While such a model enables accurate control of the actuator, hence the actuated mechanism; in our case a robotic arm, it also eliminates the need for a force/torque sensor for performing high fidelity force/torque control tasks.
An iterative procedure is developed to find optimal light intensities in photostrictive actuators that best match the actuated shape to the desired one.
The hysteresis of the actuated strain was continuously delayed in electrochemical actuators, whereas the strain was uniformly actuated in the electro-magnetic actuators.
A 20 W DC motor with gearbox is also used as the actuator for joint 1. Joint 3 is mounted to the actuated block of joint 2. To realize the inserting motion, ball-screw mechanism is used.
Tunable optical gratings (TOGs) based on dielectric elastomer actuator (DEA) are combined with triboelectric nanogenerator (TENG), where the actuated strain of DEA under the drive of TENG can regulate the grating period.
The actuated strain decreased with increasing frequency in both electrochemical and electro-magnetic actuators.
The JTI value of the actuated joint is 1.
The actuated joint of the RSS branch is also the revolute joint attached to the base.
We compared our method with the fixed control, the actuated control and also Wiering's method.
The actuated strain was compared with frequency, applied voltage, and wave type.
The actuated revolute joint is attached to the base, and the JTI value of the joint is 1.
