This paper describes Cartesian position and force control with adaptive impedance/compliance capabilities for a humanoid robot arm including velocity control incorporate with End-Effector Fixation Control (EEFC). We successfully demonstrated the end-effector positioning to reach the target point in Cartesian coordinate frame based on force control without solving the inverse kinematic problem. The...
Single RF MIMO communication emerges a novel low cost communication method which does not consume as much power as the conventional MIMO. The implementation of such single RF MIMO system is done by mapping the weighting factors to the polarizations or the radiation patterns of the antennas. In order to have such performance, an antenna with rich pattern modes is required by the system, thus the ESPAR...
Micromachined waveguides embedded in LTCC (Low Temperature Co-fired Ceramic) multi-layer packaging substrate are excellent candidates for vacuum microelectronic devices in submillimeter wave or terahertz band, and data exchange backbone structures with high data throughput capabilities in highly integrated system-in-package (SIP). In this paper, theoretical and numerical simulation on the fundamental...
