in real time, while for high reflections this present a delay up to 0.42 seconds. The robotic arm is able to lift 250 g without compromising its reaction speed. The ratio of movements between robotic arm and exoskeleton has a tolerance of up to 5 degrees.

    Mobile robotic platform that allows the search of people after an earthquake has occurred along with a low-scale fire mitigation system was presented. The mechanical, electrical-electronic system and a wireless control interface for the operation and transmission of video of the mobile robot have been developed. The design of the mechanical system allowed the implementation of a mobile platform that enters complex terrains and a robotic arm with 4 degrees of freedom whose functions are the delivery of first aid kits and the manipulation of the fire mitigation system. The electrical-electronic system is in charge of controlling the electromechanical actuators of the system. The supervision and monitoring system uses two cameras on the robot that transmit the video to external monitors or mobile devices. This allows safeguard the integrity of rescuers by supporting them in their search and assistance tasks providing a technological alternative to the teams dedicated to solve this problems. Field tests were carried out at the training and training center of the public company EMBA-EP, which allowed validating the operation of the platform.
