During recent years there is a strong trend towards radio frequency (RF) remote controls as it is delivering even more comfort to the users and increased usability with high robustness of the RF links. Lower power consumption with new features and security make RF remote control systems more competitive with widely used IR remote control systems. In this paper we propose, a RF module based real...

The speed and maneuverability at which legged animals can travel through rough and cluttered landscapes has provided inspiration for the pursuit of legged robots with similar capabilities. Researchers have developed reduced-order models of legged locomotion and have begun investigating complementary control strategies based on observed biological control schemes. This study examines a novel con...

Certain frequency-shaped standard linear quadratic (LQ) controllers involving state feedback have attractive loop robustness properties. These robustness properties may vanish in passing to an output feedback scheme, as when state estimates are used instead of states. The known exception to date is when the plants are minimum phase and state estimation with loop recovery is used, as in LQG/LTR ...
