Abstract Recently, one of the most common needs people are to be connected Internet anytime, anywhere, anyhow. The Things is a materialized paradigm in which everyday objects implemented with connectivity, enabling them collect and interchange information. As energy expected more expensive, supply often not available for IoT devices, low power wide area networks attempt solution this problem. L...

In order to study passing ability of lunar rover in lunar soil, the mechanical parameters between lunar wheel and lunar soil should be analyzed. The mechanical parameters can reflect the mechanical relationship between lunar rover wheel and regolith. These parameters include sinkage, drawbar pull, driving torque, motion resistance and slip. In this paper, these parameters are measured by soil b...

This paper presents two examples of contact dynamics simulations for space robotics application: Satellite docking in GEO and rover locomotion on planetary surfaces. The contact modeling techniques include a) contact between polygonal surfaces according to the elastic foundation model theory and b) contact between digital elevation grid surfaces and point cloud surfaces with application of Bekk...

A low complexity dynamic subcarrier and power allocation methodology for downlink communication in an OFDM-based multiuser environment is developed. The problem of maximizing overall capacity with constraints on total power consumption, bit error rate and data rate proportionality among users requiring different QOS specifications is formulated. Assuming perfect knowledge of the instantaneo...

Planetary rovers are different from conventional terrestrial vehicles in many respects, making it necessary to investigate the terramechanics with a particular focus on them, which is a hot research topic at the budding stage. Predicting the wheel–soil interaction performance from the knowledge of terramechanics is of great importance to the mechanical design/evaluation/optimization, dynamics s...
