In this paper, Chameleon Swarm Algorithm, which is a new metaheuristic algorithm, is used to design a speed reducer gearbox. The gearbox is used in an autonomous vehicle, and it is supposed to take in consideration the total weight of the gear sets along with other contains that include the stresses; including the bending and surface stresses for the gears and the stresses of the shaft, and he deflections of the shafts, beside other contains. The algorithm must find the optimal solution while satisfying the eleven constraints, which makes it a multi-objective optimization problem. The algorithm minimizes the energy dissipation in the gears as the design is optimal. The algorithm will be tested in Monte Carlo simulation to show its stability and robustness in such an application. The computer resources are examined, and the results are compared to the particle swarm optimization. The proposed method shows better results and better performance compared to the PSO.

Bionic limbs have transformed the lives of individuals with missing or damaged limbs, enabling them to regain independence using electronic sensors and motors. Over the years, significant advancements have been made in prosthetic devices, with some reaching a level of sophistication that is almost indistinguishable from natural limbs. However, not all amputees have equal access to cutting-edge technology, which motivates the research and development presented in this paper. In this study, we have designed and developed a bionic arm that can be easily manufactured using additive manufacturing, paired with a wearable sensor suit that commands the actuators to execute movements. The use of gesturecontrolled wearable sensors allows for the creation of sophisticated bionic arms with applications in both civilian and military contexts. Furthermore, the team is exploring the use of advanced computer algorithms to enable fast and fluid movements, facilitating the performance of complex tasks with prosthetic limbs. This paper provides a general design overview of the bionic arm and its sensor suit, showcasing the potential of this innovative approach in revolutionizing the field of prosthetics. The use of additive manufacturing and wearable sensor technology opens up new possibilities for providing accessible and advanced prosthetic solutions for individuals with limb loss.
