Abstract
To enhance travelling performance on soft terrains, a novel wheeled mechanism named Active Lugged Wheel (ALW) for accessing sandy terrains has been proposed in our previous study. Based on this concept, a dust-proof ALW prototype towards field experiments is developed in this paper. The superior performance is verified by experimentally comparing the new wheel to conventional fixed lugged wheel. It has been found that the ALW generates larger drawbar pull and vertical force over a wider range.
