Choose the most-actuated limb to be decomposed into serial and parallel parts.
Compliant amplifying mechanisms and guiding mechanisms are prevalently adopted in most present piezo-actuated precision positioning stages.
When the controlled outputs are selected to be the actuated coordinates, most periodic walking gaits for this robot are unstable, that is, the eigenvalues of the linearized Poincaré map (ELPM) is larger than one.
In this work the electrical performance of micromachined piezoelectric cantilevers having different designs is investigated in liquid environment, thus making most beneficially use of their self-actuated and self-sensing capability.
Originally, most systems for stopping vehicles were mechanically actuated drum brakes with internally expanding shoes; i.e., foot pressure exerted on the brake pedal was carried directly to semicircular brake shoes by a system of flexible cables.
Then, it is proved that any axis fixed to the spacecraft can be pointed along an arbitrary inertial direction by at most two sequent rotations around the two actuated axes.
In most cases, the plows are mounted on hydraulically-actuated arms, allowing them to be raised, lowered, and angled to better move snow.
The most common control devices inside the transmission are hydraulic actuated clutches.
Great care has been given to every actuated movement, and the results are easily the most impressive I've seen on a home robot, leaving products like Anki's Vector behind in the process.
Most of current optimization methods are constrained to the continuous actuated system with limited degree of freedom (DOF), which is infeasible to the optimization of binary control multi-DOF system.
This problem can be alleviated by using a reconfigurable parallel mechanism that consists of standard six-DOF actuated legs, which can be efficiently configured into the most suitable number of degrees of freedom required for given tasks.
