Electro-ribbon actuators and electro-origami robots

DSP Control of Electro-Hydraulic Servo Actuators

Hydraulic actuators are characterized by their ability to impart large forces at high speeds and are used in many industrial motion systems. In applications where good dynamic performance is important it is common to contain the actuator in a servo loop comprising a feedback transducer and electronic controller. The majority of electronic servo-controllers used in these systems are analogue bas...

Universal scaling and intrinsic classification of electro-mechanical actuators

A methodology for identification and control of electro-mechanical actuators

Mechatronic systems are fully-integrated engineering systems that are composed of mechanical, electronic, and computer control sub-systems. These integrated systems use electro-mechanical actuators to cause the required motion. Therefore, the design of appropriate controllers for these actuators are an essential step in mechatronic system design. In this paper, a three-stage methodology for rea...

Design of Backdrivable Mechanisms with Electro-Hydrostatic Actuators*

The importance of force sensitivity in robots that interact with unknown disturbance is acknowledged. For the manipulators, impedance controlled robots realized safe and robust object manipulation. For the legged mechanism, it is expected to enhance locomotion stability, since locomotion fundamentally is a manipulation of the center of mass. In order to maximize force sensitivity, both the forc...

Electro-Rheological Fluidic Actuators for Haptic Vehicular Instrument Controls

Force-feedback mechanisms have been designed to simplify and enhance the human-vehicle interface. The increase in secondary controls within vehicle cockpits has created a desire for a simpler, more efficient humanvehicle interface. By consolidating various controls into a single, haptic feedback control device, information can be transmitted to the operator, without requiring the driver’s visua...
