Abstract

During extraterrestrial planet exploration programs, autonomous robots are deployed using separate landers. In this paper, a concept of a novel legged robot is introduced which has inbuilt the features of lander and rover, including landing and walking capabilities as well as being deployable, orientation adjusted and terrain adaptable. Firstly, motion characteristics of the novel legged robot mapping its functions are extracted, which can be divided into global and local motion characteristics. Secondly, structures of legs are designed according to the extracted motion characteristics, mainly composed of upper and lower parts. Finally, numerous structures of legged mobile landers are obtained and presented by assembling the same or different structures of legs.
