In view of the detection requirement in dim and low gravity environments of the south pole of the Moon and the canyons of Mars, it is urgent to explore intelligent and efficient robot control and management methods so that robots can reliably complete complex tasks of planetary exploration, support the construction of lunar and Mars bases, and ensure long-term development. On the basis of elaborating the definition of dim and low gravity environments and analyzing the latest progress of robots, the challenges brought by dim and low gravity environments to planetary exploration robots are discussed, and the development trend of intelligent robot operation in dim and low gravity environments is summarized. Some suggestions on the development of intelligent robot technology are put forward from the perspective of intelligent robot behavior control and intelligent operation management.

A micro-opto-electro-mechanical system (MOEMS) accelerometer features high precision, electromagnetic interference resistance, good adaptability to the environment, high reliability, and easy miniaturization, which is the major development trend of inertial instruments. According to the optical measurement principle, this paper divides MOEMS accelerometers into three categories, which are based on the direct intensity modulation (IM), the undulatory property of light, and the light-matter interaction separately. Following a brief introduction to the measurement principles and typical cases, we systematically analyze the merits and demerits of the three accelerometers, as well as their potential application scenarios. Given the research progress in MOEMS accelerometers, we also present their development tendencies.
