# EfficiencyX: Study of Energy Efficiency between Two Robotic Arms
## 4 Conclusions  
According to the results of the simulation, it is recommended to manufacture carbon fiber parts, retaining the original thicknesses of the aluminum parts (4 mm). This is because if the thickness of the parts is reduced, the rigidity is also reduced, which could cause misalignment of the parts due to their bending. In addition to this, if the original thicknesses are respected, the assembly of the parts will have fewer complications. Using the carbon fiber/epoxy resin composite initially reduces the weight of the parts by 44.42%. Taking into account the results obtained, a mass reduction of approximately 54.6% is expected after optimization, while preserving the rigidity and resistance of the parts. The carbon fiber robotic arm turns out to be more efficient in energy consumption, achieving a maximum of 3.66% for tests carried out at a speed of 3000 degrees/min; the percentage value depends on the speed and torque required to move the joints.  
Future research may encompass comparative analyses of different advanced materials such as graphene and titanium alloys, optimization of the design and configuration of the robotic arm to maximize the benefits of using carbon fiber, and detailed studies on the response of this material to dynamic loads and vibrations. In addition, the findings could be extrapolated to other sectors such as the automotive industry, aeronautics, and the

development of medical prostheses, where weight reduction and energy consumption are crucial. Integration with IoT technologies and big data analytics also offers opportunities to optimize device performance in real time. Previous research, such as \"High Efficiency Manufacturing With a Smart Carbon Fiber End Effector\" [41] and \"Optimization of energy consumption in industrial robots, a review\" [42], have laid the groundwork for understanding the benefits of these materials, and the present research seeks to delve deeper into the dynamic behavior of carbon fiber joints, with the potential to transform multiple industries.
