In-air fast response and high speed jumping and rolling of a light-driven hydrogel actuator
Nature Communications, 2020 Stimuli-responsive hydrogel actuators have promising applications in various fields. However, the typical hydrogel actuation relies on the swelling and de-swelling process caused by osmotic-pressure changes, which is slow and normally requires the ...

Intelligent Actuators Ways to Autonomous Actuating Systems
IFAC Proceedings Volumes, 1992Abstract The integration of microelectronics within the actuator allows to not only replace the analog position controller but to add several functions which give the actuator more intelligent functions. The actuator control is performed in different levels and includes adaptive nonlinear control, optimization of speed and precision, supervision and ...

Force Sensorless Admittance Control With Neural Learning for Robots With Actuator Saturation
IEEE transactions on industrial electronics (1982. Print), 2020In this paper, we present a sensorless admittance control scheme for robotic manipulators to interact with unknown environments in the presence of actuator saturation. The external environment is defined as linear models with unknown dynamics.
