Kinematics model of bionic wheel-legged lunar rover and its simulation analysis
, 2009 Based on the principle of double-half-revolution mechanism, a new-style bionic wheel-legged lunar rover was designed in this paper. Its mobile mechanism is comprised of four identical wheel-legged mechanisms, rover body bracket and steering brackets, etc.

Ibis, EarlyView.While many visual predators feed exclusively during the day, others exploit foraging opportunities at night, although the efficiency with which they do so is strongly influenced by ambient light levels. We investigated the influence of variation in nocturnal light on the foraging behaviour of a small pelagic seabird, the European Storm‐petrel ...

Coordinated motion control model of a six-wheeled rocker lunar rover
Advances in Mechanical Engineering, 2016 At present, control methods of the six-wheeled rocker lunar rover primarily consist of setting the same driving parameters for each wheel. This type of control method ignores the multiple active driving characteristics of the lunar rover and causes ...

Experimental Physiology, EarlyView.Abstract Bed rest accelerates bone loss and may exacerbate skeletal fragility. This study examined the effects of 14 days of head‐down tilt bed rest (HDBR) with or without exercise, and subsequent recovery, on bone turnover, density and structure in older adults. Twenty‐two healthy older adults (55–65 years) completed the HDBR protocol.
