Aiming the case that vibrations and shocks of micro rescue robot parts caused by the unsmooth locomotion of micro rescue robot, in order to ensure the smoothness of the micro rescue robot trajectory and no collision, eventually to arrive the desired position and orientation, based on the basis of the kinematics and dynamics, according to the micro rescue robot joint movement characteristics, trajectory planning use the D-H method and the track is divided into acceleration, constant speed, and the deceleration three motion segments to discuss, this is of great significance to solve the smooth of micro rescue robot to work in different environments and real-time control and accuracy problems.

“…This section reviews existing literature along with a discussion of future research challenges. A genetic algorithm (GA) technique is proposed to optimize the geometry of square-shaped MPA for WB and broadband applications [27][28]. Therefore, Silva et al [29] suggested a circular-ring MSA design optimization by using the selforganizing GA (SOGA) technique with UWB features.…”

A novel optimization concept for modeling irregular-shaped patch antenna with high bandwidth and efficient radiation attributes is proposed in this paper, along with the ability to accomplish the design at a reduced computational and cost burden. A revolutionary computing perception is established with Gravitational Search Algorithm (GSA) and Quantum Based Delta Particle Swarm Optimization (QPSO), now known as GSA-QPSO. The suggested model employed the GSA-QPSO algorithm strategically interfaced with a high-frequency structure simulator (HFSS) software through a Microsoft Visual Basic script to enhance irregular-shaped antenna design while maintaining wide bandwidth with suitable radiation efficiency over the target bandwidth region. The optimally designed microstrip patch antenna is fabricated on an FR-4 substrate with a surface area of 30×30×1.6 mm 3 . The evaluated outcome shows 96 % supreme radiation efficacy at 2.4 GHz whereas overall effectiveness is above 84% over the entire frequency range, with a nearly omnidirectional radiation pattern. In terms of impedance bandwidth, the suggested antenna offers 126.6 % over the operational frequency range from 2.34 GHz to 10.44 GHz. Fabrication and measurement results are also used to validate the simulated results. It exhibits the proficiency of the offered antenna design to be used for real-world wideband (WB) communication drives.
