“…MSRS can be adjusted to the optimal launch configuration according to the diameter of the rocket fairing and return to the normal operating form after orbit by configuration transformation. Depending on the mission requirements, the spacecraft modules of the original configuration can be adapted to the best configuration for the mission [4,5]. MSRS has the following advantages: (1) autonomous and fast configuration transformation; MSRS configuration transformation does not require the assistance of the service spacecraft, saving the transformation time and providing better mission adaptation;…”

The modular self-reconfigurable satellites (MSRSs) are a new type of satellite that can transform configuration in orbit autonomously. The inverse kinematics of MSRS is difficult to solve by conventional methods due to the hyper-redundant degrees of freedom. In this paper, the kinematic model of the MSRS is established, and the inverse kinematic of the MSRS is transformed into an optimal solution problem with minimum pose error and minimum energy consumption. In order to find the inverse kinematic exact solution, the refractive opposition-based learning and Cauchy mutation perturbation improved differential evolutionary algorithm (RCDE) is proposed. The performance of the algorithm was examined using benchmark functions, and it was demonstrated that the accuracy and convergence speed of the algorithm were significantly improved. Three typical cases are designed, and the results demonstrate that the optimization method is effective in solving the MSRS inverse kinematics problem.

“…Very few studies investigate the self-assembly of millimeter-size particles, where gravity, inertia and hydrodynamic interactions prevail. Yet, self-assembly can become a manufacturing technique for millimeter-scale objects that are inconvenient for robotic manipulation, 18,29,35,36 especially when formation times are not a limiting factor. 1 Furthermore, millimeter-scale self-assembly can provide valuable insight relevant to micron and nano-scale processes.…”
