In order to solve the problem that the performance of the existing photovoltaic (PV) modules cleaning manipulators is not high in the common working space. An improved Harris Hawks Optimization algorithm was proposed to optimize the size of the manipulators. The orthogonal crossover operator is introduced into the algorithm
which makes the local search ability stronger. According to the actual PV modules installation parameters of the power plant
the constraint index of the workspace is established
and the global performance index and the structure length index of the common workspace are taken as the objective function. The simulation results show that the optimized algorithm is faster
and the two proposed indicators are increased by 21.27% and 8.72% respectively
and the time required for the optimized robotic arm to reach the target position is shortened by 21.7% compared with the previous optimization under the same operating environment
which improves the flexibility of the manipulators and improves the efficiency of PV modules cleaning.
