When dealing with passive walking, it has been proved in the literature that the compass-like biped robot can walk down without actuation and with a stable gait. However, the stability of gait is very sensitive to disturbances such as ground irregularity, default in manufacturing, etc. Thus, in this paper, we propose an approach to control the biped robot gait when it has disturbance. This approach...
The bending failure of anodized aluminum in tartaric/sulphuric acid bath was modeled using Doehlert design. Bath temperature, anodic current density, sulphuric acid, and tartaric acid concentrations were retained as variables. Thickness measurements and 3-point bending experiments were conducted. The deflection at failure (Df) and the maximum load (Fm) of each sample were, then, deducted from the...
In this paper, a new RLC low voltage chaos generator using second-generation current conveyor (CCII) as active building block is presented. The applied CCII was optimized with respect to static and dynamic performances thanks to an optimizing heuristic. The resultant high performances CCII has 1.406 GHz GHz and 1.53 GHz as current and voltage bandwidth respectively, and 180Omega as Rx input port resistance...
