Abstract:
The training of lunar rover driving skills for astronauts requires the simulation of realistic motion perception characteristics.The key lies in understanding the differences of driving motion perception between ground and moon.A high-fidelity simulation scene was created to compare the driving characteristics of a lunar rover on the moon and on Earth.Additionally,a software framework based on spatial orientation model was developed to simulate and compare the differences in forward motion perception between lunar and ground driving.The results indicate that under lunar conditions the lunar rover experiences reduced acceleration changes and slower acceleration and deceleration,which increases the displacement of sideslip.Additionally,limited visual information leads to a significantly larger dynamic pitch angle perception compared to ground conditions,while static pitch angle perception is greatly reduced.However,this difference could be greatly reduced when visual information is available.The differences in motion perception characteristics were revealed between lunar and ground driving rover,providing a basis for optimizing lunar rover driving motion simulation strategies.
